Results

Target RT60 (seconds)

0.8

Acoustic panels (sq ft)122

Volume adequate (0/1)1

Wall distance OK (0/1)1

Bare room RT60 (seconds)2.1

Remaining floor space (sq ft)222

How to Use This Calculator

Enter Room length (ft), Room width (ft), and Room height (ft).
Set Piano type (1-3) and Teaching room (0/1).
Review the Target RT60 (seconds) result.
Use Acoustic panels (sq ft) and Volume adequate (0/1) to inform your decision.

What each input means

Room length (ft): Room length.
Room width (ft): Room width.
Room height (ft): Ceiling height.
Piano type (1-3): 1 = Upright, 2 = Baby grand, 3 = Concert grand.
Teaching room (0/1): 1 = used for piano lessons (needs more clarity).

What each result means

Target RT60 (seconds): Recommended reverberation time.
Acoustic panels (sq ft): Treatment needed for target RT60.
Volume adequate (0/1): 1 = room large enough for piano type.
Wall distance OK (0/1): 1 = enough clearance from walls.
Bare room RT60 (seconds): Untreated room reverberation time.
Remaining floor space (sq ft): Floor area after piano placement.
