Noise pollution, legally an air pollutant under the Air (Prevention and Control of Pollution) Act, 1981, causes hypertension, sleep disruption, stress, and cognitive decline, yet India lacks systematic monitoring and comprehensive data.

Noise Standards vs. Ground Reality

• WHO Standard: The World Health Organization (WHO) recommends daytime residential noise levels should not exceed 55 dB(A), equivalent to a normal conversation.
• Indian Legal Norms: The Noise Pollution (Regulation and Control) Rules, 2000 set similar limits — 55 dB during the day (6 am to 10 pm) and 45 dB at night.
• Ground Reality: Traffic corridors in Indian cities often exceed 70 dB(A), which is dangerously higher than prescribed norms and contributes to serious health risks.

Burden of Noise Pollution

• Vulnerable Groups at Risk: The burden of noise pollution is heaviest on street vendors, delivery workers, traffic police, and residents of informal settlements, for whom it is a daily occupational hazard rather than a rare nuisance.
• Lack of Protective Capacity: Those most exposed to noise pollution have the least resources or capacity to protect themselves, making them disproportionately vulnerable.
• Inequality in Protection: Quiet homes and soundproof workplaces remain luxuries for the wealthy, while poorer sections bear the brunt of exposure without safeguards.
• Right to Quiet as Public Health: The right to quiet must be recognized as a baseline condition of public health, not a privilege for elites, ensuring equitable well-being for all citizens.

Challenges in Addressing Noise Pollution

• Inadequate Monitoring: Noise monitoring in India is sporadic, reactive, and incomplete. 
  • Unlike air pollution, where satellites and low-cost sensors have transformed measurement, policymakers lack reliable and continuous noise data.
• Weak Enforcement and Cultural Barriers: Enforcement mechanisms remain weak, and citizens often do not perceive noise as harmful as smog. 
  • Social and cultural practices such as excessive honking, festival celebrations, and unregulated construction activities reinforce tolerance of high noise levels.
• Fragmented Governance: Responsibility for noise regulation is scattered across pollution control boards, municipalities, and the police. 
  • Each authority has limited resources and weak incentives, which prevents coordinated and effective action.

Way Forward

• Treat Noise Pollution on Par with Air and Water Pollution: Noise must be integrated into clean-air agendas, and interventions must be evidence-based and rooted in public health data.
• Strengthen Monitoring Mechanisms: Real-time noise sensors should be deployed across cities to generate integrated noise maps. 
  • Machine learning tools should be used to identify noise sources such as traffic, construction, and industry. 
  • Health studies must track noise exposure near sensitive sites such as schools, hospitals, and low-income neighborhoods.
• Integrate Noise Mitigation into Urban Planning: Urban planning should incorporate green buffers like parks and tree belts, which can absorb sound. 
  • Zoning regulations must shield residential areas from high-intensity noise corridors.
  • Experiments with noise-reducing green belts should be scaled up through scientific assessment and community participation.
• Reform Governance Structures: Noise regulations should be enforceable, backed by transparent data and accountability. 
  • Agencies such as pollution boards, transport departments, and municipalities must collaborate to reduce noise. 
• Promoting walking, cycling, faster adoption of electric buses, and stricter enforcement of honking restrictions can provide measurable relief.
• Ensure Community Engagement: Since noise is tied to social and cultural practices, solutions must be both sensitive and firm. 
  • Public awareness campaigns and partnerships with religious and community leaders can help reshape norms without alienating communities.

Conclusion

• Recognising the right to quiet as part of the right to life under Article 21, India must integrate noise control into urban health agendas. Effective regulation will advance SDG 11 (Sustainable Cities and Communities) and safeguard vulnerable groups, promoting a more equitable and livable urban future.
