, 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. Especially for those who make absolute decibel, should find the 20 micro-pa sound pressure corresponding amplitude (or can also take a standard decibel meter for calibration).Bloggers are more lazy, set th

When the volume button in Android is turned down, if you keep holding down the down button, the system will jump to a minimum and then automatically adjust to mute. This mechanism and iphone is different, the iphone no matter how you press the volume-button, can only be adjusted to the smallest, or a little voice, is not automatically mute.Android If you want to

By learning Android Deep Exploration (Volume one) HAL and Driver Development Chapter Sixth let me understand the complete process of developing and testing Linux drivers for counting the number of words.The Linux system maps each driver into a single file, which is called a device file or driver file, and is stored in the/dev directory.

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

time to calculate the relative background noise decibel value, if the user does not sound to the microphone, the calculation of the basic is 0 db. And the user actual use scene background noise size is very different, if I also divert is wrong, especially for those who make absolute decibel requirements, should find 20 micro-PA value corresponding to the amplitude (or can also take a standard decibel meter to do calibration reference).
