Communication presented at the 17th International Congress on Acoustics, Rome, 2-7 September 2001.
Some basic properties of the impulse response (IR) of noise barriers are presented regarding the derivation of a global rating related to transmission loss of such devices. The possibility of representing every barrier by a unique IR is envisaged and some theoretical results derived from theories of Maekawa and Pierce are compared with experimental results in scale models.
