A transient boundary element method model of Schroeder diffuser scattering using well mouth impedance (2008)
Journal Article
Hargreaves, J., & Cox, T. (2008). A transient boundary element method model of Schroeder diffuser scattering using well mouth impedance. ˜The œJournal of the Acoustical Society of America (Online), 124(5), 2942-2951. https://doi.org/10.1121/1.2982420

Room acoustic diffusers can be used to treat critical listening environments to improve sound quality. One popular class is Schroeder diffusers, which comprise wells of varying depth separated by thin fins. This paper concerns a new approach to ena...

Monaural room acoustic parameters from music and speech (2008)
Journal Article
Kendrick, P., Cox, T., Li, F., Zhang, Y., & Chambers, J. (2008). Monaural room acoustic parameters from music and speech. ˜The œJournal of the Acoustical Society of America (Online), 124(1), 278-287. https://doi.org/10.1121/1.2931960

This paper compares two methods for extracting room acoustic parameters from reverberated speech and music. An approach which uses statistical machine learning, previously developed for speech, is extended to work with music. For speech, reverberatio...

Internet and mobile technologies for a public role in noise surveying (2008)
Presentation / Conference
Mydlarz, C., Drumm, I., & Cox, T. (2008, June). Internet and mobile technologies for a public role in noise surveying. Poster presented at Paris ASA Conference, Paris, France

The traditional method of noise surveying is to use trained professionals to go to a specific site to measure and assess noise levels using dedicated and expensive equipment. This project aims to enfranchise the public by providing them with the oppo... Read More about Internet and mobile technologies for a public role in noise surveying.

Involving the public in noise surveys via mobile technology (2008)
Presentation / Conference
Mydlarz, C., Drumm, I., & Cox, T. (2008, April). Involving the public in noise surveys via mobile technology. Presented at IOA Spring Conference 2008, Reading, UK

The IMPRINtS project (Internet and Mobile technologies for a Public Role In Noise Surveying) aims to enable and encourage public participation in a large-scale environmental noise survey. The primary objective of this work is to raise public awarenes... Read More about Involving the public in noise surveys via mobile technology.

Lüke and power residue sequence diffusers (2008)
Journal Article
Dadiotis, K., Angus, J., & Cox, T. (2008). Lüke and power residue sequence diffusers. ˜The œJournal of the Acoustical Society of America (Online), 123(4), 2035-2042. https://doi.org/10.1121/1.2885761

Conventional Schroeder diffusers have been successfully used for many years. However, their frequency range is limited by the flat plate effect that occurs when all the wells radiate in phase. This occurs at harmonics of p times the design frequency... Read More about Lüke and power residue sequence diffusers.

A combined blind source separation and adaptive noise cancellation scheme with potential application in blind acoustic parameter extraction (2008)
Journal Article
Zhang, Y., Chambers, J., Kendrick, P., Cox, T., & Li, F. (2008). A combined blind source separation and adaptive noise cancellation scheme with potential application in blind acoustic parameter extraction. Neurocomputing, 71(10-12), 2127-2139. https://doi.org/10.1016/j.neucom.2007.09.019

Room acoustic parameters such as reverberation time (RT) can be extracted from passively received speech signals by certain ‘blind’ methods, thereby mitigating the need for good controlled excitation signals or prior information of the room geometry....

The photo‐survey research method : capturing life in the city (2008)
Journal Article
Moore, G., Croxford, B., Adams, M., Refaee, M., Cox, T., & Sharples, S. (2008). The photo‐survey research method : capturing life in the city. Visual Studies, 23(1), 50-62. https://doi.org/10.1080/14725860801908536

Recent promotion of city centre living within UK policy has led to a commensurate interest in city centre conditions and the opinions and experiences of the people who live there. An apposite, straightforward method to capture city centre residents'... Read More about The photo‐survey research method : capturing life in the city.

Acoustics of activated carbon (2008)
Thesis
Bechwati, F. Acoustics of activated carbon. (Thesis). Salford : University of Salford

This thesis describes a study into how sound interacts with activated carbon, a material that
exhibits adsorbing and desorbing properties. Adsorption is where molecules from the
surrounding gas are attracted to the material microstructure and hel... Read More about Acoustics of activated carbon.

A time domain boundary element method for compliant surfaces (2008)
Presentation / Conference
Hargreaves, J., & Cox, T. (2008, January). A time domain boundary element method for compliant surfaces. Presented at EURONOISE, the 155th ASA Meeting, and the 9th Congrès Français d'Acoustique, Paris, France

The best way of representing compliant surfaces in time domain prediction models, such as the transient Boundary Element Method (BEM), is currently unresolved. This is not true of frequency-domain, time-invariant models, where the common practice is... Read More about A time domain boundary element method for compliant surfaces.
