High-frequency acoustic noise of Lake Baikal
Abstract
High-frequency noise of Lake Baikal is investigated using a submersible self-contained instrument to determine the noise background for the acoustic detection of superhigh-energy neutrinos. It is found that, under stationary and uniform meteorological conditions, the integral noise power in the frequency band 1-50 kHz is virtually independent of depth and is 10-200 mPa or more, depending on the specific conditions. The noise itself contains multiple short pulses of different amplitudes and shapes.
