STRUCTUREBORNE SOUND TRANSMISSION IN SHIPS

Model experiments have been carried out to investigate the influence of different structural details on the total vertical transmission of noise in a ship's hull from the machinery spaces to cabins on the upper decks. The model is an idealised 1:5 replica of a cross-section through the engine room, casing and deckhouse of a 50,000-dwt bulk carrier, conventionally built with deckhouse above the engine room. Six built-up stages have been investigated, each stage corresponding to a different transmission path connecting tanktop and main deck. Preliminary results indicate that the build-up of the structure does not affect the structure-borne transmission through the hull to any great extent because of the greater contribution of longitudinal waves.
