Earmolds are another option. You cannot tell the difference by just looking at it. The 3D model would then be transmitted over the internet to the earmold fabricator. There are three major types of vents found in a hearing aid shell or earmold: parallel, diagonal, and trench. Acoustic dampers (or resistors) remove energy from the frequency response; they decrease the peaks and dips of the freq response. Let's first consider the retention of an earmold. The canal mold is comfortable and cosmetically appealing. When I first started in this field there were two types of earmold materials that were in common usage: Lucite and Polyvinyl chloride, or PVC; Lucite being hard and PVC being soft.
