The paper shows the importance of the problem of combating noise pollution in the workplace master production of metal. The calculations of the sound level generated by two non-directional point sources, the result is compared with the current sanitary standards and defined the required level of noise reduction required. The most common method used to reduce the noise in the room. A reliable and efficient method is sound booths. The stages of design choice, the calculation of the parameters of acoustic cabin, made outline drawing proposed acoustic cabin. Produced selection of materials for sound insulation cabins that meet modern requirements. The problems for the creation of a favorable acoustic environment in the workplace. The conclusions of the work done.
