SHS UIUC 451 Exam #1 Questions with correct answers
Auditory rehabilitation vs. auditory habilitation - ✔✔-Rehabilitation- restore
(more for adults)
-Habilitation- give to someone who has never had it (more for children)
Be able to calculate pure tone average. What is it? - ✔✔-Take frequencies from
500, 1000, 2000 hz, then add them and divide by three (do for both ears
-the average of hearing threshold levels at a set of specified frequencies
When do PTAs and SRTs agree vs. disagree - ✔✔-Its a way to confirm pure tone
average
-SRT ex: baseball, snowman see how low they can go and still hear
-Within 10 dBs pf PTAs are in agreement and outside of 10 dBs are not in
agreement
ICF what is International Classification of function and what can it be used for? -
✔✔Framework to address functioning and disability related to a health condition
within the context if the individual's activities and participation in everyday life
4 components of AR and examples - ✔✔Sensory management to optimize
auditory function;
Instruction in the use of technology and control of the listening environment;
Perceptual training to improve speech perception and communication; and
Counseling to enhance participation and address emotional and practical
limitations.
, Know what MCL, UCL and dynamic range are and how they are related - ✔✔-
MCL- audible but not uncomfortable
-UCL- max (when it becomes uncomfortably loud for them
-Dynamic range- distance between hearing thresholds and the UCL (patients
usable hearing
-Compression takes sound a squishes them into a patient's dynamic range of
hearing
Gives the least amount of gain to loud level sounds
Gives most amount of gain to soft level coins
Gives
WHat is SNR and how do you figure it out - ✔✔the ratio of the strength of an
electrical or other signal carrying information to that of interference, generally
expressed in decibels.
-If your signal and noise measurements are already in dB form, simply subtract
the noise figure from the main signal: S - N.
-For example: you measure a radio signal with a strength of -5 dB and a noise
signal of -40 dB. -5 - (-40) = 35 dB.
Advantages and disadvantages of different stimuli in speech tests - ✔✔
What are PSAPS? (PERSONAL SOUND AMPLIFICATION DEVICES How do they differ
from Hearing Aids - ✔✔PSAPS can be bought over the counter and amplify all
sounds at the same amount. Do not give different amounts of amplification at
different frequencies based on the persons hearing loss
