when the surface is parallel, the sound is not refracted by the surface. for eg; when a light ray is focussed on a parallel plate they reflect and not refract. more over the surface is parallel there may not be any diffusion. as per acoustics only cardboards and some other materials absord sound and since it is parallel i think it does not absorb the sound. then it is ounly by focussing
