Popis: | The wave motion within a cavity between two flexible walls is first investigated numerically. The results then form the basis for a new SEA formulation in which each element describe one kind of coupled cavity-wall wave motion. This formulation obsoletes the non-resonant transmission path commonly used in SEA of sound transmission and compared to classical formulations it improves results at frequencies around and a bit above the double wall resonance. The new formulation is compared to three sets of measurements found in the literature showing fair agreements. QS 2013 |
