What is an environmental noise report?

Is a technical document that certifies noise measurements results, evaluating the conditions of acceptability of the noise on communities, regardless the existence of complaints and confronting with legal parameters according to the NBR ABNT 10.151:200, which concerns about noise limits.

What is the content of an environmental noise report?

The NBR ABNT 10.151:200 defines the measurement procedures, which must be performed outside the building containing the noise source.

The report must specify the procedures used, the days and time, the sources of noise and the measurements results, with a comparison between the noise level identified and the NCA assessment level (level of assessment criteria) to external environments, as well as specify the characteristics of the noise and the meter calibration date.
