INTERIOR NOISE CONTROL PANELS FOR A SURFACE EFFECT SHIP

An advanced ship design concept for the US Navy is for a twin-hull 80-knot destroyer type of aluminium construction propelled by a water jet. Preliminary design calculations had shown that the ship would be excessively noisy without noise control. The paper describes the noise control measures adopted which included the use of augmenting panels attached to compartment bulkheads and overheads. Brief design details of a structural bulkhead and an augmenting assembly are given and the results of acoustical testing of a number of configurations are presented. Correlation of the experimental data with theory gives a mixed degree of agreement. It is concluded that the type of augmenting panel developed is an effective measure for controlling compartment noise of weight critical ships.
