Noise From Vehicles

Vehicles are a common source of noise pollution in India. You can be fined if you misuse your vehicle horn by:

• Sounding the horn in a silent zone
• Sounding the horn needlessly or continuously in a manner which is more than necessary to ensure your or others’ safety
• Sounding the horn during night time (10 p.m. to 6 a.m.) in residential areas except during a public emergency.
• Sounding a multi-toned horn that gives an unduly harsh, shrill, loud or alarming noise.

Even at the manufacturing stage of cars there are noise limits which have to be followed otherwise you will be punished with jail time and fine 

Silencers

Every motor vehicle including agricultural tractors have to be fitted with a silencer which by means of an expansion chamber or otherwise so that it reduces as far as practicable possible, the noise made by the escape of exhaust gages from the engine.

• Civil airports which have less than 15000 aircraft movement annually
• Defense aircraft, aircraft landing and take off noise, aircraft engines, helipad locations.

If airports do not follow the noise standards given below then the authorities will take action against the airport.
