Description
Summary:During the course of measuring the transmission of sound through small cavity-backed panels, an apparent contradiction between measurement and simple theory was found at the fundamental resonant condition for the model under test. An attempt is made to clarify the apparent inconsistency between the simple theory and measurements, and to draw attention to the possibility of substantial negative transmission loss. Experimental results imply that the damping constant of the panel/cavity resonance is equal to or greater than the acoustic radiation damping.
