I’ve identified a potential sound-proofing unit, with a base price of about $7400.00.
The booth reduces 125 Hz sound by 30 dB, which is rather good for such a small unit, but what I need to know now is, what exactly can be done increase the noise reduction? Foam panels? Rubberized mats? Putting the booth on stilts?
I need an experienced audio technician or audio engineer to help this move forward. Once I’m satisfied with these answers, then I will purchase the unit as soon as the funds become available.
