flat areas reflect more sound and produce echos and reverberation, whereas irregular shaped areas
produce less.

b. Absorption. When sound strikes a surface, it is both reflected and absorbed. Depending
upon the construction of the surface, the amount of reflected and absorbed sound differs; soft porous
surfaces like drapes, curtains, or acoustical tile, absorb more sound than hard surfaces. The ideal
location to record absorbs sound very well and is acoustically dead and echo free (fig 1-13).
