“…Shonting et a1 [13] made an observation at sea, where they found that the level at 15 kHz was a good indicator of the presence of rain, but they had difficulty in explaining, why the sound level associated with the lowest rain rate was higher than the sound level associated with the highest rain rate.…”

An overview over the most important results obtained over the past of noise produced in water by impacts of single droplets, artificial rain and real rain is presented. Two distinct sources form the major contributors to rainfall produced noise in the sea. The raindrop impact and the pulsations of entrained air bubbles. The impact sound is produced by raindrops of all sizes, while the bubble pulsations are connected with regular entrainment of small gas bubbles, leading to the characteristic peak spectral level between 14 and 16 kHz, and by irregular entrainment of larger gas bubbles produced by impact of large raindrops. The noise spectra are discussed and interpretations of their relations to the raindrop size and impact mechanisms are given. Relations between noise spectra and rainfall rates are discussed and some still unsolved problems are pointed out, particularly related to estimation of light and moderate rainfalls using underwater sound measurements.

“…In majority of the literature, the wind-generated noise is classified to be due to two processes [6][7][8][9]. One is due to the wave breaking events, which occurs at higher wind speeds and the other due to collective oscillation of bubbles at their resonant frequency.…”
