Acrylic Drum Screen Review!(?)

Yea I know....why review a drum screen? Well, I found that I wanted to check one out because I record with other players in a tight space. As a result, they would be literally 1 foot from my kit. I bought a 5 foot high, 5-panel screen to cut down on the volume of the kit. I was curious as to HOW MUCH the volume was cut. I don't have a dB meter so I recorded using 3 room mics and compared the waveform heights in Logic with and without the screen.
