Trees as a Barrier to Unwanted Sound

A lot of people are finding an answer to the question since long, ‘how noise can be reduced’? And the simple answer to this question is that noise is reduced either by the deflection or absorption of noise or a combination of two. But, it is practically not that easy. The noise barriers have to be placed as close as possible to the source of the noise. While on the other hand, most of the hardscape barriers work solely by deflecting sound. 

Environmental Eco Barriers

The earthen berms are majorly used in the combination with the trees and shrubs with an aim to deflect and absorb sound when space is limited. While on the other hand, large-leaved deciduous species are more effective when it comes at reducing noise and above all the methods; evergreens are the best environmental barriers providing the best results of soundreduction year around.

A lot of factors are there that are to be considered before deciding to create a tree barrier against noise. Keep all these factors in mind before you proceed with the creation of such a noise barrier:

  • Noise is more effectively reduced by completely screening the source from the view.
  • The barriers are to be planted as close to the noise source as possible.
  • Use wide belts of high-density trees and shrubs to achieve significant results of noise reduction.
  • The effectiveness of sound reduction depends on the density of stems, branches and leaves.
The environmental noise barriers have always been a great source of noise reduction as they do not restrict the sound waves rather they absorb the maximum amount of noise and do not allow them to enter. For year-round noise reduction, it is great to use broadleaved evergreens or a combination of coniferous and evergreen species.
