The optimization of modal spacing within small rooms (2008)
Presentation / Conference
Wankling, M., & Fazenda, B. (2008, November). The optimization of modal spacing within small rooms. Presented at Computing and Engineering Annual Researchers' Conference 2008, Huddersfield

The reproduction of audio in small rooms is significantly affected by room modes – resonant frequencies set up as a result of the geometry of the room. These frequency specific modes combine to form a unique frequency response for that room. This fre... Read More about The optimization of modal spacing within small rooms.

Acoustic diagnosis of driving belt physical condition in enclosures (2008)
Presentation / Conference
Fazenda, B., Gu, F., Ball, A., & Gilkes, O. (2008, October). Acoustic diagnosis of driving belt physical condition in enclosures. Presented at Internoise 2008, Shanghai, China

Timing belt transmission is a key subsystem of international combustion engines. Faults in such belt systems lead to power loss, increased emissions and, in case of failure, may even cause severe damage to the whole engine. Hitherto, the physical con...

Optimal modal spacing and density for critical listening (2008)
Presentation / Conference
Fazenda, B., & Wankling, M. (2008, October). Optimal modal spacing and density for critical listening. Presented at 125th Audio Engineering Society Convention, San Francisco, CA, USA

This paper presents a study on the subjective effects of modal spacing and density. These are measures often used as indicators to define particular aspect ratios and source positions to avoid low frequency reproduction problems in rooms. These ind...

3-Dimensional room impulse response measurements in critical listening spaces (2008)
Presentation / Conference
Romero Perez, J., & Fazenda, B. (2008, January). 3-Dimensional room impulse response measurements in critical listening spaces. Presented at Institute of Acoustics

Most of the knowledge and the existing objective acoustic measures defined to describe the sound field in large spaces are commonly evoked to predict the acoustic performance of small rooms. It is now becoming evident that this practice leads to flaw... Read More about 3-Dimensional room impulse response measurements in critical listening spaces.

Accurate sound source localization in a reverberant environment using multiple acoustic sensors (2008)
Journal Article
Atmoko, H., Tan, D., Tian, G., & Fazenda, B. (2008). Accurate sound source localization in a reverberant environment using multiple acoustic sensors. Measurement Science and Technology, 19(2), https://doi.org/10.1088/0957-0233/19/2/024003

This paper introduces a new method for the estimation of sound source distance and direction using at least three microphone sensors in indoor environments. Unlike the other methods that normally use approximations in obtaining the time difference be...
