What type of vent is suggested for a moderately-severe hearing loss?

For moderately-severe hearing loss, a medium vent is recommended because it strikes a balance between allowing some natural sound and enhancing the effectiveness of the hearing aid. A medium vent accommodates the need for sound to enter the ear canal while minimizing feedback and maximizing amplification for the user's specific loss.

Larger vents may allow too much ambient sound, which can be counterproductive for someone with more pronounced hearing difficulties, as it can dilute the amplification intended for the sounds they struggle to hear. Conversely, a small vent may restrict airflow and lead to an occlusion effect, causing discomfort and an unnatural sound experience. Not employing any vent at all could also result in an overly closed system, which could further exacerbate issues with sound quality and comfort. Therefore, the use of a medium vent effectively manages these aspects for individuals with moderately-severe hearing loss.
