Estimates of sound (and infrasound) spectral levels are given using a theoretical model of acoustic production based on quadratic interactions of oppositely traveling ocean waves, and incorporating present day surface wave spectral models. It is shown that reasonable agreement with measurements exists for frequenices less than 10 Hz but predictions are 10–15 dB low and have the wrong spectral shape at higher frequencies.Subject Classification: [43]30.40; [43]20.15; [43]30.70; [43]28.65.
