- Most of the sound pressure, which is produced by the engine is emanating out of the vehicle by using the piping absorb by a series of passages and the chambers
- the technique to control noise is known as muffler in an engine and to control noise pollution with the help of planting trees is Green Muffler.
- According to USDA National Agro forestry Center a properly designed buffer of trees and shrubs can reduce noise by about 10 decibels or about 50% as perceived by the human ear.
- Green Muffler is a technique of reducing noise pollution by planting 4-6 rows around the populated areas or noisy places like along roadsides, industrial areas, societies near highways, etc. so that dense trees reduce noise pollution as they filter out the noise and obstruct it reaching the citizens
- They control noise pollution. Even urban noises are muffled by trees just like stone walls.
- – An advantage of using plants as noise blockers is that they absorb sounds best in the high frequencies that people find it annoying.
- – Evergreen shrubs that too with broader leaves provide year round noise protection so, they are best to plant. Trees absorb sound waves with their branches and foliage.
- – Plant trees with no space or less space to reduce noise pollution.
- – In fact soft ground is an efficient noise absorber. So, avoid hard surfaces to plant trees..
