“Noise pollution is a silent crisis undermining constitutional rights, ecological stability, and public health, but Indian policy response has remained inadequate.” Critically examine. (10M)

Noise pollution refers to unwanted or harmful levels of sound that disrupt normal activities and threaten health and environment. It is an invisible pollutant, often neglected in policy debates compared to air or water pollution. The UNEP Frontier Report 2022 identified five Indian cities among the world’s noisiest (Delhi, Kolkata, Mumbai, etc.). Despite legal recognition, enforcement and policy innovation remain weak.

Constitutional and Legal Dimensions:

• Article 21 (Right to Life and Dignity): The Supreme Court has expanded it to include freedom from hazardous noise.
• Article 48A & 51A(g): State and citizen duty to protect the environment.
• Noise Pollution (Regulation and Control) Rules, 2000: Prescribes limits (e.g., 55 dB in residential daytime, 40 dB in silence zones at night).
• Judicial Pronouncements:
  • In Re: Noise Pollution (2005): Ban on loudspeakers from 10 pm to 6 am.
  • Bombay HC (2016): Loudspeaker use is not a fundamental right.
  • SC (2024): Declared freedom from noise as part of Article 21.

Causes of Rising Noise Pollution:

• Urbanisation & Construction – Metro, highways, real estate drilling.
• Traffic & Transport – India has one of the highest levels of honking; air and railways add further noise.
• Social Practices – Loudspeakers in festivals, elections, and religious gatherings.
• Industrial & Agricultural Machinery – Generators, mills, tractors, harvesters.
• Weak Governance – Poor urban planning, lax monitoring, fragmented responsibilities.

Impacts of Noise Pollution:

Human Health:

• WHO estimates:  Prolonged exposure above 65 dB causes hypertension, cardiovascular issues, sleep disruption, and even premature deaths.
  • On children: impaired concentration, poor learning outcomes.

Mental Well-being: Irritability, reduced productivity, stress.

Ecological Impact:

• Auckland 2025 study: Birds lose communication and mating calls due to combined effects of noise and artificial light.
  • Marine mammals (whales, dolphins) disoriented by shipping noise and sonar.
• Social Justice: Urban poor living near traffic corridors and construction sites bear disproportionate burdens.

Policy Gaps:

• National Ambient Noise Monitoring Network (2011): Limited to 70 stations, largely inaccessible to the public, functioning as a passive record-keeper.
• Institutional Fragmentation: SPCBs, urban local bodies, and police work in silos with little coordination.
• Weak Enforcement: Even “silent zones” (schools, hospitals) often record 65–70 dB, violating standards.
• Low Political Priority: Air pollution dominates discourse, sidelining noise despite comparable health risks.
• Public Attitudes: Honking and loud celebrations are socially normalized.

Way Forward:

1. Decentralised Real-time Monitoring: Expand NANMN; data dashboards for citizens and municipalities.
2. Urban Planning Solutions: Acoustic zoning, noise barriers, green belts, promotion of electric vehicles.
3. Strict Enforcement: Higher penalties for traffic, industrial, and construction violations.
4. Behavioural Interventions: Campaigns like “No Honking Days”, community-led noise audits, school sensitisation.
5. Technological Solutions: Smart traffic management, silent machinery, soundproof public infrastructure.
6. Sonic Empathy & Citizen Participation: Build cultural sensitivity towards silence as a public good.

Conclusion:

To safeguard Article 21’s promise of dignified life, noise must be treated on par with air and water pollution. Moving from symbolic laws to systemic, participatory governance is the only way to restore the right to silence in Indian cities.

‘+1’ Value Addition:

• WHO: Safe noise level is below 55 dB during the day and 40 dB at night. Anything above 70 dB for long-term exposure can cause irreversible hearing loss.
• CPCB (2023 study): Peak noise levels in Delhi traffic corridors reached 85–95 dB, well above limits.
• Church of God v. K.K.R. Majestic (2000): SC ruled that religious freedom cannot override right to health and peace.
• EU Environmental Noise Directive (2002): Mandates noise maps and action plans for cities with more than 100,000 population.
• Germany & Netherlands: “Quiet zones” in cities with strict fines for honking.
