Each of us knows that characteristic resonance of sound in a great cathedral or on a staircase. It's a phenomenon that can add majesty to music, but in an office or a school, it becomes the greatest enemy of communication. What exactly is this "tail" that follows the sound?

Professional Definition

The disappearance of sound in a room after the sound source has been turned off, as an effect of multiple sound reflections occurring.

Physically, reverb is the sum of all reflections of the acoustic wave from obstacles in the room that reach the listener with a delay compared to the direct wave. The primary parameter describing this phenomenon is reverberation time (RT60), which is the time required for the acoustic pressure level to drop by 60 dB after the source has been turned off. A long reverberation time degrades the speech transmission index (STI).

Acoustics in Simple Words

Imagine a pool table where a hundred balls are rolling simultaneously. When you strike the first ball (sound source), it hits others and the rails of the table (walls). Even when you stop hitting, the balls will still roll, bounce, and gradually slow down until they come to a complete stop. This time, during which the balls are still in motion despite the lack of new strikes, is what we call reverb. In a room, the sound
