What is a common cause of conductive hearing loss?

• A. Inner ear damage
• B. Earwax blockage
• C. Age-related degeneration
• D. Auditory nerve damage

Answer: (B)

Conductive hearing loss occurs when sound transmission through the outer ear or middle ear is impeded. This type of hearing loss can arise from various factors that obstruct the pathway through which sound travels. The presence of earwax blockage is a frequent cause of conductive hearing loss. When earwax accumulates, it can obstruct the ear canal, preventing sound waves from effectively reaching the eardrum. This blockage can lead to a noticeable decrease in hearing ability because the sound is unable to pass through the air-filled outer ear to the eardrum and the ossicles in the middle ear. Other mentioned options relate to different causes of hearing loss. Inner ear damage typically results in sensorineural hearing loss, which is due to issues with sensory receptors or the auditory nerve itself. Age-related degeneration often leads to gradual sensorineural hearing loss as well. Similarly, auditory nerve damage affects the way sound signals are transmitted to the brain rather than interfering with their passage through the ear structures, which would not classify as conductive hearing loss.
