An audiogram can show if you have hearing loss, what type of hearing loss you might have, and it can help identify an appropriate hearing solution. Normal bone conduction thresholds indicate that this 30dB air-bone gap is a case of mild-to-moderate conductive hearing loss. ADHEAR would be an effective non-surgical solution for temporary conductive hearing loss, or chronic conditions such as damaged ossicles, chronic otitis media, or other causes of conductive hearing loss.
