During the production process, the material sets and is cured. Dampers smooth the frequency response in the mid-frequency range (1000 to 3000Hz). The first area of concern is canal length. Size of the ear canal will determine hearing aid type as well as earmold acoustic configuration. From custom hearing aids to earpieces for a variety of applications, custom ear impressions are the foundation to a successful fitting. Acoustic dampers (or resistors) remove energy from the frequency response; they decrease the peaks and dips of the freq response. The hardness can vary anywhere from Shore A 25 to Shore A 60. Generally, all power behind the ear hearing aids will be coupled with an occluding earmold to obtain a good seal. e-Compound Additivee-Compound canal additive is designed to reduce feedback by diffusing reflected sound between the tip of the earpiece and the eardrum.
