Audiology-Assessment, Hannah Nguyen, 01/19/14

Front 1

Audiogram

Back 1

a graphic representation of the threshold of hearing across the frequency range
x-axis: frequency/pitch (Hz)
y-axis: intensity/loudness (dB)

Front 2

Pure Tone Audiometry

Back 2

pure tones signals are presented to the client one ear at a time where the client responds to those signals that are barely audible

Front 3

Air conduction thresholds

Back 3

the pure tone signals are delivered to the client's ear through the use of headphones, inserts or speakers

Front 4

Bone conduction thresholds

Back 4

the pure tone signals are delivered to the ear using a bone oscillator (vibrator) just to test the cochlea’s sensitivity alone

Front 5

Type of hearing loss

Back 5

Bilateral - both ears
Unilateral - only one ear

Front 6

Peripheral hearing loss

Back 6

Conductive, Sensorineural, or Mixed

Front 7

Retrocochlear pathology

Back 7

Neural pathway (VIII nerve), past the cochlea, going up the brainstem to the auditory cortex

Front 8

Non-organic or functional hearing loss (malingering)

Back 8

faking/exaggeration of hearing loss

Front 9

Air and Bone conduction thresholds

Back 9

Air conduction and bone conduction thresholds are within 10 dB HL of each other. There is a pattern or configuration, usually showing hearing loss increasing or getting worse at the higher frequencies.

Front 10

Mixed hearing loss

Back 10

both conductive and sensorineural hearing loss

Front 11

Conductive hearing loss

Back 11

the problem is in the outer and/or the middle ear

Front 12

Sensorineural

Back 12

the problem is in the cochlea

Front 13

Signature of Noise induced type hearing loss

Back 13

there is a significant decrease at 4000 Hz (notch) and surrounding frequencies, usually bilateral, but not always symmetrical

Front 14

Speech Awareness Threshold (SAT)

Back 14

the threshold of detected speech, typically 10 dB lower than the ST and pure tone average.

Front 15

Spondee Threshold (Speech Reception Threshold or SRT)

Back 15

the threshold of recognition of familiar, two-syllable words with equal stress on each syllable, examples: hotdog, cowboy, pancake, etc.

Front 16

Word Recognition test (Speech Discrimination)

Back 16

suprathreshold test given at different intensity levels (MCL, SL, UCL); presented at one level of loudness when presenting a list of 25 or 50 words.

Front 17

Threshold

Back 17

measures the lowest level of sound in which a person can hear either pure tones in the range important to understand speech and language

Front 18

Superthreshold

Back 18

determine how well a person understands what is heard

Front 19

Stenger Test

Back 19

Using the concept of interaural attentuation and masking thresholds, if a tone is much louder in one ear than the other, you perceive it in just one ear

Front 20

Falconer Lipreading Test

Back 20

above chance performance on a “difficult to lipread” task means that the person did hear the speech.

Front 21

Tympanometry

Back 21

measurement of middle ear mobility as pressure is varied from +200 daPa (x axis) to -400 daPa (y axis) in the external ear canal

Front 22

Type A tympanogram

Back 22

a normal middle ear pressure and compliance

Front 23

Type As tympanogram

Back 23

stiff/shallow eardrum mobility, often seen in otosclerosis

Front 24

Type Ad tympanogram

Back 24

discontinuity/deep abnormal height of the curve, a break in the ossicular chain (disarticulation of the ossicles, possibly due to head trauma).

Front 25

Type B tympanogram

Back 25

Flat with no peak. 3 possible conditions:
Increased mass (no eardrum movement) Abnormally small canal volume (outer ear obstruction/impacted cerumen)
Abnormally large canal volume (perforation of eardrum or pressure equalizing tube placement)
