High-frequency audiometry reveals abnormal hearing thresholds in tinnitus patients with normal hearing. Age-related changes in high-frequency hearing may begin around 30 years old.

Area of Science:

  • Audiology
  • Otolaryngology
  • Hearing Science

Context:

  • Tinnitus is a common auditory perception without an external sound source.
  • Standard audiometry may not detect hearing abnormalities in tinnitus patients.
  • High-frequency hearing loss is increasingly recognized as a potential factor in tinnitus.

Purpose:

  • To evaluate high-frequency (HF) hearing thresholds in individuals with tinnitus but normal pure-tone hearing thresholds.
  • To compare HF thresholds between tinnitus patients and a control group.
  • To investigate the influence of age on HF thresholds in tinnitus patients.

Summary:

  • High-frequency audiometry was performed on 48 tinnitus patients and 30 controls.
  • Significant differences in HF thresholds were observed between tinnitus ears and control ears, as well as between tinnitus and non-tinnitus ears within patient groups (P < 0.01).

  • HF thresholds showed no significant difference between younger age groups (< or = 25 and 26-35 years), suggesting age-related changes may manifest later.

    • Impact:

    • Recommends HF audiometry for tinnitus patients with normal hearing sensitivity to identify subclinical hearing loss.
    • Suggests that changes in HF thresholds are associated with aging, potentially starting around age 30.
    • Highlights the importance of HF audiometry in the comprehensive audiological evaluation of tinnitus.
