Abstract
Introduces the principles of volume adaptive control at worksite, this system uses C8051F340 as processor, adopting the technology of audio signal sample compare and feedback control. Emphasis is put on analog circuit of audio signal sample, including Pre-amplifier, effective value transform, Sound pressure level and Power Management can save energy. The experiment indicates this system collection truly and high precision. Have good social values and applications future.
