15
Q

what is conductive hearing loss

A

reduces the overall sound loudness
disruption in the flow of sound to the inner ear
often permanent can be treated medically and or surgically

16
Q

what is sensorineural hearing loss

A

Damage to the inner ear or the nerve pathways from the inner ear to the brain
Impact sthe loudness and sound clarity
permanet hearing disorder- not able to be fix but can be improved with hearing aids
90% of hearing loss

17
Q

what is mixed hearing loss

A

Not always permanet if conductive loss can be resolved
sometimes starts as a conductive loss that evolves into a sensorineural loss

18
Q

what is included in the assessment of hearing disorders

A

Audiometry
Pure tone audiomety
Immittance testing
Electrophysiologic testing

19
Q

what is audiometry

A

the quantitative measurement of hearing
necessary to determine the type, degree. location and configuration of hearing loss

20
Q

what is pure tone audiometry

A

masures hearing acuity in both ears of sounds Hz frequencies betwen Hz and 8000 HZ

21
Q

what is an audiometer

A

the device used to generate the ones for hearing testing

22
Q

what is the threshold?

A

the lowest dB ( volume) level at which the tone is barely audible

23
Q

what is an Audiogram

A

a graph that plots the frequency threshold for each ear and at each frequency tested
‘O’ left ear
X= right ear

24
Q

what is Air conduction testing

A

tests a person hearing as it travels through air

25
Q

What is Bone conduction testing

A

a vibratory unit ( oscillator) is placed on the skull behind the ear

26
Q

What is immittance testing

A

provides information regarding how mobile the tympanic membrane is and middle ear function.
does not provide specific information regarding hearing acuity.

27
Q

what are the two types of immittance testing

A

Tympanometry
Acoustic Reflex

28
Q

what is a non behavioral test

A

the stimulus is applied and the eardrum either responds appropriately or it doesn’t

29
Q

what is a tympanometry

A

gives information regarding air pressure in the external ear canal compared with movement of the tympanic membrane and ossicular chain in the middle ear

30
Q

what is a tympanometry

A

the instrument used to graphically quantify the tympanic membrane mobility

31
Q

what is acoustic reflex testing

A

an involuntary contraction of the stapedius muscles located in the middle ear

32
Q

What is the electrophysiologic testing

A

Non behavioral test that are often administered to difficult to assess individuals or to determine the side of a specific auditory lesion

33
Q

what are the two most common types of electrophysiologic testing

A

otoacoustic emissions
auditory brainstem response

34
Q

What is atresia

A

hearing loss in the outer ear
an absence of a normal ear canal opening
congenital condition
also known as Treacher Collins syndrome

35
Q

what is otitis externa

A

hearing loss in the outer ear due to infection
swimmers ear
vacteria grows due to frequent moisture exposure in the ear canal
can be treatd with ear drops

36
Q

what is eardrum perforation

A

hearing loss in the middle ear
a hole or rupture of the tympanic membrane
heals on its own(weeks and sometimes months)

37
Q

what is Otitis Media

A

inflammation and infection of the middle ear
associated with the size and positioning of the eustachian tub

38
Q

What is Otitis Media with Effusion

A

Watery/ fluid like substance fills the middle ear
diagnosed with an otoscope

39
Q

what is the APS Assessment

A

ruling out off the presence of hearing loss

40
Q

What are the APD Treatment

A
  1. direct skills remediation
  2. Compensatory strategies
  3. Enviornmental modification
