noise pollution for 30 September 2025

Noise pollution has emerged as a growing environmental concern in India as well as globally. It refers to the excessive and unwanted sound that disrupts normal life and causes harmful effects on human health, environment, and economy. According to the Noise Pollution (Regulation and Control) Rules, 2000, noise above 55 decibels (dB) during the day and 45 dB at night is harmful to human health. In India, with rapid urbanization, industrial growth, and increasing traffic, noise pollution has become one of the most pressing urban environmental issues.

Noise Pollution in India

India is among the world’s most affected countries in terms of urban noise levels. The Central Pollution Control Board (CPCB), under the Noise Pollution (Regulation and Control) Rules, 2000, sets permissible noise limits for different zones such as industrial, commercial, residential, and silence zones. However, major Indian cities like Delhi, Mumbai, Kolkata, and Bengaluru regularly exceed these limits. For example, the CPCB 2023 survey recorded average noise levels in Delhi ranging from 65-75 dB during the day, well above the permissible limit of 55 dB for residential areas.

Noise Pollution Sources

Noise pollution arises from a wide range of human and industrial activities. The major causes include:

• Vehicular Traffic: Heavy use of cars, motorcycles, buses, and trucks. In cities like Delhi and Mumbai, traffic noise is the largest contributor.
• Industrial Activities: Factories, construction sites, and power plants generate continuous high-decibel noise.
• Urbanization and Construction: Roadwork, metro rail construction, flyovers, and housing projects significantly add to city noise.
• Social and Cultural Activities: Use of loudspeakers in marriages, religious events, festivals, and political rallies.
• Air Traffic: Airports near cities increase noise exposure for nearby residents. For example, areas around IGI Airport, Delhi experience noise levels above 70 dB.

Noise Pollution Impact

The Noise Pollution impacts the Human Beings as well as the wildlife and environment adversely. Below we have discussed the impact of noise pollution:

1. Impact of Noise Pollution on Health

Excessive noise exposure has serious health effects. WHO identifies noise pollution as the second biggest environmental cause of health problems after air pollution in Europe. In India, similar concerns are rising.

• Hearing Loss: Long exposure above 85 dB can lead to permanent hearing damage.
• Sleep Disturbances: Night-time noise disrupts rest and reduces productivity.
• Cardiovascular Diseases: High noise levels increase risk of hypertension, stress, and heart attacks.
• Mental Health Issues: Anxiety, irritability, depression, and reduced concentration.
• Child Development Issues: Studies show children exposed to noise near airports have lower reading comprehension and memory.

2. Environmental and Social Impact of Noise Pollution

Noise pollution not only affects humans but also impacts the environment and animals.

• Wildlife Disturbance: Animals in forests and urban areas face stress and habitat disturbance. Bird communication gets disrupted, affecting breeding.
• Marine Noise Pollution: Increasing ship traffic and industrial activity harm whales and dolphins that rely on sound for communication.
• Social Impact: Reduced quality of life in urban areas, increased complaints in residential colonies, and decline in property values in high-noise areas.

Permissible Noise Levels in India (CPCB)

According to the data released by CPCB, The Noise Pollution (Regulation and Control) Rules, 2000, the permissible limit for the Noise Levels based on the zones and areas is tabulated below:

Permissible Noise Levels in India (CPCB)
Zone/ Area	Daytime Limit (6 am-10 pm)	Night-time Limit (10 pm-6 am)
Industrial	75 dB	70 dB
Commercial	65 dB	55 dB
Residential	55 dB	45 dB
Silence Zone	50 dB	40 dB

Global Scenario of Noise Pollution

Noise is a worldwide challenge. According to WHO’s 2018 report, around 1.6 million healthy life years are lost annually in Western Europe due to environmental noise. The European Environment Agency (EEA) noted that more than 100 million people in Europe are exposed to harmful noise levels above 55 dB. In the United States, the EPA estimates that nearly 30 million workers are exposed to hazardous noise levels at workplaces.

Noise Pollution in Indian Cities

As per the latest data released by the CPCB Annual Report 2017 under “Status of Ambient Noise Level in India 2017”, the approximate level of Noise in major cities of the Indian States are listed below:

Noise Pollution in Indian Cities
City	Average Day Noise (dB)	Permissible Limit (dB)	Status
Delhi	70-75	55	Above Limit
Mumbai	68-72	55	Above Limit
Kolkata	65-70	55	Above Limit
Bengaluru	66-71	55	Above Limit
Lucknow	64-70	55	Above Limit

Noise Pollution Legal Framework and Regulations

The Indian government and the Supreme Court of India has taken several steps to address noise pollution:

• Noise Pollution (Regulation and Control) Rules, 2000 under the Environment Protection Act, 1986.
• Motor Vehicles Act, 1988 to regulate use of horns and silencers.
• Factories Act, 1948 for worker safety against occupational noise.
• Role of National Green Tribunal (NGT) in hearing cases and imposing penalties on violators.
• Supreme Court Judgments restricting use of loudspeakers and firecrackers beyond permissible limits.
• Noise Monitoring Network: CPCB launched a National Ambient Noise Monitoring Network (NANMN) in 2011 covering 35 cities.
• Silence Zone Enforcement: Strict regulations around hospitals, schools, and courts.
• Smart City Mission: Integration of noise mapping for sustainable urban planning.
• Public Awareness Campaigns: Use of “No Horn” campaigns in metro cities.

Preventive Measures for Noise Pollution

Solutions require both policy action and public participation.

• Promotion of electric vehicles and improved public transport.
• Use of sound barriers and green belts along highways.
• Strict enforcement of permissible decibel limits in residential areas.
• Adoption of silent generators and machines in industries.
• Awareness campaigns to reduce honking and loudspeaker usage.
• Urban planning to create noise buffer zones.

Challenges in Controlling Noise Pollution

Despite existing regulations, several challenges hinder effective control of noise pollution:

• Non-Compliance: Many individuals and organizations flout noise norms, especially during festivals and public events.
• Lack of Awareness: Public awareness about the health impacts of noise pollution is limited.
• Inadequate Enforcement: Enforcement agencies often lack the resources and manpower to monitor and control noise pollution effectively.
