Experimental Study on Acoustics of Different Intensities of Breaking Waves
This paper presents the results obtained from a laboratory investigation on the acoustics of breaking waves of different intensities. Measurement of the wave breaking noise in the range of 20Hz - 20kHz is presented. The experiments were carried out in a 30m long and 2m wide wave flume with 0.8m water depth at Department of Ocean engineering, Indian Institute of Technology Madras. Wave breaking has been generated through wave-wave interaction associated with a frequency and amplitude modulated packet. Plunging and spilling type breakers have been generated. In the case of plunging breaking, the low frequency noise components are dominant. Time-frequency analysis has shown the acoustically dynamic part of the breaking wave event. The measurement of the sound generated by the breaking waves could quantitatively be used to understand the dynamics of the breaking process. The acoustic energy radiated by breaking waves is found to be well correlated with the rate of energy dissipation.
