Questions and Answers
A patient reports difficulty hearing after a head injury. An audiologist determines the cochlea is undamaged, but the patient is still diagnosed with hearing loss. Which type of hearing loss is most likely affecting this patient?

Central hearing loss
Describe the primary difference between conduction hearing loss and nerve hearing loss, focusing on the anatomical location of the impairment.
Describe the primary difference between conduction hearing loss and nerve hearing loss, focusing on the anatomical location of the impairment.
Conduction hearing loss involves impairment in the outer or middle ear, preventing sound from reaching the cochlea, whereas nerve hearing loss involves damage to the cochlea or auditory nerve itself.
A child experiences repeated ear infections, leading to fluid buildup in the middle ear. Over time, this causes hearing impairment. What type of hearing loss is likely to develop and why?
A child experiences repeated ear infections, leading to fluid buildup in the middle ear. Over time, this causes hearing impairment. What type of hearing loss is likely to develop and why?
Conduction hearing loss, because the fluid buildup impairs the transmission of sound through the middle ear to the cochlea.
An elderly person experiences gradual hearing loss, and an examination reveals significant damage to the hair cells in the cochlea. Identify the specific type of hearing loss and what factor most likely caused it.

Explain how damage to the auditory nerve can result in a different type of hearing loss compared to damage to the small bones in the middle ear.

Study Notes
- Deafness stems from alterations at any point in the auditory system.
- There are three types of hearing loss: conduction, nerve, and central.
Conduction Hearing Loss
- Conduction hearing loss results from impaired sound transmission.
- The impairment occurs via the external or middle ear.
- Sound is unable to reach the cochlea.
Nerve Hearing Loss
- Nerve hearing loss is caused by the destruction of hair cells.
- Nerve hearing loss is caused by damage to the auditory nerve.
Central Hearing Loss
- Central hearing loss is caused by brain damage.

Description
Hearing loss can be caused by alterations in the auditory system. There are three categories of hearing loss: conduction, nerve, and central. Conduction hearing loss impairs sound transmission. Nerve hearing loss results from damage to hair cells or the auditory nerve. Central hearing loss stems from brain damage.
