Noise Monitoring/Noise Risk Assessment (NRA)

Subsequently, zoning will be done to identity the specific noise sources within the area. The layout of the area with machinery location is drawn. Then, the noise contours of below 85 dB (A), 85 to 90 dB (A) and above 90dB (A) are sketched on the plan and are colored for easy identifications. This is conducted by walking with the meter to the mark the distance from the noise sources for each noise contour being measured. All the points for each contour are jointed to complete the zone.

Noise Risk Assessment (NRA) is a new term for noise monitoring .
