Problems solved by technology

Due to the limitations of current electrode manufacturing technology and how to place electrodes in the cochlea, it is difficult to increase the number of implanted electrodes
This means that, from the perspective of signal processing strategies, it is difficult to improve the frequency resolution of cochlear implants entirely based on part coding

Embodiment Construction

[0030] The technical solutions provided by the present invention are further described below in conjunction with the examples.

[0031] Such as figure 2 As shown, it is a block diagram of the electrical stimulation auditory tone perception evaluation system of the present invention; before the test, first set up as figure 2 The test system shown. The subjects were required to remove the speech processor used in daily use and wear the speech processor dedicated to this test instead. After the system is connected normally, it is ready to start the test;

[0032] Such as Figure 5 As shown, it is a flow chart of the electrical stimulation auditory tone perception test and evaluation of the present invention; first, through the electronic cochlear implanter information input module 11, the tester assists the subject to enter its basic information, including name, gender, age, deafness Cause, duration of deafness, cochlear implant type, etc.; then select the "part" tone test ...

Abstract

The invention relates to an electrical stimulation audition tone perception testing and estimating system. By selecting a part tone testing and estimating module (8), a time tone testing and estimating module (9) or a part-time combined tone perception testing and estimating module (10), the testing and estimation are carried out by combining a testee basic information and electrical stimulation loudness information database (6) with an electrical stimulation audition tone perception experimental database (7); the part tone testing and estimating module (8) is used for testing the correlationbetween an implanted electrode position and electrical stimulation audition tone perception; the time tone testing and estimating module (9) is used for testing the correlation between an electric pulse stimulation rate and tone perception; and the part-time combined tone perception testing and estimating module (10) is used for testing the correlation between electrode position-electric pulse stimulation rate combination and tone perception. The method is accurate and effective.

Description

technical field [0001] The invention relates to the field of cochlear electronics, in particular to an electrical stimulation auditory tone perception test and evaluation system. Background technique [0002] Cochlear implant technology is currently the only neuroprosthetic that can restore hearing to the deaf. By directly stimulating the auditory nerve with electric current, the deaf can restore their hearing. It has helped more than 120,000 cochlear implant recipients around the world restore their hearing to varying degrees. Such as figure 1 As shown, the cochlear implant is composed of two parts, the external machine part and the implant body part, wherein the external machine part mainly includes a microphone (such as a microphone, etc.), a speech processor and a transmitting coil, and the implant body part mainly includes a receiving coil, a processor, Composed of stimulating electrodes and reference electrodes. When the system connection is normal, the microphone re...
