Description
Technical field
The present invention relates to a kind of hearing aids, relate in particular to a kind of noise reduction hearing aids that can reduce environmental noise greatly.
Background technology
Hearing aids is that all help hearing disabilities person to improve dysacousis, and then instrument, unit and the instrument etc. of raising and his conference communicative competence.All in a broad sense various devices that can be effectively import sound into ear can be seen hearing aids as; Say on the narrow sense that hearing aids is exactly an electroacoustic amplifier; The deaf person had been heard originally the sound amplification through it and can not hear clearly, unheard sound, this device is exactly a hearing aids.Hearing aids a multitude of names, but all hearing aidss all must comprise microphone, amplifier and receiver three big parts.
Wherein microphone is an acoustic-electrical transducer, changes extraneous acoustical signal into the signal of telecommunication, makes acoustic pressure be amplified to 10,000 and even several ten thousand times behind the input amplifier, the acoustical signal after this amplifies through receiver output again.Hearing aids should comprise that also power supply is to promote machine works.Because heterogeneity, acoustic trauma function difference in various degree are also different, therefore install equipment such as volume is regulated, tone is regulated, maximum acoustic output adjusting, telephone pickup, and O-M-T (shutoff-microphone-phone) third gear switch all is indispensable.Also be provided with peak clipping (PC) or automatic gain control (AGC) device in addition, to be fit to the human needs of various deafness disease in various degree.
The deafness patient overwhelming majority is the phonosensitive nerve deafness, and wherein considerable people has the positive phenomenon of regeneration.They listen to little sound and feel difficulty, but the sound that rings slightly is difficult to again stand, and the dynamic range of the sensation of loudness is obviously dwindled.Owing to adopt automatic gain control (AGC) or peak clipping (PC) circuit to realize compression and amplitude limit function on the electronics, overcome dysacousis so that this type deaf person uses hearing aids more satisfactorily.
Publication number is CN 1771761, and this hearing aids comprised: a shell for the Chinese patent document of 2006.05.10 discloses a kind of hearing aids in open day; Be used to receive at least the first microphone of background sound; Be used to handle Signal Processing device from first microphone, and output transducer, at least one additional microphone is placed in the hearing aids shell; Between the normal operating period of hearing aids, its present position has shielded the influence of wind.This invention can shield general trickle wind sound, but does not but have the noise reduction effect for other noisy sounds, can not well shield.
Summary of the invention
The present invention is intended to be directed against the well defective of shielding noise of above-mentioned prior art, and the noise reduction that a kind of shielding noise is effective and power consumption is little hearing aids is provided.The present invention has that shielding noise is effective, the characteristics of comfortable wearing degree height and advantages of small volume.
The noise reduction hearing aids; Comprise housing, be arranged on battery compartment, programming hole, loud speaker and microphone on the housing, be arranged on a plurality of digital signal processor ports in the housing; Programming hole, loud speaker and microphone are electrically connected with each port of digital signal processor respectively; Battery in the battery compartment is electrically connected with loud speaker, digital signal processor and programmable device, and it is characterized in that: also be provided with denoiser on the housing, denoiser is fixedly connected on the housing; Said denoiser comprises noise reduction module, power supply and switch, and said noise reduction module is electrically connected with power supply and switch respectively.
The inner surface of said housing adheres to has liner, and the below, bottom of liner is provided with the infrared film electric heating cloth of polymerization of tiling.
The preparatory amplifying circuit of series connection successively of the output linking number word signal processor of said microphone; Mould/number conversion circuit, time domain/frequency domain change-over circuit, wide dynamic range compression processing circuit, noise reduction process circuit, frequency response control circuit; Frequency time domain treatment circuit, frequency domain/time domain change-over circuit; The D/A switch circuit, output attenuatoin circuit, terminating loud speaker.
Said digital signal processor is Toccata chip I TK-100 or the ToccataPlus chip of Dspfactory.
Said housing is duct-type or hard of hearing formula or inner ear type or dark duct-type.
The present invention is through meticulous frequency response control and channel width dynamic range compression Characteristics Control; Add noise reduction module, can reduce noise greatly, good coupling listens to barrier person's hearing loss situation; Fully hearing is tested the requirement of joining, thereby the hearing loss of recovering the user better improves its speech intelligibilty.The present invention can select the noise reduction module of different capacity to arrange in pairs or groups with it through the hearing situation of different people, can bring shield effectiveness preferably to people.And housing employing duct-type or hard of hearing formula or inner ear type or dark duct-type, can satisfy different human needs.
