It is easy to forget that the vent type can have a significant effect on the reduction in low frequency energy, as diagonal vents reduce low frequency energy more than parallel vents with the same internal diameter. It is difficult to modify and tubing is secured using a CFA tube and seating ring. The hearing aid was programmed for a flat 50 dBHL hearing loss and the prescribed target gain is shown in red.

What frequency range do dampers affect and where is the placement of a damper? Explain why an open fitting can be a good thing. The semi-skeleton option is an excellent selection when the ear is not undercut in the upper concha and full retention can be obtained in the helix and anti-tragus. Sound leaking out of the ear will be picked up by the mic, causing acoustic feedback. 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). Keeping the patient's preference and hearing loss severity in mind, you can selectthe least visible style(i.e., canal-lok, skeleton, concha).
