Experienced engineers in transformer substation can judge the equipment condition via just listening to the working sounds of electrical equipments. Use audio signal processing applied in engines and other mechanical equipments for reference. A scheme to monitor the working condition of electrical equipments is proposed. Firstly, the basic principles and system structure of this scheme is outlined. It introduces the method of colleting electrical equipments working sounds by Microphone array, because Microphone array form a beam to target the source sound, which can reduce the noise and reverberation. When substation is working, the environmental background interference sounds exist and are independent from electrical working sound. So we can use FastICA algorithm that is based on the largest negentropy to separate the collected sound to several independent source signals. It has the advantage of fast convergence and robust. The simulation result shows this algorithm can effectively separate the multiple independent source signals. The separation accuracy is above 95% for typical sample mixed sounds and the reliability of electrical equipment fault detection system based on audio signal processing is ensured.

Sound or audio engineering is a branch of the field of engineering, which involves the process of recording sound and reproducing it by various means, as well as storing in order to be reproduced later. Known as sound or audio engineers, these trained professionals work in a variety of sound production fields and expert in recording methods. They can be instrumental to implement the affordable technologies and technical process to distribute the audio data hence, making it accessible for future generations. The current role of these engineers not only to perform or limited to recording session but they create metadata for archiving and preservation for future needs. Currently, product sleeves of ethnographic recordings represent no technical elements of how traditional music recordings are produced. The product details focus only to some extent on historical elements and musical notation. To an audio archivist, declaring what devices are in a recording is not linked with preservation data. Apart from the format, the sleeved design, technical specification is essential to other social scientists such as audio engineer and field recordist of the future. The aim of the present research is to capture optimum dynamic range of the sound and applying a signal processing that would not alter the tonality, timbre and harmonic of the sound. Further applying a suitable information storage for the metadata to be preserve or archived for future accessing and reproduction.

This article explains the concept of systems and negotiations theory. The article also discusses that by applying complex systems and negotiation research to collaborative design, research scientists have come up with several sound ideas to help engineers work together toward the best product possible. According to experts, the marketplace is making increasing demands for innovative, sustainable design. Many engineered products will have to be different from anything conceptualized today. In order to get there, engineers are going to have to work together in the smoothest possible manner. Using knowledge about systems and negotiation theory, researchers have turned their attention to the way that engineers negotiate as they work together on a single design. Researchers found that to get the best digital model possible, everyone involved must give a little. The article explains that collaboration was the norm when Boeing and Marshall Space Flight Center engineers worked on the lab module for the International Space Station.

Full textAbstract:
Over the course of the past several years the use of digital audio-sampling by composers, musicians, engineers and producers has increased to a point where the sampler is now as common in the recording studio as the microphone. Digital samplers allow one to encode a fragment of sound, from one to several seconds in duration, in a digitised binary form which can then be stored in computer memory. This stored sound may be played back through a keyboard, with its pitch and tonal qualities accurately reproduced or, as is often the case, manipulated through electronic editing. Because of its unsurpassed mimetic capabilities, one common use of the sampler has been to store in computer memory a note or set of notes played by an individual who has a unique playing style. When played back through a keyboard, one could construct an entire solo line which would potentially sound as if that person were playing it. Another common use of the sampler is to extract a fragment of sound from one context and place it in a new one, with no appreciable loss of sound quality over each generation of extraction and repositioning. These three capabilities of the sampler – the mimetic/reproductive, the manipulative and the extractive – are crucial to understanding both the sampler's popularity and its potential to disrupt the production process in the music industry.

The current sound data collecting system can`t meet the demand of the engineers on special occasions to master the process of the signal acquisition from remote timely. In order to solve this problem, this article designed a real-time monitoring system which can collect the signal by a sound card and implement the analysis of the sound signal`s power spectrum and phase spectrum, storage and playback. In addition, it can use the TCP/IP protocol to transmit the signal to remote engineers timely. Practice shows us that the system has the characters of simple structure, steady data transition, low cost and friendly interaction.

Abstract Sound is fundamental to ocean ecosystems, yet the interplay of physical and biological sources and their relationships with ecological health and human activities is inherently complex and non-intuitive for visually oriented humans. Ocean Sound Atlas (OSA) will be a digital global ocean sound map. This interactive system will compile and integrate passive acoustic data by location of recording, for use by researchers, educators, policy makers, engineers, explorers, sound artists, and other stakeholder groups. The Ocean Decade is a unique opportunity to serve as the “hook” required to create and promote a central tool that will be widely used. OSA will harness increasingly exciting research potential into the ability to investigate key cross-cutting, multi-scale impactful questions.

Full textAbstract:
Music Synthesis Techniques is an advanced undergraduate course that explores how various methods are used to create and manipulate synthesized sounds used in sound design and audio production. Students explore their understanding through the creation of a series of short, one-minute compositions that utilize each technique. This paper focuses on that of granular synthesis. Granular synthesis is a music synthesis technique that is used to create unique and alluring sounds that has captivated modern music listeners. For audio engineers and sound designers, the term granular synthesis has always held an aura of mystery surrounding it. Recent developments in plug-ins for digital audio workstations allow them to easily create its signature sound, which have created a way to use granular synthesis as an art form. Unlike other methods, granular synthesis is rooted in the laws of quantum mechanics. The Heisenberg Uncertainty Principle is explored to understand how granular synthesis creates its signature sound, which in turn is then used to create artistic compositions through the manipulation of the variables. Several examples from student work as well as collaborative work will be included.

Full textAbstract:
Background: This research examines the 2017 film Pengabdi Setan scoring function. Joko Anwar wrote and directed the film Pengabdi Setan, released on September 28, 2017. This film is a remake of a 1980 film of the same name. In this film, the score is essential for visually confirming symbols or incomplete messages. There are two types of sound: diegetic sound and non-diegetic sound. Purpose: This research aims to determine how diegetic and non-diegetic sound were used to create a horror atmosphere in the film Pengabdi Setan. Methods: The authors described the audio analysis results in the form of diegetic and non-diegetic sounds using a qualitative descriptive analysis. Documented assessment and observation were employed as data collection techniques. Results: The results indicate that infrasonic sound (infrasound) and sub-bass frequencies in the form of non-diegetic sounds emotionally impact audiences. The typical frequency is 31 Hz, and although it is inaudible to the human ear, the audience can sense the vibrations of this frequency. This frequency can typically only be perceived as a “chest rumble.” In general, both diegetic and non-diegetic sounds in the film Pengabdi Setan contribute to completing the defective message symbol. The combination of infrasonic sound effects, sub-bass, and musical composition validates the visual messages or symbols. Implications: This research can theoretically serve as a resource for future researchers interested in studying diegetic and non-diegetic sound in film. Directors and cinema sound engineers can use this research to construct diegetic and non-diegetic sound in their films, particularly horror films.

Full textAbstract:
AbstractWhen a stereophonic track is heard through headphones or over loudspeakers, the image of a virtual performance is created in the mind. This virtual performance, which exists exclusively on the record, can be conceptualised in terms of the ‘sound-box’ (Moore 1993), a four-dimensional virtual space within which sounds can be located through: lateral placement within the stereo field; foreground and background placement due to volume and distortion; height according to sound vibration frequency; and time. From the mid-1960s, the increasing shift from mono to stereo meant that producers and engineers had to contend with the notion and potential of a song's sonic arrangement or mix, resulting in a disparity of sonic placement and a diverse range of sound-box configurations. By 1972, a normative positioning of sound sources within the sound-box was established, which we term the ‘diagonal mix’. This article focuses on the consolidation of this norm by means of a ‘taxonomy of mixes’ and the utilisation of visual representations which detail the sound-box configurations of a variety of pop/rock, easy listening and psychedelic tracks from 1966 to 1972.

What an acoustic engineer does is generally not well understood by high school students, and this likely applies to the broader architecture and design fields. Acoustic engineers and architects who are engaged in the design of high schools and classrooms also may not have been in a class of students since they left school. This presentation outlines a Problem Based Learning experience run for high school students in Australia which provided insight into the above gaps for both students and practitioners. The student-centred challenge has been run in two formats. The first was run weekly over three 100 minute sessions, while a condensed format was later run as an 80 minute hands-on design challenge. Both formats involved an architect(s) and an acoustician facilitating the challenge. The students considered the use, acoustic requirements and affordances of design in a classroom. Students were given a classroom with poor acoustics and challenged to develop and present a design solution which improved the area for learning, including room acoustics. The challenge involved mathematics (Sabine equation), measurement (including scale and reverberation time), and architecture.

Urban Air Mobility (UAM) is quickly developing with the objective to transport passengers and cargos at lower altitudes in urban areas using automated aircrafts. Noise is one of the important challenges facing engineers developing these aircrafts as they will be operating in cities and are thus subjected to noise regulations. In addition, customers will be expecting similar interior noise performance as in luxury automotive vehicles. This paper presents an engineering process developed to predict the acoustic performance inside Electric Vertical Take-off and Landing (eVTOL) aircrafts. The process starts with Computational Fluid Dynamics (CFD) simulations to calculate the noise sources generated by the propellers. A Boundary Element Model (BEM) is then used to propagate these sources around the aircraft and calculate the pressure distribution on the fuselage exterior, which is then applied, in the last step, as excitation in a Statistical Energy Analysis (SEA) model to predict the interior noise. The paper uses a demonstrator model to illustrate the process and results. This process is now available to support engineers when optimizing their eVTOL design for costs, weight and interior noise performance without the need for physical prototypes.

Full textAbstract:
The essay “Divinations” focuses on Robert Rauschenberg’s Oracle (1962-1965), a work whose making and display entailed close collaboration between the artist and the engineers Billy Klüver and Harold Hodges, both of Bell Laboratories. The piece stemmed from Rauschenberg’s interest in sound, sculptural form, and radio networks: it housed ten radios and speakers in various sculptural elements constructed from found metal objects, including ducts, window frames, a bathtub, and a car door. Audience members could turn dials that indirectly modified the volume and tuning of the radios. Walking through the sculptural installation, one experienced shifting acoustic, spatial, and visual effects. This text seeks to understand how the interactions between artist and engineers—and between sound sculpture and viewers—engaged systems of industrial and postindustrial production, broadcast radio, and audiovisual reception.

On January 11, 2016 the U.S. Army Corps of Engineers (USACE) New England District (NAE) completed a Final Dredged Material Management Plan (DMMP) for Long Island Sound (LIS). The DMMP was requested by the Governors of Connecticut and New York, in their letter of February 8, 2005 to the Chief of Engineers, following the U.S. Environmental Protection Agency’s (EPA) publication in April 2004 of the Long Island Sound Dredged Material Disposal Site Designation Study Final Environmental Impact Statement. The LIS is a large coastal estuary located between Long Island, New York on the south, and the shores of New York, Connecticut and southwestern Rhode Island on the north. A total of nearly 240 harbors, coves, bays and rivers supporting various levels of navigational access are located along these shores. Twelve Congressional districts and 112 municipalities border the Sound and its adjacent waters in the three states. The ideals, goals, and needs along the LIS do not always align and thus the need for open communication throughout each dredging project.

There is growing public perception that nanotechnology products are flourishing without sufficient care for the risks they pose to life, global, and local environments. The transparency of safety issues and impact on environment should be the prime focus while engaging a particular field with nanotechnology. Testing of nano products needs to be enforced before they are released to the market. Whether nanotechnology is good or bad for the environment is totally based on the nature of its use and considerations made during its application. The use of nanotechnology in any field requires great care, and any sort of negligence is likely to bring negative effects for the environment and its habitats. Recent studies show that the lack of knowledge as regard risks is found even at the expert level. The present work highlights the risks associated with the use of nanoparticles and the necessary preventive measures for using the technology in a safe and sound way.

Two venues will be shown with controlled sound system tests measured compared with propagation computer models. In addition, iterative design efforts with architectural noise control to reduce impact on the nearby community will be shown, in particular an attempt to reduce low frequencies and the limits of modeling standards in regard to diffraction.

The need to reduce the sound and vibration characteristics in the aerospace industry is continuously increasing because of the need to meet FAA regulations, to reduce noise pollution, and to improve customer satisfaction. To improve customer satisfaction, aircraft and engine manufacturers must work to control sound and vibration levels so that passengers do not experience discomfort during a flight. Sound and vibration characteristics of a fixed-wing aircraft with jet engines are composed of complex-frequency contents that challenge engineers in the development of quiet engine designs, aerodynamic bodies, and advanced sound- and vibration-attenuating materials. One of the noisiest parts of an aircraft, the gas turbine, was analyzed in this research. In Part 1 of this project, the use of alternative fuels in a gas turbine engine was investigated to determine whether those fuels have negative effects on sound and vibration levels. Three types of fuels were used: Jet A as the reference fuel, natural gas–derived S-8, and coal-derived isoparaffinic kerosene (IPK). The alternative fuels, S-8 and IPK, are Fischer–Tropsch process fuels. Overall sound and vibration characteristics of the alternative fuels presented a similar pattern across the frequency spectrum to those of the reference fuel, with the alternative fuels being slightly quieter. In Part 2, the sound path was treated by introducing sound-absorbing materials and investigating their acoustic performance. A melamine-based foam and soy-based foam were used in this research. Melamine is very lightweight, has excellent thermal endurance, and is hydrophobic. The soy-based foam was selected for its potential application in the aerospace industry to work toward a greener aircraft, in an effort to promote environmental sustainability. The soy-based material reduced the sound level by more than 20 dB(A) and presented better performance than the melamine at high frequencies.

ABSTRACTFor improving the performance of a miniature loudspeaker, engineers have been pursuing a goal of lowering its first damped frequency to have a broad and smooth region of its sound-pressure-level response. This article applies the approach of electro-mechano-acoustical analogy to study the first damped frequency of a miniature loudspeaker used for cellular phones. Using the analogy approach, the authors derive an explicit formulation for the sound-pressure-level of a typical miniature loudspeaker of dynamic type. The veracity of the derived formulation is verified by comparing with the experimental result recorded by B and K apparatus. The derived formulation is further simplified by neglecting factors that are either irrelevant or insignificant for the first damped frequency. Through basic algebraic and calculus operations, this article also presents an explicit form of the first damped frequency. This work has laid the platform for engineers to tailor the design in pursuit of improving the performance of miniature loudspeakers.

High-capacity driven pipe piles have recently been shown to be a viable alternative to pile groups in terms of economy and strength. A complication has emerged for the construction of bridge foundations with large-diameter pipe piles, however–-the injury and mortality of fish from sound pressure waves produced from pile driving, otherwise known as barotrauma. Even though this issue has been prevalent in California, regulators have started to restrict other states. This has caused confusion as to how to avoid unexpected increases in construction costs while following environmental laws. After several trials, California Department of Transportation (Caltrans) engineers have implemented solutions to this problem, including driving windows, cofferdams, and a few different versions of air bubble curtains. This paper presents an accumulation of knowledge from engineers, biologists, and sound experts. It is to serve as an avenue for informing those who may soon be affected with pile-driving and fish barotrauma issues to minimize harmful effects and costs in the future.

This article explains the use of data acquisition in different fields of work apart from engineering. The article also presents a case study to research on disease transmission. A step-by-step feeding chart gives researchers an obvious way to see exactly how and when the disease is transferred, a crucial tool they can use in their quest to end that point of contact. In another case study, a piano maker is gathering waveforms with data acquisition hardware and software, but to a much different end. Sound engineers at Czech piano maker Petrof use an extensive acoustic measurement system to assure that the sound quality of Petrof pianos is top of the line. Many manufacturers turn to personal computers running Windows software. Petrof engineers got around the problem by implementing data acquisition hardware that lets them collect data continuously and interpret it in tandem in accompanying software. They use hardware from Microstar Laboratories of Bellevue, Washington, and MATLAB visualization software from MathWorks in Natick, Massachusetts.

Most of the sound quality evaluation methods for loudspeaker are based on physical evaluation and subjective evaluation. In the physical evaluation, we focus on the peak sound pressure and the rise speed. In the subjective evaluation, the sound quality is evaluated by the subjective evaluation experiment using the sound quality evaluation word. However, it's difficult for people who don't have professional knowledge in the field of acoustics to judge the performance of a loudspeaker from these evaluation methods. In addition, according to the engineers of a speaker manufacturer, the difference of the sound quality of the loudspeaker may affect the movement and motivation of the game. In this study, aims to evaluate the sound quality of loudspeaker objectively from a new point of view. In order to clarify whether the difference of the sound quality of the loudspeaker affects the movement, the movement analysis using OpenPose was carried out. As a result, it was found that the complicated motion was not likely to be affected by the difference of the sound quality of the loudspeaker. However, the results suggested that simple and familiar actions may be affected by the difference in loudspeaker sound quality.

Road noise is one of the dominant contributions to a vehicle interior noise when driving below highway speed. In this paper, we present the process we developed to support automotive OEMs with road noise engineering during vehicle design and development. The process allows to auralize, in a driving simulator for NVH, road noise CAE simulation results obtained from coupled multibody, structural finite-elements and acoustic models. With this process, engineers can now listen to a vehicle sound and perform interactive sound quality evaluation for road noise even before physical prototypes are available.

Reel-to-reel magnetic tape recording has a unique and specific sound which is highly sought after by music recording engineers. This talk will discuss the use of physical modelling signal processing to create algorithms which can emulate the sound of any reel-to-reel tape recorder, including ones which may not actually exist in the real world. These algorithms are designed to be used in modern music production software, meaning that they must be able to process audio in real-time with minimal latency, and offer interactive controls to the end user.

Full textAbstract:
The Makers Marks Collaborative, an international team of glass artists, visual designers, composers, and engineers, embarked on a project together from 2015–2016 to use the glassmaking studio as a staging ground for interdisciplinary, collaborative making. The team aimed to capture and preserve the sounds of traditional studio glassmaking, and then to share them outside the workshop domain through digital technologies and glass art objects. The goal was also to fulfill a public engagement grant from the Royal Academy of Engineering to highlight the engineering through the art and the engineers’ vision within the art making. The team recorded and isolated the unique sounds of the glassblowing process and its studio environment, and then used the resulting digital sound collection as the foundation for developing artistic outputs: a virtual instrument library, a glass object-instrument of performance, a series of glass objects translating selected virtual instruments, and a music composition. They questioned the nature and materiality of glass through dialogue between media and conversation among team members, while exploring the practice-based research question: “How can we embed our recorded sounds of the glassmaking process back into the glass itself?” This paper focuses on the collaborative, interdisciplinary making process of the team, the project outputs, and the metaphorical language that was a key process facilitation tool.

Full textAbstract:
This article proposes a contextualist approach to machine learning and aesthetics, using LANDR, an online platform that offers automated music mastering and that trumpets its use of supervised machine learning, branded as artificial intelligence (AI). Increasingly, machine learning will become an integral part of the processing of sounds and images, shaping the way our culture sounds, looks, and feels. Yet we cannot know exactly how much of a role or what role machine learning plays in LANDR. To parochialize the machine learning part of what LANDR does, this study spirals in from bigger contexts to smaller ones: LANDR’s place between the new media industry and the mastering industry; the music scene in their home city, Montreal, Quebec; LANDR use by DIY musicians and independent engineers; and, finally, the LANDR interface and the sound it produces in use. While LANDR claims to automate the work of mastering engineers, it appears to expand and morph the definition of mastering itself: it devalues people’s aesthetic labor as it establishes higher standards for recordings online. And unlike many other new media firms, LANDR’s connection to its local music scene has been essential to its development, growth, and authority, even as they have since moved on from that scene, and even as the relationship was never fully reciprocal.

This paper is intended as a brief basic primer on tire–pavement noise generation and measurement. It is particularly directed toward pavement and materials engineers who are aware that noise is an issue of concern to the public but have not been able to invest the time needed to investigate and learn about noise control fundamentals. This paper defines sound and noise, illustrates the public's growing awareness of noise issues, explains the units of measurement and measurement techniques, outlines some of the mechanisms of noise generation at the tire–pavement interface, and briefly discusses how pavements can help to mitigate noise problems. Significant progress has been made to reduce tire–pavement noise, and, with more applications and an increased understanding of noise generation and propagation, economical pavements are possible that control noise while maintaining safety and durability.

Full textAbstract:
There are several established procedures and design tools for estimating the background sound levels from heating, ventilation and air-conditioning (HVAC) building systems. Building Information Modeling (BIM) is a process commonly used in architecture, engineering, and construction that uses data to generate digital representations of a building’s physical and functional characteristics. We will demonstrate a BIM-automated design tool which uses a Dynamo script and a Revit model duct layout to estimate HVAC noise levels in buildings. With just a few inputs in the model, the script calculates the sound attenuation of each duct element and receiver room sound correction to estimate the HVAC background sound level in any space or building type. Leveraging existing data through BIM automation can help create efficient, optimized designs and improve coordination between mechanical engineers, architects, and acoustical consultants to meet acoustical design criteria.

Full textAbstract:
This paper presents a new technology that enables one to locate multiple sound sources with very a large dynamic range simultaneously, including very low frequency and negative signal-to-noise ration sound sources in a non-ideal environment, where there are random background noise and unknown interfering signals. In particular, spatial resolution of source localization is frequency independent. In other words, spatial resolution remains very high at very low as well as at very high frequencies. The underlying principle of this new technology is a hybrid methodology that includes a passive SODAR (nic etection nd anging), advanced signal processing and least-squares minimization. Using this technology, engineers will be able to visualize sound sources in both real time and post processing in an adversary test environment. Live videos of sound sources localization inside a crowd machine shop are shown, where there are unknown background noise, unspecified sound reflections and reverberation, and interfering signals.

The San Francisco Conservatory of Music (SFCM) Bowes Center is a complex, vertical building housing SFCM's performance, rehearsal, instruction, and dormitory spaces. Coordination issues during design and construction that are not strictly acoustical but that are critical to achieving the floating floor's optimum sound and impact isolation performance are discussed. This paper examines issues from early design to construction phases applicable to many types of floating floor systems, such as: setting structural point loading criteria, developing a sound isolation envelope, coordination with audiovisual (AV) and theater consultants with respect to routing of conduits and locating recessed AV boxes in floating floor, coordination with the architect and structural engineer to identify high point loads on floating floor, consideration of seismic restraint elements, structural coordination to evaluate anchorage needs for elements supported on floating floor, construction sequencing coordination with pre-construction contractor with respect to anticipated needs for lifts on raised floating floors, and coordination of floating floor shop drawings with framing shop drawings for elements supported from the floating floor. This project case study outlines a useful list to help architects, consultants, and engineers navigate the complex and varied coordination issues that may arise on projects with concrete floating floors.

Full textAbstract:
Building occupants rely on heating, ventilation, and air conditioning (HVAC) units for comfort. Chillers are HVAC units that serve the purpose of cooling a building. Because chillers are often placed on top of or near the building, the noise from the chiller can adversely affect the occupants. A crucial component of all chillers, the compressor, is responsible for the majority of the noise produced by the chiller. In addition to designing for cooling efficiency, engineers must also consider how quiet and acoustically efficient a chiller is. In this project, we aim to develop an enclosure to house the compressor, therefore, reducing the magnitude of noise that is emitted. We begin by studying an empty cavity model in an acoustical software and observing its modes, resonant frequencies, and corresponding pressure distributions. Next, we placed a sound source within the cavity and then analyzed the acoustics frequency response of the cavity without and with a sound-absorbent material. We then proceeded to analyze a FEM model of the compressor and its dynamic frequency response due to the bearing force. After further analysis of the compressor sound emission, simulations will be made for the compressor with the designed enclosure and sound-absorbent material.

AbstractConsidering transformation processes within organizations, reflection is an enabler for learning and adaption of engineering processes, methods, and tools. Moreover, reflection as a core element of agile engineering approaches. However, a sound understanding of reflection behaviors of engineers or engineering teams is lacking. In this paper we proposed a structured reflection procedure including different dimensions to reflect on. To analyse reflection behavior of engineers and engineering teams we propose a coding scheme comprising of nine behaviors. The coding scheme allows to evaluate the reflection behavior in real time and give feedbacks to improve the quality of reflection. The proposed coding scheme is initially tested within a workshop with industry partners.

Full textAbstract:
Traditionally, moral rights have not extended to the creators of sound recordings under either common law or civil law systems. The somewhat outdated rationale of this exclusion of sound recordings from the ambit of moral rights protection was generally that sound recordings were merely mechanical reproductions of already existing musical works, and hence the recordings lacked sufficient creativity to make them worthy of moral rights protection. In 1996, the WIPO Performances and Phonograms Treaty sought to remedy this anomaly in copyright law by extending the moral rights of paternity and of integrity to performers whose performances are fixed in sound recordings.This paper argues that New Zealand should follow WIPO's lead and extend the moral rights provisions of the Copyright Act 1994 to sound recordings. The author argues that sound recordings are imbued with sufficient creativity to merit moral rights protection and that this protection should be granted not only to performers but to sound engineers and producers, who also contribute creatively to the recording. This paper examines how moral rights in relation to sound recordings might work in practice and what remedies should be available for breach of these rights. The author concludes that the extension of moral rights to sound recordings need not impact detrimentally on the music industry, as some commentators fear.

Full textAbstract:
Traditionally, locomotive engineers begin sounding the train horn approximately one-quarter mile from the crossing to warn motorists and pedestrians approaching the intersection. To be heard over this distance, the train horn must be very loud. This combination of loud horns and the length along the tracks that the horn is sounded creates a large area adversely impacted by the horn noise. In urban areas, this area likely includes many nearby residents. The automated-horn system provides a similar audible warning to motorists and pedestrians by using two stationary horns mounted at the crossing. Each horn directs its sound toward the approaching roadway. The horn system is activated using the same track–signal circuitry as the gate arms and bells located at the crossing. Once the horn is activated, a strobe light begins flashing to inform the locomotive engineer that the horn is working. Horn volume data collected near the crossings clearly demonstrate the significant reduction of land area negatively impacted by using the automated horns. Residents overwhelmingly accepted the automated-horn systems and noted a significant improvement in their quality of life. Motorists preferred the automated-horn systems, and locomotive engineers rated these crossings slightly safer compared with the same crossings in the before (train horn) condition.

Sound legal decision-making frequently requires the assistance of scientists and engineers. The survey we conducted with the cooperation of the American Academy examines the views of the legal system held by some of the nation's most distinguished scientists and engineers, what motivates them to participate or to refuse to assist in lawsuits when asked, and their assessment of their experiences when they do participate. The survey reveals that a majority of the responding scientists and engineers will agree to participate when asked, and when they turn down requests, the most common reasons are lack of time and absence of relevant expertise. Dissatisfaction with legal procedures is also a deterrent, but our respondents indicated that some procedural changes would make their participation more likely. In addition, participation appears to be associated with a greater belief in the ability of the legal system to deal well with scientific matters.
