Abstract: An exemplary system is configured to generate a three-dimensional (3D) scan of an ear of a user, obtain a hearing loss profile of the user, generate, based on the 3D scan of the ear of the user and the hearing loss profile of the user, a virtual representation of a customized hearing device for the user, and provide, for display to the user by way of a display device, a live preview image that includes the virtual representation of the customized hearing device and that demonstrates how the customized hearing device would appear when worn by the user.

Abstract: An exemplary hearing device configured to be worn by a user includes an accelerometer configured to output accelerometer data representative of an acceleration of the hearing device and a processor configured to maintain data representative of a walking detection algorithm, determine an optimized parameter for the user for use with the walking detection algorithm, and apply, in accordance with the optimized parameter, the walking detection algorithm to the accelerometer data to determine a walking state of the user while the user wears the hearing device.
