How to Use This Calculator

Enter Room Length, Room Width, and Room Height.
Set Wall Material and Instrument Volume.
Review RT60 (Reverb Time) (sec) and Acoustic Panels Needed.
Use Room Volume (cu ft) and Wall Transmission Loss (dB) to inform your decision.
Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Room Height

Room Height	RT60 (Reverb Time)	Acoustic Panels Needed
7.4	1.54 sec	13
11	1.79 sec	20
15	1.96 sec	28
19	2.08 sec	36

What each input means

Room Length: Length of the practice room in feet.
Room Width: Width of the practice room in feet.
Room Height: Ceiling height in feet.
Wall Material: 1=Drywall, 2=Concrete, 3=Wood. Affects reflection and sound isolation.
Instrument Volume: Typical sound level of your instrument (e.g., violin=85dB, trumpet=95dB, drums=110dB).
