JAAA CEU Program

Questions refer to Souza et al, “The Characteristics of Adults with Severe Hearing Loss,” 764–779.

Learner Outcomes:

Readers of this article should be able to:

• Describe the typical audiometric and hearing history for listeners with severe hearing loss.

• Describe the expected effects of severe hearing loss on speech recognition.

CEU Questions:

1. The following is a test of broadband frequency resolution:

   • spectral ripple test

   • gap detection test

   • pitch pattern test

2. The TEN test is based on the premise that, when a tone signal is presented to an area of nonfunctioning inner hair cells:

   • the listener may detect the tone due to efferent activity in the auditory nerve

   • the listener may detect the tone through stimulation of adjacent cochlear regions

   • the listener will be unable to detect the tone at any presentation level

3. In the study, TEN thresholds were measured at the following frequencies:

   • 0.5, 1, and 2 kHz

   • 2, 3, and 4 kHz

   • 4 and 6 kHz

4. What are the three domains of the SSQ questionnaire?

   • speech recognition in background noise from a single talker, multiple talkers, and nonspeech noise

   • slowly spoken speech, spectrally-smeared speech, and quiet speech

   • speech recognition, spatial aspects of hearing, and quality of sound

5. The majority of study participants reported that their hearing loss occurred:

   • after age 30 years

   • after age 50 years

   • after age 65 years

6. The majority of study participants reported that their hearing loss occurred:

   • suddenly

   • immediately following a specific event

   • gradually

7. Among this sample of adults with severe loss, the following hearing aid use pattern was reported:

   • 4 out of 5 of the hearing aid wearers used behind-the-ear hearing aids

   • on average, listeners had worn hearing aids for 10 years

   • most of the participants who wore hearing aids were using linear amplification

8. Results of the TEN test suggest the following relationship between severe hearing loss and dead regions:

   • severe loss does not result in dead regions

   • dead regions occurred for some listeners with severe loss, particularly at higher test frequencies

   • severe loss results in dead regions above 500 Hz

9. When considering whether to include the QuickSIN in an audiometric test battery, this study suggested that:

   • listeners with monosyllabic word recognition below 40% can be expected to have poor speech-in-noise ability

   • because there is no relationship between the QuickSIN and monosyllabic word recognition in quiet, the QuickSIN should always be included as part of the audiometric battery

   • listeners with monosyllabic word recognition above 40% can be expected to have good speech-in-noise ability

10. A regression model indicated that the following factors contribute to the quiet speech score:

    • amount of hearing loss, spectral resolution, and whether or not the listener has dead regions

    • amount of hearing loss, spectral resolution, and age

    • amount of hearing loss, age, and cognitive ability
