FIELD: acoustics.
SUBSTANCE: invention relates to industrial acoustics, particularly, to broadband noise suppression, and can be used in all branches of the national economy as a means of protection from noise. Method is that bearing walls are faced with sound-absorbing structures, and also single sound absorbers are installed, in which a sound-absorbing material is disposed, and they are installed over noisy equipment. First, the octave levels of sound pressure are determined taking into account the maximum possible sound absorption. And after the installation of sound-absorbing structures in the shop at the workplace in the zone of direct sound.
EFFECT: technical result is increased efficiency of noise suppression.
