English: Very simplified diagram: sound level in a reverberant cavity excited by a pulse, as a function of time. RT60 is the reverberation time. The small variations (small vertical peaks) of the pressure along the lines are not shown.
Reverberation time is a measure of the time required for the sound to "fade away" in an enclosed area after the source of the sound has stopped. When it comes to accurately measuring reverberation time with a meter, the term T 60 [6] (an abbreviation for reverberation time 60 dB) is used. T 60 provides
A perfectly diffusive sound space is one in which the reverberation time is the same at any listening position. Most interior spaces are non-diffusive; the reverberation time is considerably different around the room. At low frequencies, they suffer from prominent resonances called room modes.
For example, in architectural acoustics the rectilinear trajectories of sound rays make it possible to determine reverberation time in a very simple way. The operation of fathometers and hydrolocators is based on measurements of the time required for sound rays to travel to a reflecting object and back. The ray concept is used in designing ...

If the third letter is F, S or I, this represents the time weighting, with F = fast, S = slow, I = impulse. [14] Time weighting is applied so that levels measured are easier to read on a sound level meter. The time weighting damps sudden changes in level, thus creating a smoother display. The graph indicates how this works.
