Room acoustic calculation
Reverberation and absorber-area calculator
Estimate the additional absorption required to move a room from an entered current reverberation time toward a target condition.
Sabine-method estimate
25.4 m² treatment area
Approximate additional absorber coverage required to move from the entered current reverberation time toward the target.
Room volume153.6 m³
Current absorption13.74 sabins
Target absorption35.33 sabins
Additional absorption21.59 sabins
This is a first-pass statistical estimate. Frequency-dependent measurements, room shape, occupancy, furnishing and actual product data affect the final design.
Use measured data where possible
The current RT60 input should preferably come from site measurements. The result is a broad-band planning estimate and does not replace octave-band analysis or product-specific absorption coefficients.
