All-digital type hearing-aid and changing channel matching and compensating method thereof

Abstract

The invention discloses an all-digital type hearing-aid and a changing channel matching and compensating method of the all-digital type hearing-aid. The changing channel matching and compensating method of the all-digital type hearing-aid comprises the following steps: a microphone receives sound and transmits the sound to a analog-digital converter; an analog-digital converting device converts a sound signal into a digital signal; the digital signal is transmitted into a processor of a digital signal processor (DSP), so that the all-digital type hearing-aid and changing channel matching and compensating method realizes the changing channel matching and compensating hearing gain, and further realizes compensation, noise elimination, and squeal elimination process of a voice signal of the sound and judges and classifies the voice signal; the signal output by the digital signal processor enters into the analog-digital converting device to output a simulation signal; and a telephone receiver outputs sound to patients. On the prerequisites of not losing language recognition rate of the patients, the all-digital type hearing-aid and the changing channel matching and compensating method of the all-digital type hearing-aid have the advantages of reducing the number of channels, lowering power consumption of the signal processor, being high in matching degree, and accurate in fitting. Meanwhile, the all-digital type hearing-aid and the changing channel matching and compensating method of the all-digital type hearing-aid further achieve compensation for the voice signal, noise elimination, and squeal elimination process of a voice signal of the sound and judge and classify the voice signal, further achieve the function of invoking different control parameters specific to different surroundings, thereby further having the advantages of being effective and comfortable.

Description

technical field [0001] The invention relates to an all-digital hearing aid and a channel-changing matching compensation method thereof. Background technique [0002] With the development of the economic level, people pay more and more attention to the quality of life and interpersonal communication. However, according to statistics, the number of hearing-impaired patients in my country is about 26 million, which has brought a huge burden to society and families. Most hearing-impaired patients can return to rehabilitation by wearing hearing aids or language training. However, hearing aids require accurate fitting and repeated adjustments. Patients are uncomfortable to wear, have loud noises, and unnatural sound quality, requiring long-term adaptation. Experts in the field of audiology and the medical community have been working to change this. The introduction of chip and software technology makes the functions of hearing aids more and more high-end and humanized. Such as...

Problems solved by technology

While increasing the technical cost, the real needs of patients are ignored. At the same time, due to the increase in the number of channels, the amount of calculation increases, which increases the power consumption of the system.
