(S.) One says, صَمَّ صَدَاهُ (tropical:) [ His echo became dumb, or may his echo become dumb ]; (S, TA;) meaning he perished, or may he perish: (S and K and TA in art. صم:) and أَصَمَّ ا@للّٰهُ صَدَاهُ (tropical:) [ May God make his echo to return no sound ]; (S, K, TA;) meaning may God destroy him: (S, K, and TA in art. صم:) for when a man dies, the صدى hears not from him anything, that it should respond to him.

(TA.) ― -b3- Also The part of the head, (M,) or the part of the brain, (TA,) which is the place [or seat ] of hearing. (M, TA.)
