Numerical Design of Sound-Insulating Material with Combined Cavities of Mixed Sizes

Shock and Vibration, 2020
In view of the low-frequency acoustic insulation performance and poor pressure resistance of a single cavity at present, finite element software COMSOL is used to establish an analysis model to calculate the sound transmission loss (TL) and compression ...

Partition intersections and their effects on transmission loss and apparent sound transmission class [PDF]

Proceedings of Meetings on Acoustics, 2013
It is widely recognized and accepted that poorly designed intersections between partitions can significantly reduce the sound isolation that is achieved. However, the effect of specific intersection details are not widely reported and available. This presentation will focus on a case study in which different intersection details have been tested in the
