Data on underwater surf-generated noise measured near stony, rocky, and sandy coasts of the Black Sea and the Pacific Ocean are presented for a frequency band of 0.03 16 kHz and distances of 0.01 30 km from the coastline. The frequency-power spectra and the excess coefficients in the distributions of the instantaneous values of sound pressure in surf-generated noise are considered for coasts of different types. At surface wave heights of 0.5 0.8 m, the surf-generated acoustic noise near pebble-type coasts is higher than the noise of the open sea at a distance of 10 km from the coast, while the excess coefficients are positive at distances of up to 2.7 km from the coast.
