Which is NOT a true statement regarding conductive and sensorineural hearing losses?

• A. Conductive hearing losses are often reversible
• B. Sensorineural hearing losses are usually permanent
• C. Sensorineural hearing losses impair discrimination
• D. Conductive loss does not affect threshold level

Answer: (D)

Conductive hearing loss involves problems in the outer or middle ear that prevent sound from being conducted to the inner ear. This type of hearing loss can be caused by factors such as ear infections, fluid in the ear, earwax buildup, or structural abnormalities. One of the key characteristics of conductive hearing loss is that it often affects the thresholds of hearing, meaning it can indeed raise the level at which sounds can be heard. Therefore, the statement that "conductive loss does not affect threshold level" is not accurate, making it the correct choice to identify as not true. The other statements accurately reflect established knowledge regarding hearing loss types. Conductive hearing losses can sometimes be reversed with medical treatment or surgical intervention, making that statement valid. Sensorineural hearing losses, caused by damage to the inner ear or auditory nerve, are typically permanent, and this is why the assertion about their permanence is true. Furthermore, sensorineural hearing loss can impair not only sound detection but also the discrimination of speech and other complex sounds, which aligns with the truth of that statement.
