- Title
Losses during sound propagation on the shelf.
- Authors
Rutenko, A.
- Abstract
The paper discusses the results of studying how changes in the hydrological conditions affect losses that sound undergoes as it propagates along a stationary track in Vityaz Bay in the Sea of Japan. Measurements were conducted with an Mollusk-07 autonomous vertical acousto-hydrophysical measurement system and an autonomous electromagnetic emitter generating a frequency-modulated signal in the 280-340 Hz band. The modulation frequency was 0.3 Hz. It is shown that tide-, internal-wave-, and upwelling-caused variations in sound losses with a frequency of 285-335 Hz propagating along a stationary track with a length of 1640 m for seven days did not exceed 3 dB.
