WebJun 24, 2005 · Head Shadow. Just as our head blocks light (and our parents’ advice), it also blocks sound traveling through the air. This creates an acoustical shadow behind the head; an area with greatly reduced sound energy. Small objects only reflect high- frequency sound waves with short wavelength. Larger objects, on the other hand, reflect low ...
