Broadband sound reflection by plates covering side-branch cavities in a duct

When a segment of a rigid duct is replaced by a plate backed by a hard-walled cavity, grazing incident sound waves induce plate bending, hence sound reflection. The mechanism is similar to the drumlike silencer with tensioned membranes [ L. Huang , J. Acoust. Soc. Am. 112 , 2014-2025 ( 2002 ) ]. How...
