Perception of soundscapes : an interdisciplinary approach (2012)
Journal Article

This paper takes an overall view of findings from the Positive Soundscape Project, a large inter-disciplinary soundscapes study. Qualitative fieldwork (soundwalks and focus groups) have found that soundscape perception is influenced by cognitive effe...

Perception of modal distribution metrics in critical listening spaces - dependence on room aspect ratios (2005)
Journal Article
Fazenda, B., Avis, M., & Davies, W. (2005). Perception of modal distribution metrics in critical listening spaces - dependence on room aspect ratios. Journal of the Audio Engineering Society, 53(12), 1128-1141

The subjective significance of two general types of metrics used to describe the "quality" of a room based on its aspect ratio are compared. Tests were carried out to evaluate differences between three virtual rooms that score extreme classifications...

Perception of reverberation time in small listening rooms (2002)
Journal Article
Niaounakis, T., & Davies, W. (2002). Perception of reverberation time in small listening rooms. Journal of the Audio Engineering Society, 50(5), 343-350

The perceptibility of small changes in reverberation time (RT) when music is reproduced within small studio control rooms was judged by a number of subjects. The aim of the study was to determine the difference limen (DL) for midfrequency RTs shorter... Read More about Perception of reverberation time in small listening rooms.

Hearing loss in the built environment : the experience of elderly people (2001)
Journal Article
Davies, W., Cox, T., Kearon, A., Longhurst, B., & Webb, C. (2001). Hearing loss in the built environment : the experience of elderly people. Acta acustica united with Acustica, 87(5), 610-616

A qualitative social survey has been conducted on a group of 207 elderly people with a hearing loss. The aim of the study was to determine the extent to which acoustic problems in the built environment affect this subject group. The project was thoug...

Response to "comment on 'reducing seat dip attenuation'" J. Acoust. Soc. Am. 110, 1260 (2001) (2001)
Journal Article

This letter responds to Klepper's comments [J. Acoust. Soc. Am. 110, 1260 (2001)] on the subject paper, which is concerned with ameliorating seat dip attenuation in auditoria by introducing a pit under the seats. Klepper asks what the effect of the p...

Reducing seat dip attenuation (2000)
Journal Article
Davies, W., & Cox, T. (2000). Reducing seat dip attenuation. ˜The œJournal of the Acoustical Society of America (Online), 108(5), 2211-2218

Strategies fur reducing seat dip attenuation in concert halls are considered. It is shown that the dip is established 4 ms after the direct sound from the stage arrives at the listener. Sound scattered from the seats and floor is the main cause of th... Read More about Reducing seat dip attenuation.

Subjective perception of seat dip attenuation (1996)
Journal Article

An investigation has been conducted into the subjective perception of the seat dip effect (a low-frequency attenuation affecting sound travelling at grazing incidence over seating). In a realistic simulation of a concert hall sound field, the thresho... Read More about Subjective perception of seat dip attenuation.

New attributes of seat dip attenuation (1994)
Journal Article

New measurements have been made on the low-frequency attenuation of an impulse excitation over-seating in an unoccupied concert hall and on scale model seats. Two new attributes of the phenomenon were found the attenuation varied over time and the wi... Read More about New attributes of seat dip attenuation.

Measuring auditorium seat absorption (1994)
Journal Article

There is a need for a more accurate laboratory measurement method to predict auditorium seat absorption. The traditional method tends to overpredict the absorption of the exposed front and sides of seating blocks. An alternative reverberation chamber...

Predicting theater chair absorption from reverberation chamber measurements - comment (1993)
Journal Article

The relationship between the measured acoustic absorption coefficient of an array of theater chairs and the ratio of the perimeter length to plan area of the array is considered. It is shown that the linear relationship measured by Bradley in a rever... Read More about Predicting theater chair absorption from reverberation chamber measurements - comment.

The sensitivity of listeners to early sound field changes in auditoriums (1993)
Journal Article
Cox, T., Davies, W., & Lam, Y. (1993). The sensitivity of listeners to early sound field changes in auditoriums. Acta acustica united with Acustica, 79(1), 27-41

The sensitivity of listeners to small changes in the early sound field of auditoria has been measured. This was done using a realistic artificial simulation system of a concert ball sound field. The simulation system was designed so that standard obj... Read More about The sensitivity of listeners to early sound field changes in auditoriums.
