Damping Response Analysis of L-shaped Panel Structure with Partial Acoustic Black Hole in One Plate Edge

Abstract

This paper describes hybrid vibration analysis using Statistical Energy Analysis（SEA）and FEM for two panels connected in L-shape with an acoustic black hole having a damping layer. The size of acoustic black hole in the L-shaped panel structure is changed. We focused on effects of changing the size of the acoustic black hole in the L-shaped panel structure on wave transmission characteristics between the two panels and damping effects due to the acoustic black hole.
