Abstract: Measurement of ambient noise during typhoon no. 10 (1984), passed by the west coast of KYUSYU, on frequencies from 4 Hz to 1000Hz were made in the New Mie Fishing Port of NAGASAKI. These results were compared with measurements in the New Mie Fishing Port and in the shallow water near Azisone during the moderate weather. During the moderate weather, the measured ambient noise spectra in the port was produced predominantly by marine life, and no noise was recorded from outside of the port due to the barrier provided by the sea wall and the shallow water. During the high-sea-state conditions of typhoon no. 10, the measured ambient noise levels were directly dependant on the wave conditions in the port, at the sea wall and at the mouth of the port. However, in the 4Hz-12.5Hz range, the noise levels included ambient noise from outside of the port' s sea wall. Changes of spectrum in the low frequency range (4Hz-12.5Hz) could be detected about 20 hours before the typhoon acutually hitted the port.
