Self-fitting system of hearing aid

Abstract

The invention relates to the technical field of hearing aids, and discloses a self-fitting system of a hearing aid. Comprising a hearing aid body and an external APP, a sine (pure tone) signal generator is arranged in the hearing aid body and can generate sine wave signals with different gain values at different frequency points, and self-sensing and compensation effect experiencing are carried out through a compensation mode provided by the hearing aid body in a digital signal processing system in cooperation with PC or mobile phone App fitting software, so that the hearing aid body can be applied to the hearing aid body. A hearing-impaired patient directly uses a hearing aid earphone to carry out a self hearing test, the fitting system writes corresponding parameters such as frequency, decibel, inflection point and compression ratio according to data of the self hearing test, and various tests do not need to be carried out through an external device. According to the hearing aid, the difference of parameters of external test equipment is avoided through the internal digital signal processing system, the built-in hearing test module and the use of the hearing aid earphone, so that the test fitting and the hearing aid adopt the same loudspeaker in the hearing aid, the fitting procedure is simplified, and the accuracy of the hearing test fitting is improved.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a self-fitting system for hearing aids. Background technique [0002] Hearing aids are mainly composed of three main parts: movement, casing, and sound guide tube. According to its shape and structure, it is divided into deep-in-the-canal (IIC), in-the-ear (CIC), half-in-the-ear (MITE), completely in-the-ear (ITE), behind-the-ear (BTE), and box (PCT); The channels are divided into 1 to 32 channels. This hearing aid is suitable for hearing impaired persons with residual hearing range of 30dB to 120dB HL. [0003] A traditional hearing aid is a simple device that amplifies sound and processes speech. If it is to be debugged and programmed, special external equipment is required: audiometer (test equipment for the degree of hearing loss, pure tone signal generator and control part), programmer, fitting software on the computer, and connecting line. There are many eq...

Problems solved by technology

This brings great inconvenience to hearing-impaired people, especially for users in remote areas.

Moreover, due to the differences in test equipment and hearing aid parameters, the fitting effect will bring different degrees of deviation, which will easily lead to the incomplete and accurate matching of hearing aid fitting and hearing-impaired patients, thus affecting the accuracy of hearing aid test fitting.
