Laboratory studies of near-grazing impulsive sound propagating over rough water

Qin, Qin; Lukaschuk, Sergei; Attenborough, Keith

Abstract

Acoustic impulses due to an electrical spark source (main acoustic energy near 15 kHz) have been measured after propagating near to the water surface in a shallow container resting on a vibrating platform. Control of the platform vibration enabled control of water wave amplitudes. Analysis of the results reveals systematic variations in the received acoustic waveforms as the mean trough-to-crest water wave amplitude is increased up to 7 mm. The amplitudes of the peaks corresponding to specular reflections are reduced and the variability in the tails of the waveforms is increased. (C) 2008 Acoustical Society of America.
