When organizing a site for the processing of used tires at a motor transport enterprise, a wide range of harmful and hazardous production factors leads to increased noise levels. The source of his education is a disintegrator. It was established that at the studied workplace the equivalent sound level is 88 dBA with a norm of not more than 80 dBA (for the 2nd class). Not only the operator, but also workers performing their labor functions nearby are ex-posed to noise in the study area. The solution to the problem of reducing noise exposure is associated with a preliminary calculation of acoustic screens, determining the necessary area of sound-absorbing material, fasteners, etc. The performed studies show the need to install 7 screens with a total area of 20 m2 to satisfactorily reduce the sound level to the values regulated by sanitary and hygienic requirements. A decrease in the prevailing factor will entail a general decrease in the class of working conditions by hazard and hazard of the operator by one degree.
