Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] The invention provides a tinnitus hearing aid, which includes three parts: structure, function customization and signal processing algorithm. The block diagram of the signal processing system of the tinnitus hearing aid of the present invention, as figure 1 shown. The invention provides three functions of tinnitus masking, hearing compensation and tinnitus masking combined with hearing compensation, including two functional modules of tinnitus masking and hearing compensation.

[0033] The tinnitus masking module includes a signal generation and pre-storage unit, a masking signal processing unit, and a masking signal output unit. Under the adjustment of the control module, the module outputs masking signals of suitable type, frequency band and sound pressure level.

[0034] The control module includes: a preset unit, a selection unit...

Abstract

The invention relates to a tinnitus hearing aid which comprises a tinnitus masking module and a hearing compensation module, and is characterized in that the tinnitus hearing aid further comprises a control module; the control module comprises a pre-setting unit, a selecting unit and a voice classification device; the pre-setting unit is used for selecting any one function mode in tinnitus masking, hearing compensation and tinnitus masking and hearing compensation, and inputting related preset parameters; the voice classification device is used for sequentially performing pre-treatment, feature extraction and classification according to received signals, and finally determining a sound field environment; a signal processing algorithm is selected and the parameters in the signal processingalgorithm are adjusted according to the function mode selected by the pre-setting unit and the determined sound field environment, and optimal combination is further performed; and the selecting unitis used for opening the voice classification device and working according to the function mode selected by the pre-setting unit.

Description

technical field [0001] The invention relates to tinnitus treatment equipment, in particular to a tinnitus hearing aid. Background technique [0002] Currently, there are four types of masking devices for treating tinnitus: FM noise, hearing aids, special tinnitus maskers, and tinnitus hearing aids. Among them, the masking sound used for FM noise is poorly controllable and adjustable, and it is difficult to accurately match the patient's tinnitus sound. Hearing aids are suitable for patients with sensorineural deafness, which can improve hearing and make tinnitus disappear, but the effect on tinnitus without hearing loss is not obvious. The special tinnitus masker does not affect conversation and can fully mask tinnitus, but for patients with tinnitus and hearing loss, the short-term effect is not obvious. Since hearing aids and special tinnitus maskers only have a single tinnitus masking or hearing compensation function, they can only meet a small number of pure tinnitus o...
