Noise control to solve the problem of neighbor’s complaints to our company

Compliance with the noise emission standards set by the Superintendencia del Medio Ambiente (SMA) is clear for companies that generate environmental noise. By law, this gives the affected neighbors the right to complain about the situation. If your company suffers from these complaints, we can tell you how to proceed with noise control.

Environmental acoustics problems in your business

Complaints from neighbors about problems related to noise control may be rooted in a lack of knowledge of the regulations or failures in the acoustic engineering of their facilities. In order to verify your situation, you require a detailed diagnosis that will allow you to resolve the situation and comply with the established statute.

As a basic guide to the limits established for environmental acoustics, there is a table indicating the values, which can be summarized as follows:

  • Zone 1. Located within the urban boundaries and for residential use. Decibels from 7 a.m. to 9 p.m. should be 55 and between 9 p.m. and 7 a.m. should be 45.
  • Zone 2. Also within the confines of the city, with public space and permission for equipment. The dB should not exceed 60 (7 to 21) or 45 (21 to 7).
  • Zone 3. Located on the edge of the urban area, with green spaces, license for equipment at any scale and infrastructure or productive activities. From 7 to 21, the tolerable decibels are 65 and from 21 to 7 they are reduced to 50.
  • Zone 4. Within the urban perimeter and exclusively for productive or infrastructure activities. During daytime (7 a.m. to 9 p.m.) and nighttime (9 p.m. to 7 a.m.) the dB should not exceed 70.
