Abstract:
1. A method comprising: obtaining static data from an ear canal of a subject with a three-dimensional scanner, the static data including a three-dimensional image of a surface of the ear canal at a predetermined pressure; obtaining dynamic data from the ear canal of the subject with a three-dimensional scanner, the dynamic data including data from the ear canal characterizing changes in a shape of the ear canal related to a compliance of the ear canal to changes in pressurization and a shape change of the ear canal in response to a musculoskeletal movement of a head of the subject; providing a three-dimensional model of an earpiece; evaluating a fit of the three-dimensional model of the earpiece to the ear canal with a simulation executing on a processor based on the static data and the dynamic data; and modifying a characteristic of the three-dimensional model to improve the fit based on the evaluation of the fit by the processor.
