Customized intelligent cochlear sound processing system and method

Abstract

The invention discloses a customized intelligent cochlear sound processing system and method. An intelligent control module is connected with a sound processing module, a sound precise optimization module, a front microphone audio collection module and a rear microphone audio collection module repectively, the sound processing module is also connected with the sound precise optimization module, the front microphone audio collection module and the rear microphone audio collection module are also connected with the sound processing module, and the intelligent control module monitors and recognizes the ambient sound, and adjusts the parameter configuration of the sound processing module in real time according to the recognition result; the sound processing module performs treatment includingnoise reduction and voice enhancement on the sound signal; the sound precise optimization module provides precise personalized processing and optimization, and can generate a self-defined sound processing strategy; and the front microphone audio collection module and the rear microphone audio collection module are respectively arranged on the front side and the rear side of the intelligent cochlear body external unit and are used for acquiring external sound.

Description

technical field [0001] The invention belongs to the field of signal processing, in particular to a sound processing system and method with a self-defined intelligent cochlea. Background technique [0002] Cochlear implants are currently the only medical devices on the market that can effectively restore hearing to people with severe or profound deafness. The working principle of a general cochlear implant is to convert the sound signal collected by the microphone into a stimulus code and send it to the implant through the signal processing unit. restore hearing. There is often a lot of noise in the environment, which will seriously affect the listening experience of users of auxiliary listening devices. A common practice is to use noise reduction or speech enhancement means to process the sound. However, it is difficult for a single sound processing algorithm or a single parameter configuration of a certain processing algorithm to cope with complex and changeable sound en...

Problems solved by technology

However, for devices such as cochlear implants, each patient's situation is different, specifically, the condition of the residual auditory nerve in each patient's cochlea is different; at the same time, the position of the implant electrode inserted into the cochlea and the distribution of the electrodes cannot be completely consistent. Therefore, the actual situation is that although a general method plus a general configuration can work on a large number of user samples and improve the speech recognition ability of such users to varying degrees, it is not optimal for a single user, and even a small number of users play a negative role

Secondly, the general best solution selected by the system may not be adopted by users, and some users even refuse to accept the solution recommended by the system and insist on their own choice, thus greatly reducing the revenue of the system
