Test One Flashcards
What are the duties of an audiologist
They facilitate prevention through the fitting of hearing protective devices education programs were in the street in the public hearing screening conservation programs and research
What is the degree of an audiologist
A.u.D
Graphic representation of an audiometric finding showing hearing directionals as a function of frequency
Audiogram
Device for determining the thresholds of hearing
Audiometer
What frequency do we test
250-8,000
What is the intensity we test
0-110
What frequency does the ear hear
20-20,000
What is the symbols for the right ear
Red
X
What is the symbols and color for left ear
O
Blue

What are the four types of tuning forks
Schwa Bach
Rinne
Bing
Webber
What is the schwa Bach
Tuning fork on the table then on patients here let Dr. know when they can hear it but up to the doctors here and they can hear they have conductive hearing loss
What is the rinne test
Conductive tuning fork on table then to mastoid then beside ear bone to air behind ear louder beside ear conductive hearing loss
What is the bing test
Tuning fork behind ear close ear canal louder or softer
Sensory neural hearing loss
What is the webber test
Localization tuning fork middle of forehead
Normal both sides
Louder in one side sensory neural
What is the parts of the outter ear
Pinna
External auditory meadus ( ear canal)
What is the parts of the middle ear
Tympanic membrane Malleus Incus Stapes Eustation tube
What are the parts of the inner ear
Oval window
Cochlea
What is the energy in the ear
Acoustic
Mechanical
Hydraulic
Chemical
What energy is the outside ear
Acoustic
What energy hits the ossicles
Mechanical
What energy moves the fluid
Hydraulic
What energy does the cochlea pick up the sound nerve to brain
Chemical
What is air conduction
Ability to be able to hear any given some through the normal hearing pathway
What is bone conduction
Bypassing little going directly to enter year to get response of cochlea also to see if they have conductive hearing loss
What are the types of hearing loss
Sensorineural
conductive
non-organic
mixed
What is when sound molecules pushed together
Compression
What happens when the molecules spread apart
Rare fraction
What is amplitude
The extent of the vibratory movement of mass from its position of rest that point farthest from the position of rest
What is the longitudinal wave
Cycles occur parallel can be same or opposite
Complex
What is a sine wave
Smooth wave that repeats cycles pure tones and tones that are only one pitch
What is frequency
The number of complete ossicles of a vibrating body per unit of time.
What is intensity
The amount of sound energy per unit of area
What is the lowest sound you can hear
Fundamental frequency
What is harmonics
While number multiples of fundamental frequency
What is formance frequency
Concentration of acoustic energy around particular frequency in speech wave
What the pressure goes up what happens to the loudness
It goes up
What is the first step in seeing a patient
Case history
What are s the threshold
Softest level which a patient can hear 50% of the time
What is localization
Figuring out where the sound is coming from
What are the three types of head phones
Insert ear
Supra aural
Bone ossilator
When you can hear what does the audiologist do
Turn down by 10 dB
When you cant hear what does the audiologist do
Turn up 5db
What is the air bone gap
The amount by which the air conduction threshold of a patient exceeds the bone conduction thresh hold at any frequency in the same ear
What happens when the normal ears and those with sensory neural impairments are covered by earphones or occluded by other devices, there is an increase in the intensity of a sounds delivered by a bone conduction vibrator to the cochlea. Changes in osseotympanic bone conduction.
Occlusion effect
What bone is the ossilator
Mastoid
How do you find the pure tone average
Results from 500 1000 and 2000 add up and divide by 3
What is a pure tone
One single simple tone
What is speech
Complex
What are the degrees of hearing loss
Normal 0-20 Mild 21-40 Moderate 41- 55 Moderately severe 56-70 Severe 71-90 Profound 91 and above
What is an audiologist
Engaged autonomous practice to promote healthy hearing communication competency and quality of life for persons of all ages
