Trees are great natural blockers of noise and are able to reduce or attenuate sounds by intercepting sound waves and changing their behaviour. They are able to do this as different parts of their make- up is able to reduce noise by absorbing, deflecting, masking or refracting sound waves.
The parts of a tree that are really good at absorbing sound waves are the branches, stems, leaves and wood. Trees that have large fleshy leaves and rough, thick bark are particularly effective and this is because of their dynamic surface area. The canopy of a tree (also known as the crown) is the area of leave and branches that cover the ground. This covering can help the soil retain moisture which in turn can help reduce noise.
Trees are able to absorb more high-frequency noise than low frequency, which means that they make ideal sound barriers for areas heavily populated. And it’s not just trees that have this absorbing power. Other vegetation like shrubs and large plants can also deflect and reflect sound waves. It’s important to note, however, that sounds cannot be completely blocked by trees; they can only lessen the amount of noise that reaches a certain area.
In addition to being wonderful noise blockers, trees provide other benefits to people and the environment. Some other benefits of trees include being able to:
