Investigation: Why can plants reduce airport 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
