Abstract

The invention discloses an automatic fitting digital hearing aid which comprises a voice picking device, an A / D (Analogue / Digital) converting device, a microprocessor for carrying out data processing on a first digital signal, a D / A converting device for converting an acquired second digital signal into a second analogue signal as well as a voice output device, wherein the microprocessor comprises a voice gaining and signal noise processing module, a key inputting module, an acoumeter, an audiometry program module, an automatic fitting module and a storage module; the key inputting module is used for determining whether to enter an acoumeter mode for automatically fitting; the acoumeter is used for determining the hearing loss condition of a patient; the audiometry program module is used for obtaining audiogram information of the patient; the automatic fitting module is used for automatically fitting the output result of audiometry program to determine a compression threshold, compression ratio and other parameters of the hearing aid; and the storage module is used for storing relevant data and parameters of the program. According to the automatic fitting digital hearing aid disclosed by the invention, a fitting formula is integrated to a DSP (Digital Signal Processor) chip and is planted into a hearing aid body. The automatic fitting digital hearing aid has the characteristics of convenience in wearing, high distinguishing efficiency, accuracy in fitting, effective protection of residual hearing and the like.

Description

technical field [0001] The invention relates to a hearing aid, in particular to an automatic fitting digital hearing aid and a method thereof. Background technique [0002] Hearing impairment is a common disease that seriously hinders people's life, study and work. Since hearing impairment, people hope to cure it. After repeated efforts, when the hope of curing some hearing impairments becomes very slim, people are eager to help hearing impairment through a hearing compensation method other than drugs or other treatments. Patients improve and improve their hearing. With the improvement of people's living standards and the popularization of health awareness, the incidence of hearing loss is decreasing year by year. With the development of otology, most hearing loss can be cured by medicine or surgery, and the hearing can be preserved or improved to a certain extent. However, for patients with neurological hearing loss, there is currently no clear and reliable drug or surgic...
