FIG. 1 is a schematic view of the present invention.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the described embodiments are only some, and not all, embodiments of the invention. Based on the embodiments of the present invention, those skilled in the art can obtain all other embodiments without creative efforts, which belong to the protection scope of the present invention.
A self-fitting system for a hearing aid includes two parts, a hearing aid and external software. The hearing aid part comprises a speech amplification process and a sinusoidal signal generator module part. The voice amplification processing is a digital signal processing system, and the hearing test module is arranged in the digital signal processing system. The external software part consists of hearing test and programming software. Testing, programming are intelligent, adopt digital signal processing system, also embed in the APP and have sinusoidal signal generator unit to the corresponding APP of cooperation PC or cell-phone end just can realize testing at any place oneself, need not the testing and matching personnel of external equipment, specialty, very big has made things convenient for hearing impaired crowd and old user, has simplified the testing and matching procedure, has realized self-testing and matching.
In the digital signal processing system, after a target hearing-impaired patient is subjected to accurate hearing test, a corresponding hearing analysis compensation map can be obtained. The hearing-impaired patient does not need to place the transmitted pure tone and the like on another device for operation such as fitting and the like through a fitting teacher. The hearing-impaired patient can directly wear a hearing aid earphone to listen to sound, the compensation form provided in the digital signal processing system is matched with the fitting software of the APP software corresponding to the PC or the mobile phone terminal, self fitting in any place can be realized, and the compensation effect is experienced through a listening program, so that the difference of the parameters of external test equipment is avoided. The hearing aid is an earphone in the same hearing aid, so that the testing, testing and matching process is simplified, and the accuracy of the hearing test is improved.
The external software part is installed in a PC or a mobile phone end APP or a special hearing aid fitting box, and the interface of the external software part also comprises main buttons such as retesting, determining, storing and hearing soft keys. The retest button can be used for retesting or fitting according to the self fitting condition or feeling that the fitting is not ideal when the user uses the device.
The PC or the mobile phone end APP is connected with the hearing aid in a wired or wireless mode, then pure sound signals with different frequencies and different gains are sent out by a built-in sine signal generator of the hearing aid through hearing test software, finally, sound is sent out through an earphone in the hearing aid, and then the test software respectively sends out frequency point control signals of 125, 250, 500, 1K, 1.5K, 2K, 4K and 8K (Hz). The frequency point can be set by itself, and the volume of each frequency point is started from 20dB (can be set), so that the user can confirm whether to hear a pure tone signal in the hearing aid. If the user can not hear the pure tone signal, the system will increase the volume by 3-5 dB (can be set) in an automatic or manual key pressing mode after 3-10 seconds (can be set). If the user can hear the sinusoidal signal and click the confirmation key, the system will automatically record the hearing threshold (frequency vs. decibel coordinate point of hearing threshold) at a certain frequency point. If the user can not hear the pure tone signal, the system continues to increase the volume by 3-5 dB in an automatic or manual key pressing mode until the user hears and presses a confirmation key.
And by analogy, the test software sends out 125, 250, 500, 1K, 1.5K, 2K, 4K and 8K (Hz) frequency point control signals in turn to reach the audible range of the user, and after the user hears the frequency point control signals, the system automatically records the hearing threshold value of the frequency point by pressing a confirmation key on the software interface.
After the frequency point of the system is measured, the system can automatically generate a hearing loss parameter graph of the user (the system automatically connects each hearing threshold to form a hearing loss compensation graph), the software programming system automatically integrates a fitting formula in the programming system according to the hearing loss parameter graph of the user through a programming equation to calculate a set of related hearing aid parameters suitable for the user, changes all parameters in a hearing aid voice processing system, and an external software part is connected with a self-fitting hearing aid in a wired or wireless mode.
The hearing loss compensation graph is represented by a coordinate graph, wherein the X axis of the graph is frequency, and the Y axis of the graph is decibels and the like. The invention is suitable for all the hearing-impaired people, and greatly facilitates the user to check and match the hearing aid. Moreover, since the degree of hearing loss changes, the self-fitting can be performed irregularly, or again every half year.
Wherein a sinusoidal signal generator in the system sends a tested sinusoidal signal to a user through a hearing aid earpiece, thereby obtaining a hearing loss compensation map. The self-check distribution system can automatically write hearing aid parameters such as frequency, decibel, inflection point, compression ratio and the like according to the data of the hearing loss compensation graph.
Example 2, in contrast to example 1: the built-in hearing test module can be designed in a digital voice processing chip as an independent unit, and can also be designed outside the chip (in an external APP) as an independent unit. The design is in the inside of audiphone, helps reducing occupation space, designs into independent unit simultaneously and lies in the audiphone, and it adopts same audiphone earphone to carry out the hearing test and tests and joins in marriage, simplifies the procedure, avoids the audiphone when collecting relevant data, causes the frequency response curve to mismatch, improves the hearing test, tests the precision of joining in marriage.
The method comprises the following operation steps: the user connects the hearing aid in a wired or wireless mode through corresponding APP software in a PC or a mobile phone terminal. Firstly, a sinusoidal signal generator in the hearing aid emits pure sound signals with different frequencies and different gains through hearing test software, and sounds through an earphone in the hearing aid, and secondly, the test software respectively emits corresponding sound Hertz frequency instructions, and a user can respectively hear sinusoidal signals in the hearing aid. If the user can not hear the sine signal, the system can automatically or manually increase the volume in a key pressing mode within corresponding time until the user hears and presses a confirmation key, the system can automatically record the frequency click threshold after the user hears, finally, the related hearing aid parameters suitable for the user are calculated through a software programming system, and then the related hearing aid parameters in a hearing aid voice processing system are rewritten. If the user feels that the hearing effect is not good, the user can press the retest key button to conduct retest, and after the adaption is completed, the user presses the hearing and please click the key on the software interface. When the device is used next time, the switch is directly turned on, and if the hearing loss degree changes, the test needs to be performed again.
