High-frequency ambient-noise measurements were made in five North American ports. At a given frequency, the total span of noise levels for the five harbors was about 25 dB. At 30 kHz, levels 30 dB higher than the extrapolated deep-water Knudsen value for sea state 2 were observed. Comparison is made with some 20- to 50-kHz data for other harbors.
