The study assessed 76 samples from 13 tree species that displayed a variety of different bark characteristics.Sound 'silencer'Co-author Jian Kang, from University College London (UCL), said: "Beside emphasising the effects of vision and shade, urban greening should be considered as well to achieve noise reduction during prop…
