Systems and methods are provided for customizing an auditory prosthesis or other medical device. Customizing the auditory prosthesis includes obtaining and evaluating system data. The system data includes data from multiple sensors, including one or more sensors of an auditory prosthesis and one or more sensors of a recipient computing device. Based on the evaluation of the system data, a target behavior is determined, such as operating the auditory prosthesis in a particular sonic environment or with particular auditory prosthesis settings.

Disclosed examples include technology to use residual vestibular function or residual vestibular nerve function of a recipient to provide low frequency information to enhance auditory percepts caused by auditory prostheses. An example can include adding a low frequency actuator to a cochlear implant for placement close to the vestibule of the ear. In addition or instead, one or more electrodes can be disposed proximate the vestibule of the ear to electrically stimulate residual vestibular function provided by, for example, the utricle and saccule. The stimulation provided by these components can be optimized for delivery to the vestibular system.
