Abstract:

Research is concerned with studying the effect on overside noise of the interaction between the mechanical impedance characteristics of shipboard machinery and structure which supports it. Supporting structures are defined to include resilient mounting systems, fabricated substructures and foundations and various hull configurations. The equation and charts allow computation of the far-field sound pressure level patterns in the water for each of several possible modes of hull vibration and for frequencies below about 600 cps. The charts themselves consider only the half-space below the submarine however, the equations given are general and may be extended to the upper halfspace and also to higher frequencies. Author
