Description
Technical field
The utility model relates to the digital hearing aid equipment technical field, especially a kind of at simultaneously with the patient of hearing loss and tinnitus, tinnitus masker is applied to the digital hearing aids of sheltering in the middle of the digital hearing aid equipment.
Background technology
At present, hearing aids miscellaneous is arranged on the market, dissimilar tinnitus maskers is also arranged, but great majority all have only simple function, promptly hearing aids has only possessed hearing-aid function, and can not tinnitus be sheltered; Tinnitus masker can only be used to shelter tinnitus simultaneously, and can not use as hearing aids.Clinical discovery has the patient of hearing loss, has very high ratio to be accompanied by tinnitus.Hearing aids is by the sound around amplifying, and handles in time domain and frequency domain, with compensation patient's hearing loss, thereby improves speech intelligibilty.Masking treatment tinnitus is to utilize artificial sonic stimulation to suppress tinnitus or the excited enhancing activity of acous spontaneity, suppresses the above nervous centralis pathway of pathology.Tone, frequency and loudness according to tinnitus are regulated masking signal, make it to be complementary with patient's tinnitus feature to shelter purpose to reach.In the clinical practice, sheltering therapy is one of very effective method in the tinnitus treatment.Patient's ratio with hearing loss and tinnitus increases year by year simultaneously, and in order to treat above-mentioned two kinds of diseases, the patient often needs to buy hearing aids, buys again simultaneously and shelters device, still, can not carry out simultaneously when treatment at all, and result of treatment is poor; And need the expense of payment two complete equipments, caused great financial burden, use also inconvenient to the patient.
The utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of at simultaneously with the patient of hearing loss and tinnitus, the digital hearing aids of sheltering of treatment can be provided simultaneously, the utility model result of treatment is good, and is with low cost.
The technical solution adopted in the utility model is as follows:
A kind of digital hearing aids of sheltering, comprise the sound collector of input speech signal, be connected with sound collector and voice signal is converted to the A/D converter of digital signal, signal processor that digital signal is handled, the digital signal after signal processor processes is converted to the D/A converter of analog signal and with the sound transducer of analog signal output, it is characterized in that: be provided with signal synthesizer between described signal processor and the D/A converter, the input of signal synthesizer is connected with the output of masking sound generation device.
Described signal synthesizer is to the digital signal of the voice of importing through signal processor with through synthetic output of the sound masking signal of masking sound generation device input or the independent signal synthesizing module of exporting.
Described masking sound generation device comprises digital noise generator and connected digital filter/digital filter bank, and described digital noise generator is Gassian noise generator or speech noise generator or pink noise generator or narrow band noise generator or their combination.
Be provided with between described signal synthesizer and the D/A converter and switch output voice signal, the signal output dip switch of the mixed signal of sound masking signal or voice signal and masking sound.
Described sound collector is a microphone, and described sound transducer is loud speaker or earphone.
Advantage of the present utility model is:
1, the utility model is provided with signal synthesizer between signal processor and D/A converter, connect masking sound generation device on the signal synthesizer, the sound masking signal of the voice signal of signal processor output and the output of masking sound generation device is by synthetic output of signal synthesizer control or output separately, during synthetic output, to the patient of while with hearing loss and tinnitus, treatment can be provided simultaneously, and existing two complete equipments are the better effects if of treatment separately, and cost significantly reduces.
2, be provided with the signal output dip switch between signal synthesizer and the D/A converter, opening voice processing section and signal synthesizer use as hearing aids as required; Or only open masking sound processor and signal synthesizer, use as sheltering device.Can satisfy different patients' needs.
3, the utility model is simple in structure, easy to maintenance, cost is low, possesses marketing prospect widely.

Embodiment
Embodiment 1
A kind of digital hearing aids of sheltering, comprise the sound collector 1 of input speech signal, be connected with sound collector 1 and with voice signal be converted to the A/D converter 2 of digital signal, the signal processor 3 that digital signal is handled, the D/A converter 4 that will be converted to analog signal and with the sound transducer 5 of analog signal output through the digital signal after signal processor 3 is handled, be provided with signal synthesizer 6 between described signal processor 3 and the D/A converter 4, the input of signal synthesizer 6 is connected with the output of masking sound generation device 7.Described masking sound generation device 7 comprises digital noise generator 8 and connected digital filter/digital filter bank 9, and described digital noise generator 8 is Gassian noise generator or speech noise generator or pink noise generator or narrow band noise generator or their combination.Described signal synthesizer 6 is to the digital signal of the voice of importing through signal processor 3 with through synthetic output of the sound masking signal of masking sound generation device 7 inputs or the independent signal synthesizing module of exporting.Be provided with between described signal synthesizer 6 and the D/A converter 4 and switch output voice signal, the signal output dip switch 10 of the composite signal of sound masking signal or voice signal and masking sound.Described sound collector 1 is a microphone, and described sound transducer is loud speaker or earphone.
Operation principle of the present utility model:
The utility model is handled voice signal by using multiple signal processing technology, the person's that can good coupling listens to the barrier hearing loss situation, and fully hearing is tested the requirement of joining, thus the hearing loss of recovering the user better improves its speech intelligibilty.The utlity model has masking sound generation device 7 simultaneously, can send various masking sounds patient's tinnitus is sheltered, satisfied the tinnitus patient needs and carried out the requirement of masking treatment.The utility model after by 6 pairs of processing of signal synthesizer voice signal and the sound that sends of masking sound generation device 7 to carry out signal synthetic, the synthetic weight of two kinds of voice signals is adjustable.When not importing masking sound, output has only the voice signal after the processing, the function of having only hearing aids of performance.In like manner, during input speech signal, only do not export masking sound, only possess the function of sheltering.When both have input simultaneously, be output as the sound that both synthesize.Whole system also can be passed through signal output dip switch 10, and an opening voice processing section and signal synthesizer 6 use as hearing aids; Or only open masking sound processor and signal synthesizer 6, use as sheltering device.Can satisfy different patients' needs.
Embodiment 2
The utility model is not limited to the foregoing description, and according to the description of the foregoing description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection range of the utility model claim.
