High noise screens

High noise screens are approximately 1.8 m and above. These screens should be located as close to the source (or listener) as possible for optimal effect1. The effect depends on a number of factors, where height is the main determinant2. In addition to conventional usage, high noise screens can be used in a creative manner, as part of urban design solutions incorporating features like seating3,4, water and/or vegetation4,5.
