What causes reverb? ... Contrary to popular belief, egg crates do almost nothing to stop reverberation. Absorbing sound generally requires mass, something egg crates have very little of. Carpet will help to some degree, though it tends to absorb only the highest frequencies.

it is this reflection that causes reverb to occur. Reverberation helps maintain the energy of a sound and the distribution of the sound to the listener. While outside equipment can accentuate or enhance already-existing reverb, there is always some degree of reverb taking place when someone speaks or plays an instrument.

Too much reverberation causes sounds to become confused and indistinct, and this is particularly noticeable in empty rooms and halls, and such buildings as churches and cathedrals where the hard, unfurnished surfaces do not absorb sound energy well.

This causes the reverberation times in these rooms to be longer in the low frequency range than in the midrange or high frequency ranges. The thick red line in the diagram above shows an example of a room which would be perceived as ideal.

Complexity of Exact Reverberation; Reverberation time is typically defined as t60, the time, in seconds, to decay by 60 dB. Example: • Let t60 = 1 second; • fs = 50 kHz; • Each filter hij requires 50,000 multiplies and additions per sample, or 2.5 billion multiply-adds per second.

(Reverberation causes energy to spread to new, later places in the t-f grid. Additive noise adds energy.) The rule of thumb is there should not be energy in a t-f cell in the output that was not in that cell in the original (input) signal.
