Analysis of Acoustic Baffles for Underwater Noise Reduction

Abstract

This is an interim report on the study of underwater noise reduction techniques being conducted by the Sperry Division. Included in this report is a description of the work being done on various types of acoustic baffles. The theoretical analysis of a multilayer cylindrical baffle is given; spring-mass type baffles are analyzed using a lumped-parameter approach. For both of these baffles, good agreement is obtained between analytical and experimental data. Also presented are both theoretical and experimental results of a new baffle material, Sonite, which shows promise of operating at deep depths without the need for pressure compensation.
