Reverberation Time in Room Acoustics - Larson Davis

Reverberation time is the time after the source of the sound has ceased that it takes the sound to fade away. How can we make objective measurements of reverberation? We use the metric Reverberation Time 60 (RT60). RT60 is defined as the measure of the time after the sound source ceases that it takes for the sound pressure level to reduce by 60 dB. Why 60 dB?

The reverberation time is the time the sound pressure level takes to decrease by 60 dB, after a sound source is abruptly switched off. Commonly-used abbreviation for reverberation time are T or RT60. Reverberation Time values vary in different positions within a room.

For average control room volumes, preferred reverberation times fall into the 0.3 to 0.4 second range. In recording studios the reverberation times are variable, and range between 0.8 and 1.5 seconds, depending on the size of the room. Figure 21.10 gives a number of values based on room volume and the type of music.
Recommended reverberation times for 7 key spaces

0.8 – 0.7 sec reverberation time. Use absorbers on 50-70% on the ceiling and wall absorbers corresponding to 10-20% of the ceiling area. Finding the right reverberation time is not easy. Now watch out. Creating the perfect sound in a room is not always as easy as that. Just be aware that there are a lot of interfering factors to be considered.

The Reverberation Time - T a-for a room is the time it takes before the sound pressure level has decreased with 60 dB after the sound source is terminated and can be calculated as. Mean sound absorption coefficient α m <= 0.35: T a = 0.16 V / A (1) where. T a = reverberation time (s) V = room volume (m 3)

We should be conscious that reverberation time is an important issue because it's really inconvenient to stay in a room where it is too high. Now you will be able to check it yourself following these steps: 1. Find a maximum value of dB's in our array 2. Slice data and time arrays to the point where you found a maximum value 3.
Reverberation Time RT60 Measurement - Dewesoft

Reverberation is a key parameter when qualifying the acoustic status of a room. Evaluation Range Reverberation time can be evaluated based on a smaller dynamic range than 60 dB and extrapolated to a decay time of 60 dB. The evaluation of the decay curve for each frequency band shall start at 5 dB below the initial sound pressure level.

The preferred reverberation time range for a space intended for speech is 1.0 second, or less. As the reverberation time (or RT60) becomes longer than that, it becomes increasingly difficult to understand unaided speech, and if it is much shorter the room sounds very dead. As the RT60 gets much longer, 3, 4, or even 5 seconds, speech becomes impossible to understand.

Strong or prolonged reverberation can occur when a comparatively long time passes before the sound level, after the actual sound event, has subsided. An echo – such a strongly delayed reverberation of a sound event that we perceive it as an entirely independent sound event – occurs rarely in a normal house. To cause such a long delay, the distance between the ear and …
