acoustic shadow [ə′küs·tik ′shad·ō]

(acoustics)

A region immediately behind an object placed in the path of a sound wave whose wavelength is much smaller than the object, in which the initial sound wave is cut off by the object and the sound intensity is determined by the diffraction and interference of sound waves bent around the obstacle.

Jaudon-Bosch. (2003 Wedding Register) by Mississippi Magazine Millili stated, "Regardless of observer experience in burn evaluation, obliteration of the dermal/fat interface and widening of the dermal acoustic shadow provides reliable markers of deep thermal injury.
