Final answer:
A conductive hearing loss occurs when there is a problem in delivering sound energy to the cochlea, while a sensorineural hearing loss is caused by factors such as aging and head trauma. Both types of hearing loss can be fitted binaurally using hearing aids. Mixed hearing loss, which is a combination of conductive and sensorineural hearing loss, can also be fitted binaurally using hearing aids.
Step-by-step explanation:
A conductive hearing loss occurs when there is a problem in delivering sound energy to the cochlea, such as a blockage in the ear canal or a hole in the tympanic membrane. Hearing aids can be fitted binaurally for conductive hearing loss by pressing against the bone behind the ear to send sound vibrations through the skull.
A sensorineural hearing loss is the most common form of hearing loss and is caused by factors such as aging, head trauma, infections, medications, and environmental effects. Damage to the nerves in the cochlea is not repairable, but hearing aids can partially compensate by amplifying sound.
A mixed hearing loss is a combination of conductive and sensorineural hearing loss. Hearing aids can be fitted binaurally for mixed hearing loss as well.
Therefore, the correct answer is D. all of the above.
