What exactly we calculate

Reverberation is why a room sounds bad

Hard walls, glass and concrete reflect sound. Voices blend, noise rises and people get tired. Reverberation time RT60 tells how long a sound takes to fade.

From dimensions, surfaces, furnishings and occupancy, ReverbCheck calculates reverberation in six frequency bands and compares it with the target for the room type.

The closer to the green band, the more pleasant the acoustics.
