The important influence of breaking waves on the dynamics of the upper ocean has motivated research into developing techniques for quantitatively measuring the effects of wave breaking in the field. Breaking waves are a major source of sea surface sound and breaking events produce sound at frequencies as low as 10 Hz. Collective bubble cloud oscillations have been shown to be the dominant source of the low‐frequency sound. Laboratory experiments have shown that the low‐frequency sound generated by breaking is correlated with the amount of wave energy dissipated and the volume of air entrained. Therefore it may be possible to use passive acoustic measurements in the field to obtain estimates of the volume of entrained air and energy dissipated by individual breaking events. Development of a model of the low‐frequency sound generated by individual breaking waves is an important step in achieving this goal. A simplified model of the low‐frequency sound generated by breaking has been developed based on the approach of Oguz [J. Acoust. Soc. Am. 95(4), 1895–1912 (1994)]. The importance of the simplifying assumptions used in the model and the use of the model as an aid to interpreting field and laboratory measurements will be discussed.
