Rt60 reverb

Reverberation time, or RT60, is a metric which describes the length of time taken for a sound to decay by 60 dB from its original level. Optimal reverberation times vary depending on room volume, intended use of the space and the frequency of transmitted sound.

What is a good RT60 for a control room?

So what is a good RT60 for a control room or a recording room? Well, there isn't just one answer for the latter (drums tend to sound good in large rooms) but for your control room, about 0,3 seconds seems to be agreed upon as a good number.

Why 60dB is used for reverberation time?

Rationale for 60dB Reverberation Time

The choice of the relative intensity to use is of course arbitrary, but there is a good rationale for using 60 dB since the loudest crescendo for most orchestral music is about 100 dB and a typical room background level for a good music-making area is about 40 dB.

What is an RT60 test?

RT60 is a measure of how long sound takes to decay by 60 dB in a space that has a diffuse soundfield, meaning a room large enough that reflections from the source reach the mic from all directions at the same level.

What is a good reverberation time?

Recommended reverberation times for typical spaces any architect needs to know. 0.4 sec reverberation time. Absorbers should be close to the noise, impact resistant and washable. 0.7 – 0.4 sec reverberation time.
