Kuk F. Maximum user real-ear insertion gain with ten earmold designs. It is when the opening of the vent is a smaller diameter then the end (closer to the TM). The internal diameter of the tubing affects the passage of sound along the tube; tubing wall thickness relates to leakage of sound. A canal-shell (e.g., half-shell) would be our recommended style. Custom earmolds are recommended for their secure fit because they offer significantly better retention over universal domes. This is due to the fact that changes in the high frequency response can only be accomplished mechanically with a horn, and not with a larger sound bore within the earmold. Regardless of the advantages of coupling a custom earmold to a thin tube/wire product, there are several acoustical changes that should be considered when closing off the ear canal. Acrylic earmolds are made of the hardest material, are resistant to breakage and are the The earmold should fit as comfortably as possible without causing irritation to the external ear. Fills the entire concha and is used for body type instruments, auditory trainers, pilot molds, anesthesiologist molds (with an adapt-a-scope adapter), communication molds, some headsets, and earbud molds (with a boot or pressure fit). Name four limitations to non-custom ear-tips (domes). There are two main types of earmold styles: occluding and non-occluding.
