Abstract
The acoustic signatures of imploding light bulbs have been suggested as an alternative sound source due to their strong broadband energy below 1 kHz and short pulse length. Recently, several studies have presented measurements of the geoacoustic properties and long-range sound propagation in shallow water using light bulbs. The implosion of the bulb generates bubbles in the water the expansion and contraction of the bubbles create subsequent bubble pulses. Measurements of the acoustic properties of underwater implosions have been conducted in recent experiments with incandescent bulbs at variable depths. In this study, 105 shots were deployed in a shallow depth (< 100 m) to determine the depth-dependent characteristics of bulb implosions in water, including the peak source level and primary resonant frequency with depth.coustic properties and long-range sound propagation in shallow water using light bulbs.
