IHS END OF SET ANSWERS AND QUESTIONS SET A+
✔✔A patient/client walks in for a hearing evaluation without an appointment. They are
complaining of hearing difficulty, tinnitus, and increased sensitivity to noise. Case
history reveals that the patient/client just left a music festival two hours prior to coming
to the office. How should the hearing aid specialist proceed? Why? - ✔✔Schedule a
future appointment, auditory fatigue
✔✔Which part of the organ of corti responds to high frequencies? - ✔✔
✔✔basal turn - ✔✔
✔✔What is the energy pathway of sound to the brain? - ✔✔acoustical (outer ear) ->
mechanical (middle ear) -> hydraulic (iiner ear) -> electrochemical (nervous system)
✔✔What are the tree chambers of the cochlea called? - ✔✔Scala vestibuli, scala media,
scala tympani
✔✔What is the difference between hearing and listening? - ✔✔hearing is a
physiological process and listening is assigning meaning to what is heard.
✔✔Where do the central auditory pathways begin? - ✔✔cochlear nucleus
✔✔What is the name for the broad band of neural fibers that connects the auditory
centers in the right and left temporal lobes and enables communication between the
two? - ✔✔corpus callosum
✔✔Specific locations of the cochlea, relay stations, pathways, and auditory cortex
respond to specific frequencies. What is this called? - ✔✔tonotopic organization
✔✔Which type of hearing difficulty is typicaly associated with cognitive ecline, atrophy
of the auditory cortex, social isolation, depression, and cognitive decline? - ✔✔age-
related hearing loss
, ✔✔How does the binaural squelch effect improve the signal to noise ratio? - ✔✔It
integrates binaural signals and their differences into a single percept.
✔✔Which function allows the brain to segregate different streams of simultaneously
occurring stimuli, allowing listeners to focus on a single voice while tuning out others? -
✔✔cocktail party effect
✔✔Patients/clients with asymmetric aspects of auditory function who perceive sound
more clearly in the monaural better-ear condition than binaurally may suffer from what?
- ✔✔binaural interference
✔✔A 36-year-old patient/client comes to the office for a hearing evaluation. Both the
patient/client and their spouse complain that whenever background noise is present,
such as at their favorite restaurant for trivia night, the patient/client has a very difficult
time understanding conversation. Otoscopy is unremarkable. Audiometric evaluation
reveals normal air- and bone-conduction thresholds, excellent word recognition, and a
poor QuickSIN score. How might the hearing aid specialist describe this patient's/client's
hearing? - ✔✔hidden hearing loss
✔✔Each ear is represented at the auditory cortex on each side of the brain, which
optimizes the internal redundancy of the auditory system. Why is this beneficial? -
✔✔damage to the pathways may not lead to hearing loss
✔✔Symptoms such as difficulty paying attention to a conversation, staying on topic,
remembering information, and responding accurately to questions with a family history
of stroke and dementia are consistent with which disorder? - ✔✔cognitive-
communication disorder
✔✔Someone is sitting on a bench in a quiet park talking to someone sitting on their left
side. Then, a loud truck drives past on the street which is on the person's right side.
What effect improves the person's SNR by 3-10 dB? - ✔✔head shadow effect
✔✔What is the interaural attenuation when using a bone conduction oscillator? - ✔✔0
dB HL
✔✔What are the units of the x and y axes on an audiogram? - ✔✔x: Hertz (Hz); y:
deciBels hearing level (dB HL)
✔✔Describe the symbols used to document masked air conduction thresholds. -
✔✔Masked air conduction thresholds are denoted with a blue square for the left ear and
a red triangle for the right ear.
✔✔A hearing aid specialist is instructing a 55-year-old patient/client on completing air
conduction testing. The hearing aid specialist says, "We are going to measure the
