Which type of hearing loss occurs due to problems in sound transmission through the outer ear?

Conductive hearing loss occurs specifically due to issues in the outer or middle ear that hinder the efficient transmission of sound waves to the inner ear. This type of hearing loss can result from various factors, including earwax buildup, fluid in the middle ear, perforated eardrums, or structural abnormalities that impede sound conduction.

In contrast, sensorineural hearing loss is associated with damage to the inner ear or auditory nerve, affecting the ability to process sounds rather than their transmission. Mixed hearing loss combines both conductive and sensorineural elements, indicating issues in both sound conduction and processing. Central hearing loss refers to problems in the brain's ability to interpret sound signals despite normal transmission. Thus, the focus on transmission issues through the outer ear clearly identifies conductive hearing loss as the correct answer.
