|Abstract:||This paper presents the results from an experimental work to characterize the underwater sound field radiated by breaking waves. Measurements of the ambient noise in the frequency range 20Hz - 20kHz, generated by laboratory breaking waves, are presented. It has been observed that the sources of sound in spilling breakers are primarily in the frequencies ranging from 300 Hz to 20 kHz. The plunging waves, however contributes to the noise spectrum from less than a few hundred hertz to 20 kHz. Attempts have been made to correlate breaking wave acoustics with the dynamics of breaking waves. The acoustic radiated energy has been found to be proportional to energy dissipation and the square of the maximum wave slope parameter.|
