Abstract

The application discloses a noise resistance and adaptability measuring method based on beta band time gradient measurement, characterized in that two types of abnormal data sensing test tasks, i.e., a music condition and a noise condition, are set, and the brain electrical signals of the tested personnel in the two types of tasks are collected; the baseline normalized band power average value of the beta band in the time window of 300-400 ms in the Fz channel of the tested personnel under different tasks is calculated; the minimum time gradient serial number between the beta power of the music.abnormal and the noise.abnormal, the music.normal and the noise.normal is calculated respectively; the smaller the minimum time gradient serial number, the stronger the noise resistance; if the minimum time gradient serial number is smaller, the stronger the noise adaptability; if the same tested personnel is represented as noise.normal, the tested personnel is of a normal sensitive type to noise; if the same tested personnel is represented as noise.hyper, the tested personnel is of a hyper sensitive type to noise; and the method has the advantages that the noise resistance and adaptability of the tested personnel are objectively and directly evaluated.
