Hearing Disorders

Question 1

What is a cycle

Answer 1

One complete back and forth vibratory motion

Question 2

what is frequency

Answer 2

how fast the particles vibrate; measure by the number of complete vibratory cycles in a unit of time

Question 3

what is a pure tone

Answer 3

A sound consisting of only 1 frequency

Question 4

How is sound volume measured

Answer 4

Decibels

Question 5

Quite sounds are

Answer 5

Low decibels

Question 6

Loud sounds are

Answer 6

high decibels

Question 7

how is hearing loss categories

Answer 7

type
degree
location
configuration

Question 8

what are the types of hearing loss

Answer 8

conductive
sensorineural
mixed

Question 9

what are the degree hearing loss

Answer 9

serverity

Question 10

what is the location of the hearing loss

Answer 10

perripheral or central auditory system

Question 11

what is the configuration of hearing loss

Answer 11

the extent of hearing loss at various frequencies

Question 12

where does conductive hearing loss originate from

Answer 12

the outer ear

Question 13

where does sensorineural hearing loss originate from

Answer 13

the inner ear

Question 14

where does mix hearing loss originate from

Answer 14

a combination of sensorineural and conductive

Question 15

what is conductive hearing loss

Answer 15

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

Question 16

what is sensorineural hearing loss

Answer 16

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

Question 17

what is mixed hearing loss

Answer 17

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

Question 18

what is included in the assessment of hearing disorders

Answer 18

Audiometry
Pure tone audiomety
Immittance testing
Electrophysiologic testing

Question 19

what is audiometry

Answer 19

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

Question 20

what is pure tone audiometry

Answer 20

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

Question 21

what is an audiometer

Answer 21

the device used to generate the ones for hearing testing

Question 22

what is the threshold?

Answer 22

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

Question 23

what is an Audiogram

Answer 23

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

Question 24

what is Air conduction testing

Answer 24

tests a person hearing as it travels through air

Question 25

What is Bone conduction testing

Answer 25

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

Question 26

What is immittance testing

Answer 26

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

Question 27

what are the two types of immittance testing

Answer 27

Tympanometry Acoustic Reflex

Question 28

what is a non behavioral test

Answer 28

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

Question 29

what is a tympanometry

Answer 29

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

Question 30

what is a tympanometry

Answer 30

the instrument used to graphically quantify the tympanic membrane mobility

Question 31

what is acoustic reflex testing

Answer 31

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

Question 32

What is the electrophysiologic testing

Answer 32

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

Question 33

what are the two most common types of electrophysiologic testing

Answer 33

otoacoustic emissions auditory brainstem response

Question 34

What is atresia

Answer 34

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

Question 35

what is otitis externa

Answer 35

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

Question 36

what is eardrum perforation

Answer 36

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

Question 37

what is Otitis Media

Answer 37

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

Question 38

What is Otitis Media with Effusion

Answer 38

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

Question 39
