Sea Noise Vs Near and Distant Wave Height and Wind Speed

摘要

Correlation of measurements made in deep, open-ocean areas of the Northeast Pacific indicates: (1) Sound pressure spectrum level is influenced by wave height and wind speed at both ends of the frequency range considered (10 to 400 c/s); influence is greatest between 160 and 400 c/s. (2) Ambient-noise levels between 32 and 160 c/s are the least influenced by near and distant wave height. (3) For periods during which local wave heights were moderate and uniform, no dependence of ambient-noise level on distant wave-height fluctuation was observed. (Author)
