About it

Reverberation is sound that keeps bouncing around a room after its source stops. RT60 is the time for its energy to fall by 60 decibels, to one millionth. This splash estimates that time from a measured decay slope, extrapolating when it cannot observe the entire 60-decibel fall; background noise and the recording affect the result.

Tap the splash to hear and see the sample room's clap. For your room, tap Use my microphone in the Splash tab, clap sharply once and stay quiet for two seconds. The page estimates background noise and fits the sound's fading energy. The back wall shows the result; floor rings visualize the decay at half speed. A noisy or unclear clap may be rejected. Audio is processed temporarily on this device and is not uploaded or saved. This is an exploratory estimate, not a calibrated room-acoustics measurement.
