Noise pollution is increasingly recognized as a significant environmental issue, second only to air pollution in terms of health impacts, according to the European Environmental Agency. Some of its effects are listed below.
Human Health:
- Physical/Psychological: Long-term exposure to noise levels above 55-65 dBA can cause hypertension, hearing damage, and sleep disruption.
- Attention: Noise above 85 dBA subtly affects attention, while levels above 95 dBA significantly reduce mental workload and attention.
Economic Impact:
The US Veterans Administration spends over $5 billion annually on hearing disability claims, primarily due to jet propulsion and explosions.
Environmental Impact:
Wildlife: Ocean noise from ships disrupts feeding, breeding, and communication in marine animals, causing them to move from their habitats. Recent research shows similar effects on wildlife near server farms.
Regulations/Development Programs:
- Europe: The Environmental Noise Directive aims to reduce noise by 30% by 2030 compared to 2017 levels.
- US: The Quiet Communities Act of 2021 reestablished the Office of Noise Abatement and Control to support local noise control programs, with a budget of $21 million per year from 2022 to 2026.
- FAA CLEEN Program: Phase III of the FAA's CLEEN (Continuous Lower Energy, Emissions, and Noise) Program targets a 25 dB cumulative noise reduction relative to Stage 5 requirements and/or reduces community noise exposure.
