Jeff traveled to China to inspect and test the new design of the SPB33 Soundproof(er) vocal booth. Here he tests with Jenny, the Chinese production manager at the manufacturer. They place a very loud stereo outside the booth and measure the SPL difference inside and out. Then placing the stereo unit inside the booth and measure again in both places to see and hear the results. Hear for yourself!
