Summary

Simulated high-frequency hearing loss in young adults increased speech errors, mimicking geriatric hearing issues. These errors may stem from hearing loss, not expressive language deficits.

Area of Science:

  • Audiology
  • Speech-Language Pathology
  • Gerontology

Background:

  • High-frequency hearing loss is common in older adults.
  • Speech perception difficulties are often attributed to language impairments.

Purpose of the Study:

  • To investigate the impact of simulated high-frequency hearing loss on speech production in young adults.
  • To differentiate speech errors caused by hearing loss from potential language deficits.

Main Methods:

  • Young adults with normal hearing participated.
  • Three listening conditions were used: normal hearing and two levels of simulated high-frequency hearing loss.
  • The Phrase Repetition subtest of the Boston Diagnostic Aphasia Examination was administered.

Main Results:

  • Significant differences in speech errors were observed across conditions.
  • The greatest number of errors occurred with the most severe simulated hearing loss.
  • This suggests hearing loss can directly impact speech repetition accuracy.

Conclusions:

  • Simulated high-frequency hearing loss can lead to increased speech errors in young adults.
  • Speech errors in individuals with hearing loss may be misattributed to expressive language impairments.
  • Audiological assessment is crucial for accurate diagnosis.
