The invention relates to a method and system for personalized acoustic stimulation of the brain waves of a person. The system comprises an acoustic stimulation device (1) and a remote server (100). The device (1) comprises: a memory (6) storing operation parameters, a means (3) for acquiring a measurement signal (S), an analysis means (5) for assessing if the person is fit for stimulation, and anemission means (4) for emitting a sound signal. The acquisition means (3), the analysis means (5), and/or the emission means (4) operate on the basis of the operation parameters. The device (1) and the remote server (100) comprise data transmission means (7, 110) for transmitting data for operation of the device to the server and transmitting second operation parameters from the server to the device. The remote server (100) comprises a means (120) for processing operation data in order to determine the second operation parameters.
