Wearable sound feedback system based on brain electrophysiological signals

Abstract

The invention provides a wearable sound feedback system based on brain electrophysiological signals. By virtue of the system which is worn on the head of an individual, the brain electrophysiologicalsignals of the individual are collected and extracted; then, on the basis of the characteristics of the brain electrophysiological signals, specific sound signals are generated in real time; and the sound signals are fed back to an auditory system of the individual in real time, so that real-time sound feedback based on the characteristics of the brain electrophysiological signals of the individual is achieved. According to the system, personalized sound feedback for the same individual is achieved, and meanwhile, real-time sound feedback is achieved.

Description

technical field [0001] The invention relates to the technical field of EEG neural biofeedback, in particular to a wearable sound feedback system based on EEG physiological signals. Background technique [0002] Electroencephalogram (EEG) is a weak electrical signal produced by the brain. EEG can be recorded by electrodes worn on the head. It characterizes the bioelectric activity of brain cell populations and is an important tool for studying the brain's advanced cognitive functions. EEG-based neurobiofeedback (Neurobiofeedback, NFB) is to convert EEG signals into auditory information or visual information and play them to the subjects. In the process of neurobiological feedback, the subjects can selectively enhance or inhibit certain components through training, so as to achieve the purpose of regulating brain function. The technique was first developed from Pavlov's theory of classical conditioning, which was perfected by psychologist Skinner. At present, neurobifeedbac...

Problems solved by technology

[0003] Based on the above theory, there is a brain electrical stimulator in the prior art, and the brain electrical stimulator plays the corresponding brain electrical stimulation (such as sound) according to the preset brain electrical stimulation process. The preset brain electrical stimulation process here is It is obtained according to the extracted brain electrophysiological signals of a certain number of individuals, so the brain electrical stimulation played is not targeted, cannot meet the individual needs of personnel, and the obtained treatment or health care effect is not good.

In addition, the existing brain electrical stimulators rely on ordinary computers (such as: desktops, notebooks), which are bulky and inconvenient to carry.
