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.
