MRC Institute of Hearing Research– Digital Aids & Compliant Ear Tips
This two-year study from the U.K. addresses the success of alternative approaches to providing patients with universal hearing aid(s) at their initial appointment, eliminating the need for ear impressions and subsequent manufacturing of custom made earmolds/shells. Results with both BTE and ITE hearing aids are reviewed.

Chemistry & Rheology of Otoplastic Materials
Ear canal activity and non-compliant materials are the key problems to achieving trouble-free physical fit of earmolds. This research discusses the knowledge of earmold materials and ear impression compounds in providing solutions to hearing impaired people who use behind the ear (BTE) hearing aids

Ear Canal Anatomy & Activity
This article reviews the anatomy of the ear and ear canal activity and their collective impact on the physical fit of earmolds. The need is clearly established to have earmold and shell materials that are compliant and continually compensate for the changing shape and volume of the ear canal.

Smith Study of Comply™ Snap Tips
This study establishes the use of Comply™ Snap Tips beyond demonstrating and temporarily fitting hearing aid technology. The research summarizes participant ratings of comfort, feedback management and cosmetic appeal of Snap Tips, and shows that the audiologist has a new device to couple behind the ear (BTE) hearing aids.
