Masking of the highway
Simplified simulation of how a roadside area can be experienced, depending on the design of the noise barrier and the vegetation. Exactly the same traffic noise has been used in two different scenarios. Especially aspen and other poplars in windy conditions give a strong masking effect. Visual aspects are also important. A noise barrier that is a completely straight raises associations to the road and the large and fast scale available there. An organic and human scale in the shape gives a naturalness that makes it easier to accept the masking.
