Trees do not only improve air quality by removing carbon dioxide from the atmosphere. They can also significantly reduce noise levels by absorbing and refracting sound waves. Scientists from Brno are currently investigating how trees could be used as sound barriers against traffic noise.

A team of scientists from the Moravian city of Brno are currently carrying out research in Czechia’s forests to find out to what extent trees and other vegetation could help reduce the noise from traffic.

Using the 3D images and the data on transmission of sound, scientists then create models of different types of forests. Based on these models, foresters could select the ideal mix of trees around roads and railways that would not only serve as an effective sound barrier but also withstand warmer and drier climates.
