1. An adaptive system for altering a user's motional response to sound, the system comprising: a current source; a sound source including at least one set of sounds; an information source including information associated with at least one characteristic of the at least one set of sounds; a sound device configured with a sound producing structure and in communication with the sound source; a feedback sensor device configured to detect motions associated with a user; a control program configure to receive data representative of the detected motions and to receive the information, the control program having a control algorithm configured to generate control data based on the data representative of the detected motions and the information; a controller configured to run the control program and output control signals based on the control data; an adaptive system configured to adjust parameters of at least one of the controller, the feedback sensor device, the sound source, the information, or the control algorithm; and a vestibular stimulation device configured to deliver a current from the current source to the vestibular system of the user in response to the output control signals.
