Scientists say trees have a role to play in combating noise pollution in urban environments and
have identified the best species for the job.
The larch was found to be the most effective tree when it comes to absorbing noise with its bark.
The conifer was the most effective out of 13 tree species in a laboratory-based sound absorption test.
The researchers say the findings can help urban planners use trees for noise control.
The results have been published in the Applied Acoustics journal.
The study assessed 76 samples from 13 tree species that displayed a variety of different bark characteristics.
