Q

audiologist and dispensing and balance

A

audiologists evaluate the need for hearing devices and assess, fit, and dispense hearing aids, implantable technology, and other assistive listening devices. Audiologists are also involved in post-fitting treatment and in educational programming and facilitation. Many audiologists also carry out testing designed to quantify balance function and treat balance dysfunction.

Q

How has audiology change?

A

Audiologists can measure, with great precision, the amount of amplification delivered to an eardrum. And they can alter that amplification and other hearing technologies in a number of ways to tailor them to the degree and nature of an individual’s hearing loss and accommodate the personal preferences and desires of most patients.
It is no longer a yes or no question.

Q

What are questions which Audiologist must consider?

A

*Does a hearing loss exist?
* What is the extent of the hearing loss? Is the dysfunction of the auditory system a symptom of an underlying medical disorder? *
* Is the loss causing impairment in communication ability?
* Can the impairment be overcome to some extent with hearing aid amplification, implantable technology, or other hearing assistive technologies?
What are the specific technology needs of the patient?
How can success with this technology be verified?
How much additional treatment is necessary?

Q

What is an audiologist?

A

“Audiologists are professionals engaged in autonomous practice to promote healthy hearing, communication competency, and quality of life for persons of all ages through the prevention, identification, assessment, and rehabilitation of hearing, auditory function, balance, and other related systems.”

Q

Describe how hearing aids work

A
  • microphone converts sound to electricity
  • it amplifiers it.
  • the speaker can convert electricity to sound into the individuals ear.

Q

what is the ear function?

A

convert sound to neural signals

18
Q

what does the ear drum does?

A

the tympanic membrane moves due to sound waves.

19
Q

what is the inner ear?

A

cochlea

20
Q

what is the cochlea made from

A

Saltwater like fluid

21
Q

what does the middle ear do?

A

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

22
Q

where are the hair cells?

A

in the cochlea

22
Q

what do the hair cells do?

A

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.

23
Q

stiffness and flexibility

A

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

24
Q

hearing loss is the……

A

third most common disease

25
Q

what is ear wax name?

A

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

25
Q

what is the purpose for earwax

A

defense for infection, microbes.

26
Q

is removing earwax ideal….

A

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.

26
Q

what to do to remove build up of earwax

A

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

27
Q

cochlea implants

A

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.

27
Q

vestibular system

A

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

28
Q

where may an audiologist work?

A

Prevention
research
education

29
Q

ear impression

A

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

30
Q

otoscope

A

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

31
Q

videonystagmography/
electronystagmography

A

measures eye movements
to assess vestibular
(balance) function.

32
Q

auditory brainstem
response

A

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

32
Q

Neurology

A

specialty that deals with the
nervous system.

33
Q

the VIIIth cranial nerve

A

auditory and
vestibular nerves

34
Q

audiologists

A

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

35
Q

Medical profession or audiologist?

A

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

36
Q

hearing and disease

A

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

37
Q

audiogram

A

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

38
Q

Hearing level (HL)

A

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

39
Q

frequency

A

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