Abstract
An audio system includes a plurality of transducers, one or more acoustic sensors, and a controller. The plurality of transducers transmits an ultrasonic beam towards an ear of a user. The one or more acoustic sensors detect a reflected signal generated by an interaction of the ultrasonic beam with the ear. The controller updates a three-dimensional geometry of the ear based on the reflected signal. The controller determines a head-related transfer function (HRTF) for the user based in part on the three-dimensional geometry of the ear.
