Abstract: A method and system for personalized acoustic brain wave stimulation of a person. The system comprises an acoustic stimulation device and a remote server. The device comprises a memory able to store operating parameters, acquisition element of a measured signal analysis element in order to assess whether the person is in a state susceptible to stimulation and emission element designed for emitting an acoustic signal. The acquisition element, analysis element and/or emission element operate depending on operating parameters. The device and the remote server comprise means of data transmission for transmitting operating data from the device to the server and transmitting second operating parameters from the server to the device. The remote server comprises means of processing operating data for determining second operating parameters.
