For a patient with normal hearing up to 1500 Hz and a bilateral sharply sloping high-frequency loss, what amplification system is most appropriate?

For a patient with normal hearing up to 1500 Hz and a bilateral sharply sloping high-frequency loss, what amplification system is most appropriate?

• A. Binaural completely-in-the-canal hearing aids
• B. Receiver-in-the-ear (RITE) aids with an open ear fitting
• C. Binaural behind-the-ear aids with occluding earmolds
• D. In-the-ear aids with no venting

Answer: (B)

When a patient has normal or near-normal low-frequency hearing but a sharp high-frequency loss, the goal is to provide high-frequency amplification while keeping the ear canal as open as possible to preserve natural low-frequency sounds. An open-ear approach with a receiver-in-the-ear device fits this need well: the behind-the-ear processor drives a receiver placed in the ear canal, and a vented or open dome design minimizes occlusion. This preserves the natural low-frequency audition, reduces the “plugged” sensation, and lowers the chance of muffled speech while still delivering strong gain where the high frequencies are lost. It also tends to reduce feedback and offers a comfortable, cosmetically appealing option. In contrast, fully in-the-canal options or behind-the-ear devices with occluding earmolds would block the ear canal and create more occlusion, dulling low-frequency sounds and potentially causing a muffled or unnatural listening experience for someone with good low-frequency hearing. In-the-ear devices with no venting would have a similar occlusion effect, making them less suitable for this listening profile.
