What is RT60?

RT60 is a traditional metric used to measure reverberation time, specifically, how long it takes for sound energy to decay by 60 decibels after a sound source stops. While it is often viewed as a dead-room goal, we treat RT60 as a clarity metric. In large rooms such as concert halls, managing long decay times is essential for speech intelligibility and musical detail. However, in recording studios and smaller listening spaces, the raw number matters less than balance across the frequency range,
