Architectural acoustics not only covers buildings and the environment around them but also human perception of the acoustic environment, indoors and outdoors. As a technical committee of the acoustical society, our members are spread over research, academia, practitioners and industry. Architectural acoustics is not reserved for concert halls and opera houses but applies to all occupied spaces and has a direct impact on quality of life of any user of the space. Specific topics within the discipline include but are not limited to environmental sound, speech privacy, and speech intelligibility,

Active Acoustics systems can be thought of as reducing the effective absorption of a room and/or increasing its effective volume and depend upon well-designed acoustic treatment and room shaping. Because Active Acoustics systems cannot reduce HVAC noise or improve isolation, these associated acoustical properties depend on the room’s acoustical design. Therefore, a successful Active Acoustic system installation relies on coordination with the acoustical consultant, from conceptual design to scheduling initial rehearsals with the various performance groups that utilize the room.

Changes in both the ice cover and ocean stratification have significant implications for acoustic propagation and ambient sound. The Arctic is not done changing, and papers in this special issue, therefore, represent a snapshot of current acoustic conditions in the Arctic.

Previous studies have discussed six pre-Sabine quantifiable guidelines employed in room acoustic design: voice directivity, audience rake, “echo theory”, stage acoustics, reverberation, and length, width, and height ratios. Around the turn of the 18th century, these notions led to two shapes that were theoretically regarded optimal for rooms with acoustical demands: ellipse and semi-circle. The first of these shapes to be tested was the ellipse in the design for the Iffland Theatre (1802–1817).

Acoustics is the study of small pressure waves or sound waves in air which can be detected by the human beings. The scope of acoustics is not limited and extended to lower and higher frequencies ultrasound and infrasound. Acoustics now includes Structural vibrations and perception travelling of sound is an area of acoustical research, for research purposes acoustics are considered, the propagation fluids like air and water. In such a case acoustics is a part of fluid dynamics. The outmost problem of fluid dynamics is that, the equations of motions are non linear and this implies that an exact

The ISO 22955 standard " Acoustic quality of open plan offices " was published in may 2021. It aims to provide principles, descriptors, and measurement methods to characterize acoustics, which are easy to use and correspond to the perception of the acoustical environment by the occupants of the spaces. The scope of the standard is the acoustics of open-plan offices and, more specifically, cognitive effects of noise, i.e. acoustic comfort and noise disturbance in association with the activity. After more than a year of use of the standard, this document proposes to take stock of it and to ident

Acoustics, an age-old field of study, has recently revealed new physics with new degrees of freedom of wave propagation. These new findings are invaluable for information processing using acoustic modality. Information processing using acoustics is called acoustic computing. Computing Boolean algebra, which has already been demonstrated, could pave the pathways even for quantum computing using acousti

Worship space acoustics have been established as an important part of a nation’s cultural heritage and area of acoustic research, but more research is needed regarding the region of northern Europe. This paper describes the historical acoustics of an important abbey church in Sweden in the 1470s. A digital historical reconstruction is developed. Liturgical material specific to this location is recorded and auralized within the digital reconstruction, and a room acoustic analysis is performed. The analysis is guided by liturgical practices in the church and the monastic order connected to it. I

Musical acoustics was launched as one of the first Technical Committees of the Acoustical Society of America. The Technical Committee in Musical Acoustics (TCMU) is concerned with applying science and technology to the field of music. The four main areas are (1) physics of musical sound production in musical instruments and the voice, (2) music perception and cognition, (3) analysis and synthesis of musical sounds and compositions, and (4) recording and reproduction technology. The scopes of areas have changed over time; for example, current interests in using groundbreaking methods in artific

Abstract Active- and passive-acoustic methods are widely used tools for observing, monitoring, and understanding marine ecosystems. From 25 to 28 May 2015, 214 scientists from 31 nations gathered for an ICES symposium on Marine Ecosystem Acoustics (SoME Acoustics) to discuss three major themes related to acoustic observations of marine ecosystems: (i) recent developments in acoustic and platform technologies; (ii) acoustic characterisation of aquatic organisms, ecosystem structure, and ecosystem processes; and (iii) contribution of acoustics to integrated ecosystem assessments and management.

The Immersive Media Lab at McGill University hosts a Virtual Acoustics Technology (VAT) system incorporating a suspended array of omnidirectional loudspeakers. Using a convolution reverb engine, acoustic simulations of real spaces can be realized via a catalog of Room Impulse Response measurements. Reflected sound in the room helps to disguise the location of the sound emitters rendering virtual acoustics. One limitation of the system, however, is the interference between the lab’s natural acoustics and the virtual environment generated by the VAT system. The improvement under consideration is

Exploring acoustic space, this article aims to supplement the practice of acoustic design by exposing other perspectives on sound’s relationship to space. Following Paul Carter’s notion of sonic ambiguity, the author contends that the idealized sonic image of acoustics eliminates the potentiality inherent to sound and listening as forces of relational intensity and differentiation. To draw out this tension, the article examines alternative forms of acoustics as appearing within the practice of sound art. Through eccentric and speculative design, sound art comes to demonstrate a vital addition

It could be divided into two main aspects: physical acoustics of the ear and physiological acoustics. In physiological acoustics, there are some common research methods, such as objective experimental testing, subjective feelings evaluation survey statistical method, building the physical acoustic model and numerical simulation methods, etc. The authors are researching the accurate mathematical model of equal loudness curves, critical ba
