In this paper an alternative procedure to vibro-acoustics study of beam-type structures is presented. With this procedure, it is possible to determine the resonant modes, the bending wave propagation velocity through the study of the radiated acoustic field and their temporal evolution in the frequency range selected. As regards the purely experimental aspect, it is worth noting that the exciter device is an actuator similar to is the one employed in distributed modes loudspeakers; the test…

Power flow in coupled bending and longitudinal waves in beams
TLDR
The measurement of power in both bending and longitudinal waves when both waves are present is demonstrated and the effect of coupling between waves at the junction in a T-beam is illustrated using results from measurements of power flow.
