Vegetation for noise reduction

This concerns the role vegetation can play in some contexts to reduce noise. The measurable effect of vegetation in reducing noise has been debated, yet if the layer is thick and dense, the effect can be substantial1,2. The ground effect related to the soil substrate should be raised in this context3, as well as visual screening (cf. Visual masking) and the sound of rustling leaves (cf. Auditory masking and Effects of vegetation).
