Developmental tendency of hearing aid semi-auto-manufacturing

Abstract

What's the developmental tendency of the hearing aid manufacturing in the future? The answer is a rapid production or/and CAD/CAM technology. The new technology is quite different from the conventional manufacturing method. This article shows the differences between the 2 types of approach in detail, and analyzes these differences. The authors figure out where and how to cut an ear shell impression that will give help to the hearing aid manufacturing process, and make the CAD/CAM method to fit for the Asians' ears.
