Is landscaping an effective noise barrier?
The use of landscaping (trees and shrubs) as a noise screen is only effective if there is at least 75-100 feet of dense, evergreen vegetation between the noise source and the listener. There is usually not enough right-of-way between a roadway and nearby residences to provide an effective vegetative noise screen. Some people may perceive that landscaping or decorative fencing decreases noise level because it is “out of sight, out of mind”.
