This term refers to sound arriving on a direct acoustical path from the source to the listener in an enclosed space (i.e. with no intervening reflections from boundaries). The direct sound is the desired signal for a speech reinforcement system. (See also direct-to-reverberant ratio, reverberation, signal-to-noise ratio, masking.) Return to
Sound that reaches the listener location by direct line-of-sight, without being reflected off any surface or transmitted through any material, and thus is unaffected by the room conditions.
The sound that's heard straight from the source and has not been reflected off another surface. Direct sound is clearer than reflected sound.
