Narrow sidebranch arrays for low frequency duct noise control (2012)
Journal Article
Tang, S. K. (2012). Narrow sidebranch arrays for low frequency duct noise control. The Journal of the Acoustical Society of America, 132(5), 3086-3097. https://doi.org/10.1121/1.4756951

The present study investigates the sound transmission loss across a section of an infinitely long duct where one or more narrow sidebranch tubes are installed flushed with the duct wall. The finite-element method is used to compute the wave propagati... Read More about Narrow sidebranch arrays for low frequency duct noise control.

A directionally tunable but frequency-invariant beamformer on an acoustic velocity-sensor triad to enhance speech perception (2012)
Journal Article
Wu, Y. I., Wong, K. T., Yuan, X., Lau, S. K., & Tang, S. K. (2012). A directionally tunable but frequency-invariant beamformer on an acoustic velocity-sensor triad to enhance speech perception. The Journal of the Acoustical Society of America, 131(5), 3891-3902. https://doi.org/10.1121/1.3701991

Herein investigated are computationally simple microphone-array beamformers that are independent of the frequency-spectra of all signals, all interference, and all noises. These beamformers allow the listener to tune the desired azimuth-elevation "lo...

Experimental investigation of the sound absorption performance of compartmented Helmholtz resonators (2012)
Journal Article
Tang, S. K., Ng, C. H., & Lam, E. Y. (2012). Experimental investigation of the sound absorption performance of compartmented Helmholtz resonators. Applied acoustics. Acoustique appliqué. Angewandte Akustik, 73(9), 969-976. https://doi.org/10.1016/j.apacoust.2012.03.016

An experiment was derived in the present study to investigate the effects of coupling up two Helmholtz resonators on their overall sound absorption performance. The effect of compartmenting the cavity of a resonator on its sound absorption property w...

Perception of urban park soundscape (2012)
Journal Article
Tse, M. S., Chau, C. K., Choy, Y. S., Tsui, W. K., Chan, C. N., & Tang, S. K. (2012). Perception of urban park soundscape. The Journal of the Acoustical Society of America, 131(4), 2762-2771. https://doi.org/10.1121/1.3693644

A number of studies have been initiated to explore how to improve the soundscape quality in urban parks. However, good soundscape quality in parks cannot be provided without a thorough understanding of the complex relationships among sound, environme...

On the study of the effects of sea views, greenery views and personal characteristics on noise annoyance perception at homes (2012)
Journal Article
Nang Li, H., Kwan Chau, C., Sze Tse, M., & Tang, S. K. (2012). On the study of the effects of sea views, greenery views and personal characteristics on noise annoyance perception at homes. The Journal of the Acoustical Society of America, 131(3), 2131-2140. https://doi.org/10.1121/1.3681936

Noise annoyance has caused significant adverse impacts on human beings and numerous efforts have been spent on mitigating annoyance problems. Natural greenery has been shown to be able to moderate annoyance problems at home but this conclusion was dr...
