Reverberation time is usually stated as a decay time and is measured in seconds .
There may or may not be any statement of frequency bands used in the measurement.
Decay time is the time it takes the signal to diminish 60dB below the original sound.

Reverberation, in psychoacoustics and acoustics, is a persistence of sound after the sound is produced. A reverberation, or reverb, is created when a sound or signal is reflected causing numerous reflections to build up and then decay as the sound is absorbed by the surfaces of objects in the space – which could include furniture, people, and air. This is most noticeable when the sound source stops but the reflections continue, their amplitude decreasing, until zero is reached.
