There are three major types of vents found in a hearing aid shell or earmold: parallel, diagonal, and trench. CANAL-LOK. Kuk F. Maximum user real-ear insertion gain with ten earmold designs. It is used for a rising audiogram configuration to control high frequency output. PLEASE NOTE: Due to inherent differences between actual materials and computer monitor displays, it is likely that some colors may vary slightly from products shown here. For an acoustic horn to work effectively, a gradual increase in internal diameter over a specific length is required. This is the reason that it is chosen for aesthetical reasons. A medium or large vent can be ordered, but because you cannot predict what will be said about occlusion, an SAV is preferred. This is used only when there is insufficient physical space for a parallel vent (when the ear canal is too short or too small of a diameter). Increases in bore diameter alone, however, yield little or no change in the high frequency response. 5 Prrton verification that you are using the proper size and type. They fit flush with my ear and are so comfortable, Tarra Stanley, whos worn hearing aids since her 20s, told. The Patriot earpieces are hollow in the canal area and made of extremely soft silicone material, providing excellent comfort. In BTEs, tubing 35-45mm in length connects the earhook (tonehook) through the earmold to the medial end of the earmold. If it is high in the tone hook will have the least amount of effect; and a dampener in the tubing (midway through the earmold sound bore) will have maximum effect. There are 6 different plug sizes with various diameter vent holes. F2C is also available in a choice of nine translucent color tints.
