Embodiment Construction
[0048] Such as figure 1 As shown, it is a schematic diagram of the equipment structure of the present invention, including earphones, EEG signal acquisition devices, IC circuits, signal transmission devices and terminal equipment, and the EEG signal acquisition devices include EEG signal acquisition electrodes and EEG signal reference electrodes. The acquisition device samples and quantifies the analog brain waves generated by human brain activities, and turns them into discrete digital signals for subsequent processing; the two electrodes are integrated with the earphones, in order to collect EEG signals more accurately, The electrodes are located on the head, and the EEG signal reference electrode clips are located on the ears.
[0049] The IC circuit includes a signal amplifier and a signal processor. The signal amplifier is a pre-amplifier, which amplifies the quantized digital signal and enhances the anti-interference ability in the process of processing and transmission;...

The invention relates to equipment and a method for tinnitus treatment based on an electroencephalogram frequency-domain characteristic indexation algorithm. The equipment comprises a headset, an electroencephalogram signal acquisition device, an IC (integrated circuit) circuit, a signal transmitting device and a terminal device. The electroencephalogram signal acquisition device is used for sampling and quantifying simulated brain waves generated by human brain activities and converting the brain waves into discrete digital signals before subsequent processing. The IC circuit is used for amplifying the quantified digital signals to improve antijamming capability during processing and transmitting. A signal processor is used for denoising preprocessing of acquired signals to improve intensity of brain wave signals. The signal transmitting device is connected with the IC circuit and the terminal device to transmit parameters extracted by the IC circuit to the terminal device. A PC (personal computer) serves as the terminal device to process the parameters, display and feed back. By the aid of the equipment and the method for tinnitus treatment based on the electroencephalogram frequency-domain characteristic indexation algorithm, treatment effects can be objectively judged according to electroencephalograms of patients, and high accuracy, avoidance of subjective judgment of patients and applicability to both hospitals and families are realized.
Description
[0001] technical field [0002] The invention relates to a tinnitus treatment device and method based on an EEG frequency domain characteristic index algorithm. [0003] Background technique [0004] Tinnitus is a common and frequently-occurring disease in clinical practice, and its etiology has not been clearly concluded at present. Usually, the sound masking treatment is used, that is, to select different frequencies of sound to the patient, let him feel whether the sound can make him feel that the tinnitus can be relieved or disappeared, and then continue to listen to the sound to the patient, which has reached the goal of treatment or relief. Purpose. This method of self-perception by the patient is not objective and has poor accuracy. [0005] Contents of the invention [0006] The object of the present invention is to provide a tinnitus treatment device based on an EEG frequency-domain characteristic index algorithm to objectively judge and evaluate the tinnitus...
