Age and the human cochlear traveling wave delay

Summary

Mild hearing loss does not impact cochlear traveling wave delay. However, traveling wave delay slightly increases with age, suggesting age-related changes independent of hearing thresholds. This research uses distortion product emissions (DPEs) to assess cochlear function.

Area of Science:

  • Auditory Neuroscience
  • Otoacoustic Emissions
  • Human Physiology

Background:

  • Aging affects cochlear mechanics and filtering properties.
  • Hearing threshold losses, common with age, also influence cochlear filtering.
  • Distortion Product Emissions (DPEs) offer an indirect measure of cochlear traveling wave mechanics.

Observation:

  • Traveling wave delay was estimated from DPE phase measurements in 91 subjects aged 22-78.
  • Subjects had auditory thresholds ranging from normal to mild cochlear hearing loss.
  • Measurements were taken across eight frequencies using a psychophysical test and specialized software.

Findings:

  • Mild hearing losses did not significantly affect traveling wave delays.
  • A slight increase in traveling wave delay was observed with advancing age.

  • Maximum DPE amplitude decreased with both age and increased pure-tone threshold.

    • Implications:

    • Age-related, threshold-independent factors may alter cochlear properties like basilar membrane stiffness.
    • The relationship between maximum DPE amplitude and hearing threshold predicts hearing ability.
    • DPE phase measurements provide insights into age-related cochlear mechanical changes.
