How to Use This Calculator

Enter Width (ft), Depth (ft), and Height (ft).
Set Wall treatment (%) and Treatment thickness (in).
Review the RT60 (seconds) result.
Use RT60 rating (1-3) and Treated area (sq ft) to inform your decision.

How the result changes with Wall treatment (%)

Wall treatment (%)	RT60 (seconds)
10	0.42
35	0.16
65	0.09
90	0.07

What each input means

Width (ft): Booth interior width.
Depth (ft): Booth interior depth.
Height (ft): Booth ceiling height.
Wall treatment (%): Percentage of surfaces with acoustic treatment.
Treatment thickness (in): Foam/fiberglass panel thickness.

What each result means

RT60 (seconds): Reverberation time (target 0.2-0.4s for vocals).
RT60 rating (1-3): 1 = Too reverberant, 2 = Acceptable, 3 = Ideal.
Treated area (sq ft): Total area covered with treatment.
Total absorption (sabins): Combined absorption capacity.
Lowest standing wave (Hz): Frequency of first problematic resonance.
Material cost ($): Estimated acoustic treatment cost.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Width (ft) = 6, Depth (ft) = 6, Height (ft) = 8, Wall treatment (%) = 80 = 5 input(s) provided
Calculate RT60
RT60
0.08 = 0.08
Calculate RT60 rating
RT60 rating
2 = 2
Calculate Treated area
Treated area = round(surfaceArea * wallTreatmentPct / 100)
211 = 211
