FIELD: physics, acoustics.
SUBSTANCE: method for separation of acoustic signal on noise background is based on simultaneous reception of noise along two different channels and reception of pressure along one of these channels. Vertical component of pressure receiver displacement is received through the second channel, and electric signals at the outlet of these channels are subtracted.
EFFECT: compensation of noise caused by vertical displacement of sound pressure receiver at low sound and infrasound frequencies.
