Question

what does the middle ear do?

Answer 1

the middle ear movement is converted into pressure waves in the cochlea fluid.

Answer 2

in the cochlea

Answer 3

They are called stereocilia, which move with the vibrations of the cochlear fluid and the basilar membrane. This movement triggers a signal that travels through the hair cell, into the auditory nerve.

Answer 4

some are sensitive to low frequency sound waves, some to high frequency.

Answer 5

third most common disease

Answer 6

cerumen, produced from sebum, sweat and dead skin, produce in outer ear.

Answer 7

defense for infection, microbes.

Answer 8

in most cases no.. this is due to the risk of pushing it back into the canal where it naturally does it itself. there are some exceptions to the rule.

Answer 9

avoid using earplugs excessively. use a damp cloth to wipe around the outer ear. go to professional and use eardrops

Answer 10

Cochlear implants provide direct electrical stimulation to the inner ear of hearing, or the cochlea , and to the neural system of hearing. They are used for individuals who do not obtain sufficient benefit from hearing aid amplification, usually those with severe-to-profound hearing loss . Prior to implant surgery, the audiologist carries out audiologic testing to determine patient candidacy and provides counseling to the candidate and family members about appropriateness of implantation and viability of other amplification options.

Answer 11

within the inner ear, it is linked to balance and motion.

Answer 12

Prevention research education

Answer 13

cast made of the ear and ear canal for creating a customized earplug or hearing aid

Answer 14

is an instrument used to visually examine the ear canal and eardrum

Answer 15

measures eye movements to assess vestibular (balance) function.

Answer 16

n is an electrophysiologic response to sound that represent the neural function of auditory brainstem pathways. Commonly done with infants who cannot follow instructions.

Answer 17

specialty that deals with the nervous system.

Answer 18

auditory and vestibular nerves

Answer 19

evaluate the hearing of patients who have complaints such as hearing impairment, ear disease, ear pain, and dizziness

Answer 20

The relationship between audiology and otology is perhaps best defined by considering the route that patients might take if they have hearing problems. If a patient has a complaint of hearing impairment, that patient is likely to seek guidance from a general medical practitioner, who is likely to refer the patient to either an audiologist or an otologist or neurotologist. If the general practitioner does not detect any ear disease, the patient is likely to be referred to the audiologist, who will evaluate the hearing of the patient in an effort to determine the need for treatment. The audiologist’s first question is whether or not the hearing loss is of a nature that might be treatable medically. If any suspicion of ear disease is detected, the audiologist will recommend to the general practitioner that the patient receive an otologic consultation to rule out a treatable condition. If the general practitioner detects the presence of ear disease at the initial consult, the patient is likely to be referred first to the otologist, who will diagnose the problem and implement treatment as necessary

Answer 21

5% to 10% of individuals with hearing impairment have treatable medical conditions.

Answer 22

graph of thresholds of hearing sensitivity as a function of frequency.

Answer 23

refers to the decibel level of a sound referenced to audiometric zero

Answer 24

the number of cycles occurring in 1 s, expressed in hertz (Hz).
