Hearing and Audiology

What are the three main parts of the ear?

• upper ear, lower ear, middle ear

• outer ear, middle ear, inner ear

• left ear, right ear, center ear

• front ear, back ear, side ear

What is the most common cause of hearing loss?

• Exposure to loud noises

• Eating too much sugar

• Genetics

• Using a computer for long hours

How is an audiogram used to assess hearing?

• An audiogram is used to assess hearing by measuring blood pressure levels

• An audiogram is used to assess hearing by analyzing taste sensitivity

• An audiogram is used to assess hearing by evaluating lung capacity

• An audiogram is used to assess hearing by measuring the thresholds of hearing sensitivity for each ear across the frequency range.

What frequencies are typically tested in an audiogram?

• 250 Hz to 8000 Hz

• 20 Hz to 20000 Hz

• 500 Hz to 10000 Hz

• 100 Hz to 5000 Hz

What is the purpose of a cochlear implant?

• To increase muscle strength

• To provide a sense of sound to individuals with severe hearing loss or deafness.

• To improve eyesight

• To enhance taste buds

Which part of the ear does a cochlear implant stimulate?

• cochlea

• auditory nerve

• earlobe

• eardrum

What type of hearing loss can be treated with a cochlear implant?

• Sensorineural

• Central

• Mixed

• Conductive

What is the difference between conductive and sensorineural hearing loss?

• Conductive hearing loss is caused by damage to the inner ear or auditory nerve.

• Sensorineural hearing loss is due to problems in the outer or middle ear.

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

• Conductive hearing loss is due to problems in the outer or middle ear, while sensorineural hearing loss is caused by damage to the inner ear or auditory nerve.

What is the role of the cochlea in hearing?

• Convert sound vibrations into electrical signals

• Transmits signals to the brain

• Helps with balance

• Filters out background noise

What is the function of the auditory nerve?

• Transmit sound information from the cochlea to the brainstem

• Control muscle movement

• Regulate body temperature

• Detect light intensity
