What is the main difference between conductive and sensorineural hearing loss?

• Conductive hearing loss is due to nerve damage, while sensorineural is due to blockages.

• Conductive hearing loss affects the outer or middle ear, while sensorineural affects the inner ear or auditory nerve.

• Conductive hearing loss is permanent, while sensorineural is temporary.

• Conductive hearing loss is genetic, while sensorineural is caused by infections.
