A room is said to be acoustically 'dead' when it contains a great deal of sound absorbing material, such that there is little or no REVERBERATION, and strong ATTENUATION of high frequencies. The extreme of this situation is the ANECHOIC CHAMBER.
Sound in a dead room will be dull and lack PRESENCE. Sound in the reverse situation is called 'live' or 'brilliant' (see ECHO CHAMBER).

chamber.
