Room acoustics for the aged

The Journal of the Acoustical Society of America, 1980
This article deals with the combined effects of noise and reverberation on the speech-reception threshold for sentences. It is based on a series of current investigations on: (1) the modulation-transfer function as a measure of speech intelligibility in rooms, (2) the applicability of this concept to hearing-impaired persons, and (3) hearing loss for ...

The acoustics of rooms [PDF]

Physics Education, 1967
The propagation of sound in rooms is discussed. Sabine's formula for reverberation time is derived as an approximation to Eyring's formula. The relation between optimum reverberation time and use of a room is considered. Finally, the investigation and treatment of an acoustically poor room are described, illustrating the improvement obtained by the use

Measurements in room acoustics

Journal of Sound and Vibration, 1964
Abstract This is the second of a group of three papers reviewing the field of room acoustics, and it concentrates on the measurements developed for evaluating the properties of halls and auditoria. Among the most important are absorption coefficients, reverberation time, frequency irregularity, and transient and directional response.

On the acoustics of operating rooms.

The Journal of the Acoustical Society of America, 2011
Designing modern operating rooms to meet al.l design criteria can be a challenge. Creating a sterile, well-lit, temperature and humidity appropriate environment for medical operations typically takes precedence over the acoustics of the operating room. The sterile, washable operating room surfaces are commonly hard and reflective, offering little sound

Fundamentals of room acoustics [PDF]

, 2004
A reverberation can be heard in an enclosed room if a sound source, which was in operation for a longer period, is suddenly turned off. Its duration depends on the room volume and the room’s interior design; the reverberation time is short in small rooms and in rooms which have large absorbing surfaces.

The Acoustics of Coupled Rooms

The Journal of the Acoustical Society of America, 1946
There are many examples of acoustically coupled rooms where ordinary reverberation formulas do not apply, for example: theaters, auditoriums, or churches connected to foyers, anterooms, hallways, or organ chambers. The theory of coupled rooms has been given by Davis and by Eyring based on the assumptions usually made in deriving reverberation-time ...

The acoustics of domestic rooms

Applied Acoustics, 1972
Abstract Octave-band reverberation time characteristics of fifty living-rooms and fifty kitchens are presented. The measurements were carried out using a portable cassette tape-recorder system which was shown to compare well with more sophisticated apparatus, although the portable system lacked dynamic response, especially in the high-frequency ...

Room Acoustics Simlation

2014
This chapter shows examples of numerical simulation results on various sound fields in the interior of buildings and vehicles, such as auditoria, large space with seating rows, reverberation rooms, vehicle cabins, and small space with partitions. In each section, the features and problems of each sound field are introduced, and numerical modeling ...
