Volume control method and device based on brain wave signal and storage medium

The invention discloses a volume control method and device based on brain wave signals and a storage medium, and the method comprises the steps: obtaining a plurality of pieces of brain wave signal data, and determining the change data of the plurality of pieces of brain wave signal data; determining the change amplitude of the brain wave signal data according to the change data; and adjusting and controlling the playing volume of the terminal equipment according to the variation amplitude. According to the method and the device, the brain wave signal data can be analyzed, and the playing volume of the terminal equipment is controlled based on the change of the brain wave signal data, so that the functions of the terminal equipment are controlled more intelligently, manual operation of a user is not needed, and convenience is provided for use of the user.
