Reverberation time 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.

Reverberation time is not limited to indoor spaces as it exists in forests and other outdoor environments where reflection exists.

Reverberation time occurs naturally when a person sings, talks, or plays an instrument acoustically in a hall or performance space with sound-reflective surfaces.

Reverberation time is applied artificially by using reverb effects, which simulate reverb through means including echo chambers, vibrations sent through metal, and digital processing.

Reverberation time is a significant source of mistakes in automatic speech recognition.

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.

Reverberation time is frequently stated as a single value if measured as a wideband signal.

Reverberation time found that the reverberation time is proportional to room dimensions and inversely proportional to the amount of absorption present.

Reverberation time effects are often used in studios to add depth to sounds.

Basic factors that affect a room's reverberation time include the size and shape of the enclosure as well as the materials used in the construction of the room.

Reverberation time is usually stated as a decay time and is measured in seconds.
| FactSnippet No. 2,521,957 |
Concept of reverberation time implicitly supposes that the decay rate of the sound is exponential, so that the sound level diminishes regularly, at a rate of so many dB per second.
| FactSnippet No. 2,521,958 |
Reverberation time proposed to measure, not the power of the sound, but the energy, by integrating it.

Reverberation time established a relationship between the T60 of a room, its volume, and its total absorption.

Sabine concluded that the reverberation time depends upon the reflectivity of sound from various surfaces available inside the hall.
