Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0026] Such as figure 1 As shown, the hearing aid self-fitting method includes the following steps:

[0027] Step 1: Establish a knowledge base: the knowledge base contains the personal information of historical patients and the optimal hearing aid algorithm parameters matched with historical patients. Personal information refers to factors related to cognition, including at least gender, age, education level and pure tone hearing test results. Gender, age and education level can be represented by fuzzy values.

[0028] Step 2: Find and optimize the hearing aid algorithm parameters: input the personal information of the current patient into the knowledge base, and match it with the personal in...

Abstract

The invention discloses a hearing aid self-fitting method. The method includes the steps that firstly, a knowledge base is established, a historical patient most similar to a current present is found out, and the optimal hearing aid algorithm parameters of the historical patient are obtained; the current patient conducts satisfaction evaluation on the sound quality, the hearing aid algorithm parameters are updated in an iteration mode according to evaluation indexes, and interaction with the knowledge base is conducted; test sounds are generated for the current patient according to the updated hearing aid algorithm parameters until the current patient feels satisfied. The knowledge base is introduced into the hearing aid self-fitting method, the matching range of the hearing aid algorithm parameters is greatly narrowed, and the fitting efficiency of a hearing aid is obviously improved. The expected value of the hearing aid of the current patient is met to the maximum degree due to the fact that the hearing aid algorithm parameters are updated in the iteration mode according to the evaluation indexes, and the accuracy of the hearing aid algorithm parameters is improved.

Description

technical field [0001] The invention relates to a method for processing audio signals, in particular to a method for self-fitting of hearing aids. Background technique [0002] Hearing loss will seriously affect the physical and mental health of hearing-impaired patients. Wearing hearing aids is currently the most effective means for hearing-impaired patients to improve their hearing. In China, the huge elderly hearing-impaired population, backward hearing aid technology, and the differences between Chinese and English all make the research on Chinese digital hearing aid technology face severe challenges. [0003] Traditional hearing aid fitting mainly relies on the audiologist's interpretation of the patient's problem, which is then translated into the correct electro-acoustic characteristics of the hearing aid. Since the types of hearing aids and the number of signal processing parameters are constantly increasing, the skill requirements of hearing experts are getting hig...
