Sound insulation of plenum windows installed with rigid cylinder array (2019)
Conference Proceeding
Li, X., & Tang, S. K. (2019). Sound insulation of plenum windows installed with rigid cylinder array. In Proceedings of inter-noise 2019. The 48th International Congress and Exhibition on Noise Control Engineering

In this study, a 1:4 scale down model was established to investigate the acoustical performance of plenum window installed with a rigid cylinder array. A total of 6 rigid cylinders were vertically placed as a 2x3 array inside the central cavity of a... Read More about Sound insulation of plenum windows installed with rigid cylinder array.

Effects of sound incidence angle on the effectiveness of noise reduction measures applied to acoustic windows (2019)
Conference Proceeding
Leung, M., Tang, S. K., & Fung, M. L. (2019). Effects of sound incidence angle on the effectiveness of noise reduction measures applied to acoustic windows. In Proceedings of inter-noise 2019 : the 48th International Congress and Exhibition on Noise Control Engineering

With more residential buildings being built close to road network systems in Hong Kong, there is an increasing need to find method to combat excessive traffic noise exposure in residentials unit. Several measures have been employed in various places,... Read More about Effects of sound incidence angle on the effectiveness of noise reduction measures applied to acoustic windows.

Insertion loss of asymmetrical balconies on a building facąde (2019)
Journal Article
Tang, S. K., Ho, C. Y., & Chan, W. Y. (2019). Insertion loss of asymmetrical balconies on a building facąde. The Journal of the Acoustical Society of America, 146(3), 1580-1594. https://doi.org/10.1121/1.5125135

The acoustical insertion loss of asymmetrical balconies on high-rise buildings was studied experimentally using a 1:3 scaled down model in the present study. Four balcony forms featured by the presence of a full-height side-wall were included. A line... Read More about Insertion loss of asymmetrical balconies on a building facąde.

Active cancellation of sound generated by finite length coherent line sources using piston-like secondary source arrays (2019)
Journal Article
Hu, Q., & Tang, S. K. (2019). Active cancellation of sound generated by finite length coherent line sources using piston-like secondary source arrays. The Journal of the Acoustical Society of America, 145(6), 3647-3655. https://doi.org/10.1121/1.5112761

The active cancellation of the sound generated by finite length coherent line sources is investigated numerically in the present study. A secondary source consists of a central circular core enclosed within an annulus is proposed. It is demonstrated...

Empirical prediction of traffic noise transmission loss across plenum windows (2019)
Journal Article
Li, X., Tong, Y. G., Tang, S. K., & Lau, K. K. (2019). Empirical prediction of traffic noise transmission loss across plenum windows. Applied acoustics. Acoustique appliqué. Angewandte Akustik, 151, 45-54. https://doi.org/10.1016/j.apacoust.2019.03.004

A parametric study on the traffic noise transmission loss across plenum windows was carried out experimentally in this investigation in an attempt to establish a simple empirical model for predicting this transmission loss. A total of fourteen full s... Read More about Empirical prediction of traffic noise transmission loss across plenum windows.
