The paper presents the results of the investigations of the underwater ship noises in coastal zone. The signal was measured in frequency band covering rang e from 5 Hz to 12 kHz: lt was investigated in different frequency bands. The method of signal analysis has been described in this paper. The results of investigations of average pressure spectrum of ambient noise and average pressure spectrum of ship noise in the frequency band from 5 H; to 1000 H: and the frequency band from 200 H; to 1000 H; have been presented. Moreover the sound pressure levels as a function of ship speed have been studied.
