What are India's ambient noise standards?

CPCB prescribes ambient noise standards under the Environment Protection Act 1986: Industrial (75/70 dB day/night), Commercial (65/55), Residential (55/45), and Silence Zones (50/40). Noise monitoring follows IS 10399.

When is noise assessment required in India?

Noise assessment is required for EIA clearance, factory consent-to-operate, construction projects near residential areas, and new industrial installations. CPCB and SPCB may mandate noise monitoring as consent conditions.

Does NoiseMap generate SPCB compliance reports?

Yes. NoiseMap generates noise assessment reports with source identification, receptor mapping, predicted noise levels, and compliance checking against CPCB ambient noise standards for all four zone categories.

Noise Impact Assessment Under Indian Regulations

CPCB ambient noise standards under EPA 1986 and Noise Pollution Rules 2000: Industrial 75/70 dB (day/night), Commercial 65/55 dB, Residential 55/45 dB, Silence Zones 50/40 dB. Assessment mandatory for EIA clearance, factory consent, and construction near residential areas.

NoiseMap Methodology

Follows IS 10399 measurement protocols and CPCB guidelines. Identifies sources, maps receptors, predicts cumulative levels, and generates SPCB consent-ready compliance reports with noise contour maps and mitigation recommendations.
