A Study on the Application of Statistical Energy Analysis to Sound and Vibration Transmission

Abstract

In recent years, statistical energy analysis (SEA) is developed and used in studies on the transmission of sound and vibration through the structure of aircrafts, ships etc. In this paper, SEA is applied to the problem on a small steel structure system. Examinations are carried out using a small speaker set in the system and white noise power is supplied as a noise source. It is found that the reasonable evaluation of internal loss factor of panels composing the system is the key to the analysis and the usefulness of the application of SEA on the problem is confirmed by good agreement between theoretical results and experiments.
