Foundational Aspects of Hearing and Aging: A Research Update

View Course Details Please note: exam questions are subject to change.

1.  Age-related sensorineural hearing loss is typically characterized as:
  1. Sloping low-frequency hearing loss
  2. Sloping high-frequency hearing loss
  3. Bilaterally symmetric hearing loss
  4. Flat hearing loss across the frequency range
2.  In terms of speech perception in noise,
  1. Older adults typically perform better than would be predicted on the basis of their hearing loss
  2. Hearing loss is unrelated to speech understanding in noise
  3. Older adults typically perform worse than would be predicted on the basis of their hearing loss alone
  4. For older adults, speech-in-noise perception can be predicted very well by their hearing loss
3.  Which of the following cognitive abilities has been found to be important in explaining age-related changes in speech perception?
  1. Inhibitory control
  2. Sustained attention
  3. Two-tone suppression
  4. None of the above
4.  The term presbycusis refers to:
  1. Age-related reductions in cognition
  2. Age-related worsening of hearing thresholds
  3. Age-related reductions in temporal processing
  4. Age-related reductions in attentional control
5.  According to current theories of speech perception, older adults will have the most difficulty identifying words:
  1. That sound like many other words
  2. That sound like a small number of other words
  3. That have a lot of different sounds (phonemes in them)
  4. That refer to abstract concepts
6.  People with age-related hearing loss have more trouble in degraded listening conditions. These include:
  1. with background noise, especially in speech noise
  2. with faster speaking rates
  3. accented speech
  4. all of the above
7.  One reason that hearing aids are not completely effective at restoring speech perception is:
  1. Most times they can't make sounds loud enough
  2. They amplify both the target speech and other background noise
  3. They only can amplify low-frequency sounds
  4. They only can amplify high-frequency sounds
8.  The presenter reported that after auditory training:
  1. patients decreased on mean percent correct scores
  2. patients' hearing thresholds improved
  3. improvements were seen on mean percent correct scores and patients reported being more aware of what they were missing
  4. patients felt their hearing improved after training although no change was seen in mean percent correct scores
9.  Almost all theories of age-related changes in speech perception suggest what?
  1. Age-related changes in both hearing and cognition are important to understand age-related deficits in speech perception
  2. If we can improve hearing to normal levels then we can return speech perception to normal levels
  3. Hearing loss is only a minor contributor to age-related declines in speech perception
  4. Both A and B
10.  Which of the following will improve older adults' ability to understand speech?
  1. When a listener can both see and hear a talker compared with listening alone
  2. When speech is produced in a meaningful sentence rather than single words
  3. When speech is produced at a slower speaking rate
  4. All of the above
