In 1981, in order to reduce noise in the living quarters of the T. S. Seisui Maru, a soundproof compartment was built at the entrance to the engine rooom from the upper deck and the door was doubled. The noise level was measured before the reconstruction, and afterward studied the noise insulation effect in each compartment, the result was that the noise level reduced in each compartment by the extra door was only 1～2 dB ( A ). However in opening the doors one by one going in and out, the high pitched gas propagation waves that previously came from the engine room when the door was opened, no longer came out to the living quarters, and as result the noise level near the engine room could be constantly held below 80 dB ( A ). Thie shows that consideration of the movement of people on board when deciding the location and construction of compartment, can significantly affect noise insulation within the hull. This is a matter worth noting in designing a small vessel.
