Noise limits in India: what the Rules allow, and how to complain

Last updated: September 20, 2026

The limits by zone

The Schedule to the Rules sets one national table, "Ambient Air Quality Standards in Respect of Noise", in dB(A) Leq. State Governments categorise areas into the four zones; a mixed area may be declared as any one of them by the competent authority.

The Schedule's own notes define the two periods: "Day time shall mean from 6.00 a.m. to 10.00 p.m." and "Night time shall mean from 10.00 p.m. to 6.00 a.m." The unit is explained in the same place: "dB(A) Leq denotes the time weighted average of the level of sound in decibels on scale A which is relatable to human hearing." A single loud moment is not a breach; a source that keeps the average above the line is.

Silence zones

Rule 3(5): "An area comprising not less than 100 metres around hospitals, educational institutions and courts may be declared by the State Government as silence area/zone for the purpose of these rules." The proviso added in 2000 makes the notification the test: "an area shall not fall under silence area or zone category, unless notified by the State Government". Inside a notified silence zone, Rule 6 makes it an offence to play music or use amplifiers, beat a drum or blow a horn, exhibit performances that attract crowds, burst sound-emitting firecrackers or use a loudspeaker, "liable for penalty under the provisions of the Act".

What is restricted at night

Rule 5(1): "A loud speaker or a public address system shall not be used except after obtaining written permission from the authority." Rule 5(2), as amended in 2010, bars a loudspeaker, public address system, "any sound producing instrument or a musical instrument or a sound amplifier" at night time "except in closed premises for communication within, like auditoria, conference rooms, community halls, banquet halls or during a public emergency". Rule 5(3) lets a State Government permit loudspeakers "during night hours (between 10.00 p.m. to 12.00 midnight) on or during any cultural, religious or festive occasion of a limited duration not exceeding fifteen days in all during a calendar year", with the days specified in advance.

Rule 5A, added in 2010, adds three plain rules: "No horn shall be used in silence zones or during night time in residential areas except during a public emergency", "Sound emitting fire crackers shall not be burst in silence zone or during night time", and "Sound emitting construction equipments shall not be used or operated during night time in residential areas and silence zones".

How to complain

Rule 7(1): "A person may, if the noise level exceeds the ambient noise standards by 10 dB(A) or more given in the corresponding columns against any area/zone or, if there is a violation of any provision of these rules regarding restrictions imposed during night time, make a complaint to the authority." Rule 7(2): "The authority shall act on the complaint and take action against the violator in accordance with the provisions of these rules and any other law in force."

The "authority" is defined in Rule 2(c) as any officer authorised by the Central or State Government "and includes a District Magistrate, Police Commissioner, or any other officer not below the rank of the Deputy Superintendent of Police designated for the maintenance of the ambient air quality standards in respect of noise". In practice that is the local police station or police control room, the district administration, or the State Pollution Control Board or Pollution Control Committee, which under Rule 4(3) also publishes the noise data for its state. The CPCB keeps the list of designated authorities by state on the same page as the Rules. Under Rule 8 the authority can order music or noise stopped once satisfied, from a police report or the complainant, that it causes "annoyance, disturbance, discomfort or injury".

Rule 7 sets the threshold at 10 dB(A) above the zone limit, so a residential-area complaint about the night needs a level of 55 dB(A) or more, measured as an average, not a peak. Take a reading with the free online decibel meter with A-weighting on, over a full minute, and note the time; it runs in your browser and records nothing. It is an uncalibrated estimate of about ±10 dB, enough to tell 50 from 70 but not evidence on its own; the authority measures with a calibrated instrument. The noise complaints guide covers what to log before you call.

Rules in the big cities

The limits above are the same everywhere; who enforces them, how to complain and which local orders apply differ by state and city. Each city page is read from that state's and city's own official documents:

• Noise rules in Delhi (National Capital Territory of Delhi)
• Noise rules in Mumbai (Maharashtra)
• Noise rules in Bengaluru (Karnataka)
• Noise rules in Kolkata (West Bengal)
• Noise rules in Chennai (Tamil Nadu)
• Noise rules in Hyderabad (Telangana)
• Noise rules in Pune (Maharashtra)

What the Rules do not do

They set no fixed fine of their own; violations are punishable "under the provisions of the Act", the Environment (Protection) Act, 1986, which the Rules are made under. They do not regulate vehicle exhaust or horn design, which sit in the motor vehicle rules, and they leave the categorisation of every locality to the State Governments, so a street's zone is a matter of the state's notification, not of how it looks. Court orders, notably the Supreme Court's 2005 judgment on noise pollution, have added directions on top of the Rules; the text quoted here is the Rules themselves.

What is the permissible noise limit in a residential area in India?

55 dB(A) Leq during the day (6 a.m. to 10 p.m.) and 45 dB(A) Leq at night (10 p.m. to 6 a.m.), under the Schedule to the Noise Pollution (Regulation and Control) Rules, 2000. Commercial areas are allowed 65 by day and 55 at night, industrial areas 75 and 70, and silence zones 50 and 40.

What are the night hours under the noise rules?

The Rules define night time as the period between 10.00 p.m. and 6.00 a.m., and day time as 6.00 a.m. to 10.00 p.m. The lower night limit applies in every zone, and loudspeakers, horns in residential areas, firecrackers and sound-emitting construction equipment are restricted at night.

Are loudspeakers allowed at night in India?

Not in the open. Rule 5 bars loudspeakers, public address systems, sound-producing and musical instruments and amplifiers at night except in closed premises such as auditoria, community halls and banquet halls, or in a public emergency. A State Government may allow use up to midnight for cultural, religious or festive occasions on at most fifteen days in a calendar year, specified in advance.

How do I file a noise complaint in India?

Rule 7 lets any person complain to the designated authority when noise exceeds the zone standard by 10 dB(A) or more, or when a night-time restriction is broken. The authority is a District Magistrate, Police Commissioner or an officer of at least Deputy Superintendent of Police rank designated for the purpose; in practice that means the local police, the district administration or the State Pollution Control Board, which the CPCB lists by state.

Is 55 dB loud?

About the level of a quiet office or a conversation heard from the next room. It is an averaged level (Leq) over the measurement period, not a peak, which is why a single loud event does not by itself breach the standard while a persistent source does.
