Abstract
This paper deals experimently with the difference between the cabins in ship-board and the reverberation chamber in sound transmission loss. Experimental results from the cabins show that there are various flanking transmission losses which deteriorate significantly the performance of the sound transmission loss. They also show that as a representative of the flanking transmission losses, sound leakages between a ceiling and a wall, the joints of the partitions, and the luminant devices play an important role. From the various measurements, it can be is concluded that unless one do not take any treatments on the flanking transmission loss, the field sound transmission loss will be considerably decreased by more than 10 dB, comparable to the sound transmission loss.
