An untreated bedroom studio has relatively high reflectivity; this calculator shows how absorption panels reduce the RT60.
Frequently asked questions
- What is RT60?
- RT60 is the time (in seconds) for a sound to decay by 60 dB after the source stops. A concert hall typically has RT60 of 1.5–2.5 s; a recording studio aims for under 0.5 s.
- What is Sabine's formula?
- RT60 = 0.161 × V / A, where V is room volume (m³) and A = surface area × average absorption coefficient.
