Sound Transmission through Vegetation in Relation to Leaf Area Density, Leaf Width, and Breadth of Canopy

Transmission of random noise through dense reeds (Phragmites communis) was measured. The ground surface was water and thus ground attenuation could be closely determined. A single relationship between leaf area density, breadth of canopy, leaf width, and frequency is presented, which allows the attenuation due to a stand of herbaceous plants to be estimated.
