MOBILITY/RADIATION FACTOR EVALUATIONS AS DESIGN AIDS FOR HIGH PERFORMANCE VEHICLES
Traditionally for surface craft, the noise control engineer has relied on standard airborne and structureborne noise surveys to identify and isolate vibro-acoustic deficiences. However, the increased performance standards of modern vehicles have restricted design alternatives so that additional information is required to further categorize deficient structural elements. The paper describes mobility methods which offer a means of obtaining this information when used in conjunction with associated radiation factor measurements. The potential of these methods is illustated by application to an airborne noise problem observed in the cabin of a small naval landing craft at cruising speed. Order from: BSRA as No. 48,449.
