Active noise reduction techniques may also be referred to as electronic technology noise reduction or Active Noise Control noise reduction.The common way of this technology is on headset, install one piece of Dolby circuit chip additional, and installs one piece of cell powers on headset.The scope of general noise reduction is: 100 to 1000HZ.Also have now and claim and can accomplish that noise reduction scope is at 100 to 3000HZ, but actual effect is still to be tested.The noise reduction degree of depth, generally at 12 to 18 decibels, also has and declares to accomplish 30 decibels.
Active noise reduction techniques has good effect for elimination low frequency noise.But it is just not ideal enough for elimination high frequency sound wave effect.In addition, initiatively Active Noise Control noise reduction technology has good noise reduction for the background noise of often appearance and constant appearance, for random appearance, audio frequency fluctuation is indefinite, the noise that the sound intensity is suddenly big or suddenly small, its noise reduction efficacy obviously declines, and time particularly acoustic reception is to the system of liking instead of people, the mistake caused is particularly evident.
For noise reduction headset the deficiencies in the prior art, the utility model proposes the structural measure of oneself, better noise reduction is reached by the innovation of structure, especially the acoustic information after noise reduction is provided to electronic system, desirable noise reduction can be obtained, be beneficial to the voice order that electronic system efficient identification is legal, reduce wrong identification.
