Duct sound produced by vortex flow over a splitter plate (2022)
Journal Article
Tang, S. K. (2022). Duct sound produced by vortex flow over a splitter plate. Journal of Sound and Vibration, 541, Article 117352. https://doi.org/10.1016/j.jsv.2022.117352

This paper examines the sound generated by an inviscid low Mach number vortex filament as it moves near a semi-infinite splitter in a two-dimensional duct with and without vortex shedding at the splitter edge. A strong one-dimensional sound is produc... Read More about Duct sound produced by vortex flow over a splitter plate.

Roadway traffic sound measured up on a high-rise building - the sound-level's statistical normality (2022)
Journal Article

Percentile-value ceilings/thresholds have been mandated by governments around the world on roadway traffic sound-level. Such percentile values, by definition, change with the sound-level’s underlying probability distribution, i.e., the same percentil...
