The Effect of Temperature on Low-Frequency Sound Attenuation in Fresh and Salt Water.
Abstract
The anomalous attenuation observed both in fresh and sea water at 4C can be described by a relaxation-type expression, with the relaxation frequency equal to 1 kHz. From the limited data available at a different temperature, the activation energy was computed and is of the same magnitude as hydrogen bonding. Further experiments are planned for Lake Tanganyika and the Red Sea to establish the thermal behavior of the 1 kHz absorption.
