Noise at higher Magnitudes is the cause of multiple Human Health Hazards. Noise Monitoring is the Measurement or Assessment of the Magnitude of Noise within a Specific Area. Industrial Noise Monitoring is a periodical Analysis of Sound Levels in Industrial Areas. Machines are the source of high Noise levels or Sound Pollution and are Damage Causative. Noise Monitoring helps Regulated Industries Monitor and maintain Noise levels within permitted Stipulated Limits.
Decibel (dB) is basically the unit of Noise Measurement within any particular area and “A” in dB (A) Leq stands for Frequency weighting of Noise. In case of Industrial area, the permissible Limit of Noise is 75 dB during the daytime and 70 dB in the night. The Industries had to follow the Noise Monitoring Standards of ISO 3740:2019(en) in maintaining the Noise Control throughout the workforce.
EFRAC offers Industrial Noise Monitoring Services to its Clients in compliance with ISO 17025:2005 Standards.
