An obstacle, such as a wall, that blocks the line-of-sight between a sound source and a receiver, thereby providing a barrier attenuation, i.e., a reduction of sound level at the receptor. Sound attenuation provided by barriers is principally related to the diffraction of sound over and around the barrier, and the sound transmission loss through the barrier material.
