Abstract:

“How to engineer a mood - A study of sound in audiovisual contexts” is a study on the perception of sound in audiovisual contexts, i.e. sound and the image combined. There seems to be a consensus among researchers in the field on the fact that music influences the interpretation on film. However, there does not seem to be a specific consensus in regards to other sounds than music, such as the human voice or sound effects. Guided by a set of theories, an audiovisual text will be analyzed, in part through results of a quasi-experimental pilot survey and partly by the author herself. This paper w

A bass enhancement technique using the missing fundamental called VBS is presented. There are Several different approaches for using VBS in different applications. The technique is most useful in speakers that has a poor low frequency capability. It is presented in this report how it can be used for mixing purposes. How can a mix engineer use this technique to get a more balanced mix in laptop speakers without sacrificing the balance in large loudspeakers and headphones? To investigate this question an A/B style listening test is conducted, where the subjects get to answer both quantitative an

Describing planned acoustic design by single number ratings yields a weak link to the subjective event, especially when the single number ratings are interpreted by others than experienced acousticians.

Realistic interactions with sound objects in video games are a contributing factor to the overall immersion. Car engine sound design is an area where the auditory feedback from driving would have an impact on that immersion. For this study, three methods for designing car engine sounds are evaluated. A traditional method in the game sound industry is to use several sampled audio recordings for the reproduction of engine sounds, which is in this study represented as a sample-based model. The sample-based model is evaluated together with a model using granular synthesis in an in-game scenario. A

This thesis contains original research into the propagation of sound in acoustically lined ducts with flow. The motivation for this work is the requirement to predict the sound attenuation of acoustic liners in the bypass duct of modern turbofan aeroengines. The liners provide the most effective means with which to suppress the rear fan noise. It is therefore important to make the best possible use of the available lined area by optimising the liner configuration.

Noise control and sound quality analysis are important, since noise has been registered to be a predominant factor in stress and a source of great annoyance. Traffic noise is a problem and a major part of this noise comes from heavy vehicles. The only legislative requirement for heavy-duty trucks regarding noise emissions, is that the noise level does not exceed an Aweighted sound pressure level of 80 dB. The specification of an A-weighted sound pressure level is, however, not an adequate description of psychoacoustic annoyance and therefore work towards defining a better description of loudne

Abstract:

This thesis is concerned with the development and application of laser induced thermal grating spectroscopy (LITGS) as a tool for thermometry in reacting and non-reacting flows. LITGS signals, which require resonant excitation of an absorbing species in the measurement region to produce a thermal grating, are acquired for systematic measurements of temperature in high pressure flames using OH and NO as target absorbing species in the burned gas. The signal obtained in LITGS measurements appears in the form of a time-based signal with a characteristic frequency proportional to the value or the

Eventhough the youth of today has an increasingly solid foundation in technology and foreign languages, they lack the interest in this industry since it requires a large amount of manual labor. As a result, the industry is facing an aging problem among its engineers as well as a reduction in computer literacy. Therefore, one should focus on the importance of engin

Abstract:

This legal policy thesis asks: Is sampling so inconsistent with copyright that it warrants a unique system? Sampling is the musical practice of arranging new recordings from existing recordings. Often, it conflicts with copyright, a legal system that aims to encourage progress and innovation, primarily by granting exclusive rights as incentives to create and distribute original works. Two countervailing positions in existing literature articulate the conflict between sampling and copyright. The first views sampling as an appropriative practice

Abstract:

This dissertation ethnographically represents the work of three live sound engineers and the profession of live sound reinforcement engineering in the New York City metropolitan area. In addition to amplifying music to intelligible sound levels, these engineers also amplify music in ways that engage the sonic norms associated with the pertinent musical genres of jazz, rock and music theater. These sonic norms often overdetermine audience members' expectations for sound quality at concerts. In particular, these engineers also work to sonically and visually mask themselves and their equipment. E

O trabalho de investigação musicológica apresentado nesta tese ocupa-se desse contexto, o qual carece, até ao momento, de um tratamento historiográfico aprofundado, que este trabalho procura concretizar.

Abstract:

Many structural acoustic and vibration designs rely extensively on materials that are light-weight, stiff, and highly damped. Advanced materials such as metallic foams can be engineered to achieve these properties in order to control sound and vibration for a variety of aerospace, maritime, and ground transportation applications. In this work, the structural and acoustic properties of commercially available and digitally designed metallic foams are analyzed through numerical and experimental methods. Furthermore as a post-manufacturing process, metallic foams can be engineered in order t

These vehicle types include whistling vehicles such as ambulances, fire engines and police cars, as well as cars, locomotives and buses that are not whistling vehicles. Most of the literature on general vehicle identification and whistle recognition uses more complex neural network algorithms, or images, for analysis, which require a large amount of computation.

In addition, a finite-element model of the engine was constructed via reverse engineering from a 3D scan. The main causes of engine vibration and noise were clarified and identified individually through the experiments and the engine model. Finally, a nano-emulsified diesel fuel was used for the eng

Principal component analysis (PCA) and linear discriminant analysis (LDA), which are two methods of feature extraction that reduce computational load, are used. Second, feature vectors are extracted using PCA, LDA and these data are used as the classifier input. The cl
