Description
Technical field
The present invention relates to the cochlear implant field, specifically, the present invention relates to a kind of electricity irritation auditory tone perception test and evaluating system.
Background technology
The cochlear implant technology is present unique neural prosthesis that can allow the deaf person recover audition, by directly stimulating acoustic nerve with electric current, makes the deaf person recover audition, has helped the whole world audition that surpassed the recovery in various degree of 120,000 electronic cochlea implant persons.As shown in Figure 1, the artificial cochlea is comprised of external machine parts and implant component two parts, wherein external machine parts mainly comprise microphone (such as mike etc.), speech processor and transmitting coil, and implant component comprises that mainly receiving coil, processor, stimulating electrode and reference electrode form.Connect in the normal situation in system, mike receives acoustical signal, by the speech processor, acoustical signal is carried out analyzing and processing and coding, see through the receiving coil that skin is sent to implant component by a part (transmitting coil), after the decoding processing through stimulator, the pulse signal that produces corresponding frequencies and current intensity also is sent to each stimulating electrode.By the electrode stimulating acoustic nerve, thereby being passed to auditory center, pulse signal produces audition for user.
The perception of electricity irritation auditory tone is the theoretical basis of cochlear implant simulation people ear function.About about 3000 ciliated cell is arranged in normal person's the cochlea, be tuned on respectively from the different frequency between 20～20, the 000Hz, simultaneously, 10～20 nerve fibers that stimulate audition are arranged in each ciliated cell, and they pass information to the central nervous system.According to place coding, the different frequency information of sound is by different auditory channel transmission.Suppose that each nerve fiber is a frequency transmission passage, than the frequency transmission path that a limited number of electrode of present cochlear implant (8～22) can provide, normal human ear can provide frequency discrimination force rate cochlear implant will exceed several orders of magnitude.Because at present electrode manufacturing technology and the how restriction of electrodes technology in cochlea, be difficult to increase again the quantity of implant electrode.This also just means, from the angle of signal processing strategy, fully according to place coding, is difficult to improve the frequency resolution of cochlear implant.Psychoacoustics experiment showed, time encoding the chances are in electricity irritation that stimulation rates simulates by changing, and its limited range is 300～500Hz.That is to say, under the prerequisite that electrodeplate does not increase, might encode to improve by conversion SR simulated time the frequency resolution of cochlear implant.
Abroad the research of electricity irritation auditory tone perception is started from Cochlear company and the test of a series of cooperations of the University of Melbourne eighties in last century, representative is the electricity irritation auditory psychology acoustical testing that the people such as Clack and Tong utilize the Cochlear product to do.After 2000, because the cochlear implant product is universal, the cooperation of cochlear implant company and R﹠D institution is strengthened day by day, and the research of electricity irritation auditory tone is developed rapidly at US and European.As a basic research, the perception of electricity irritation auditory tone is helping to have obtained certain achievement aspect the explanation human auditory mechanism; As the cochlear implant correlational study, the perception of electricity irritation auditory tone is being instructed and the development of revising cochlear implant acoustic coding strategy.At present external research to the tone perception is developed to the objective evaluation aspect in conjunction with brain electricity testing of equipment by traditional subjective psychology acoustical testing to implantation person.。
