RT60 Calculator

This calculator allows you to estimate the reverberation time (RT60) of a conventional room. This is done by using the Sabine's formula. Just enter the room's dimensions and the most significant material of each wall, floor and ceiling. The wall number is irrelevant for the calculation. All calculations are made in metric system.
