Investigation on noise absorption by plants

Investigation: Why can plants reduce airport noise

Planting green plants can not only beautify the environment and activate the atmosphere, but also purify the air and remove the harmful substances in the air. At present, according to research, planting green plants can also reduce noise.

The reason why plants reduce noise: sound propagation depends on sound wave expanding outward. When the sound wave touches the tree trunk, it breaks and scatters the sound wave. Moreover, the tree trunk is luxuriant and leafy, and the leaves are arranged in different shapes. It often swings with the wind, producing sound waves opposite to noise, which can offset the transmission energy of sound waves and weaken noise. In addition, the uneven structure of the pores on the surface of the leaves, as well as the tufts of hair, like porous fiberboard, can absorb the noise. In a word, the plants with luxuriant branches and leaves have the function of sound insulation

From the point cloud model, we can see that there are many green plants around the airport and press Rd Brooklyn Park. These green plants can reduce the damage of Adelaide Airport Noise to nearby residents to a certain extent. As the residents living near the airport are inevitably affected by the airport noise, the local government should increase the local greening construction and actively expand the green area, so as to reduce the airport noise to a certain extent and give the residents a quiet living space.
