Abstract

Infinite panel theory often simulates finite panel sound transmission loss (TL) quite accurately, even for panels with complex cross sections. This tutorial explains how to easily compute infinite panel TL for different angles of sound incidence. The tutorial also explains how to compute statistical averages of transmitted power due to impinging sound with random angles of incidence. Concepts like coincidence frequency, and its corresponding TL degradation; low-frequency mass law behavior; and the effects of adding damping to a structure are explained. Images of incident and radiated sound, along with panel vibrations, are used to illustrate the basic theory.
