For concha and less-severe hearing loss, the concha area is:

• A. More open concha area
• B. Smaller concha
• C. Same concha area as normal
• D. No concha involvement

Answer: (A)

The main idea is how ear-canal fit and acoustics relate to how severe the hearing loss is. For milder (less-severe) losses, it’s common to use a more open concha area in the ear canal fitting. An open concha reduces the occlusion effect and preserves more of the ear’s natural resonance, which helps maintain sound quality and comfort without needing a tight, fully occluding seal. So the concha area being more open aligns with fitting practices for milder hearing losses—allowing more venting and a less restricted canal. A smaller concha would increase occlusion and isn’t typical for less-severe loss, while staying the same as normal or having no concha involvement wouldn’t reflect the functional adjustment that comes with milder hearing loss.
