Which foam acoustic panels should I use for a sound booth?


       Good evening everyone, I hope that you all are doing well. I just finished building a voice and sound booth that is 4'x4'x7' made from 1/2" gypsum drywall with a pine frame. With there being so many options for panels, as well as do it yourself alternatives such as making panels from Rockwool and owen corning 703 (Here is the NRC reference for such materials https://www.bobgolds.com/AbsorptionCoefficients.htm), I am uncertain with what I need to get. If I can build them myself without any loss of quality then I would prefer to take that route. Does anyone have any experience or any recommendations for where to begin in this matter? I hope that this is the right topic thread to post this in and I thank you very much for your time and effort.

Have you read 'Master Handbook of Acoustics' by F. Alton Everest?

It's a modern classic. Suggest you use it to determine what you need, and then find a local insulation distribution warehouse. 

I'm using Primacoustic panels in my dedicated listening room. Very pleased.

Owen Corning 703 really works, it absorbs down to lower frequencies than most foam or wool.  It's whats  inside ready acoustics sound panels. 

SONEX acoustic foam and similar foam, even the foam used in the ubiquitous IKEA Puang Chair, are very bad for the sound. It seems like such a good idea, too. Nice charcoal gray or black sculpted foam, just like they have in the control rooms of recording studios. SONEX might be the single worst audio product ever foisted on naive, earnest and gullible audiophiles.
