critical distance

critical distance is from the sound source where the direct and reverberant sounds clash and become equal. the more reverberant is the closer the critical distance is to the main sound source.

the critical distance will be different at all frequencies and venue.











critical distance should be as far away from the source of sound as posse;e and reverberant to a minimal keeping it even at all frequencies.

an easy way to figure out the critical distance is to play pop music through one speaker, and walk back and forth the room, this will be surprisingly easy to spot.














the more reverberant the room is the closer the critical distance
the more absorbent the room the further the critical distance
near field or direct field is inside the critical distance
far field or reverberant field is outside he critical distance
