The 'Green Muffler' technique involves planting trees and shrubs along roads, industrial areas, and noisy zones to mitigate noise pollution. The vegetation acts as a natural barrier, absorbing and reducing sound levels effectively.
Information Booster
1. Commonly planted species include Neem, Ashoka, and Bamboo, known for their dense foliage.
2. The Green Muffler is especially effective near highways, railway tracks, and airports.
3. Trees absorb sound waves through their leaves, branches, and stems.
4. This method also improves air quality by absorbing pollutants.
5. Dense vegetation can reduce noise levels by 10–15 decibels.
6. Green belts are an integral part of urban planning and pollution control.
7. Noise pollution can cause health issues like hearing loss, stress, and heart problems.
