This sound pressure meter did exactly what I asked it to do: tell me if the volume of my 5.1 home theater speakers was the same after Audyssey calibration, measured from my #1 seat; had not. Using the "Tuning" mode of my receiver, I was able to send out the tones, measure them and, if necessary, adjust the volume of the loudspeakers to up to 75 dB. Five minutes and you're done! The noise level did not drop significantly, but the improvement achieved was noticeable. Thank you VLIKE!
