AMBIENT NOISE STUDY - BIMINI, BAHAMAS.
Abstract
During an eighteen day period in March 1966, measurement of the ambient noise and in situ environmental parameters were sampled at 12 minute intervals off the coast of Bimini, Bahamas. There was no apparent correlation between the noise data at frequencies of 25 Hz and 100 Hz with wind speeds up to 25 knots or with wave heights up to 5 feet. At frequencies of 400 Hz and 1600 Hz, the ambient noise levels show a strong correlation with wind speed, and a weak correlation with wave height. Power spectral density analyses of the data showed common low frequency periodicities in the noise, wind speed and direction, and in current speed and direction. Higher frequency periodicities of 4 to 6 hours were present in the 400 Hz noise, and of 7 to 10 hours in the 100 Hz noise. These higher frequencies were not apparent in the environmental parameters.
