Experimental study of different approaches for active control of sound transmission through double walls
Chaoying Bao,Jie Pan +1 more
TL;DR: In this paper, three different approaches for controlling sound transmission through double-panel partitions into a room, i.e., applying acoustic control sources in the air gap between the two panels (cavity control), applying vibration control sources on the radiating panel (panel control), and applying acoustic controlling sources in a receiving room (room control), are studied and compared to each other experimentally.
