Abstract
The contribution of noise created by bubbles at the instant of their formation is considered as a major contribution to sea noise over 1 – 60 kHz. Estimates of the noise from this mechanism have been made by combining laboratory measurements of the average noise made per bubble with the estimated rate of creation of bubbles at sea, both in relation to bubble size. Appeal is made to dimensional similarity arguments for the bubble output, confirmed by experiment, and for the rate of creation of bubbles, consistent with experiment. Frequency dependence predicted, at f-1.5, is close to that observed. The estimated absolute level and windspeed dependence tend to exceed those observed; it is argued that this may indicate a modification in the bubble output, through a local modification in the medium in the vicinity of the breaking wave. Experimental evidence on the spatial concentration of sea noise is shown.
