this time calculated is the relative background noise decibel value, if the user does not sound the microphone, calculated the basic is 0 decibels. And the user actually use the scene background noise size varies widely, if we also divert is not right, especially for those who make absolute decibel demand, should find 20 micro-pa sound pressure value corresponding amplitude (or can also take a standard decibel meter for calibration reference).Bo Mast

, the decibel value of the relative background noise is calculated. If the user does not correctly sound the microphone, the basic figure is 0 decibels. The background noise size of the user's actual scene varies widely. It's not right if we divert.
