Verified step by step guidance

Understand the types of hearing loss: Conduction deafness occurs when there is a problem conducting sound waves anywhere along the route through the outer ear, tympanic membrane, or middle ear.

Identify the structures involved in conduction: The outer ear, ear canal, tympanic membrane (eardrum), and ossicles (small bones in the middle ear) are involved in conducting sound to the inner ear.

Consider the possible causes: Conduction deafness can be caused by any obstruction or damage in the outer or middle ear that prevents sound from reaching the inner ear.

Evaluate the options: Blockage of the ear canal by earwax is a common cause of conduction deafness as it physically obstructs the passage of sound waves.

Differentiate from other types of hearing loss: Damage to the cochlea or auditory nerve, and exposure to loud noises typically result in sensorineural hearing loss, not conduction deafness.
