Abstract:
An experiment was conducted in a shallow water region of the Mediterranean Sea to study wind-generated noise. In addition to measuring the noise field, propagation-loss data were collected and used in a detailed modelling of the environment. The environmental information was then used as input to a noise model based on wave theory that computes the noise field in the water column for a given unknown source strength. By comparing model predictions with data, the influence of the environment on recorded noise levels could be removed and a measure of the noise source spectrum levels obtained as a function of wind speed, which is the parameter that was determined to be more closely correlated to the noise level than is wave height.
