Age-related hearing loss begins in middle age, affecting high frequencies initially. Gender differences in hearing decline emerge, with males showing faster initial decline, but this evens out in older age groups.

Area of Science:

  • Audiology
  • Gerontology
  • Public Health

Background:

  • Age-related hearing impairment (presbycusis) is a common sensory deficit.
  • Understanding gender-specific patterns of hearing loss progression is crucial for targeted interventions.
  • Previous research indicates variations in hearing acuity between genders across the lifespan.

Purpose of the Study:

  • To investigate age-related hearing threshold changes in a general population sample.
  • To analyze gender differences in the onset and progression of hearing impairment.
  • To identify specific age ranges and frequencies affected by hearing loss in males and females.

Main Methods:

  • Audiometric testing of hearing thresholds was conducted on 224 individuals (128 female, 96 male) in Tbilisi.

  • Hearing was assessed across a wide frequency range (0.125–16 kHz).
  • Subjects with occupational noise exposure or confounding medical histories were excluded.

    • Main Results:

    • Initial signs of age-related hearing impairment were observed in females aged 40-49 and males aged 30-39, primarily affecting high frequencies.
    • Hearing loss magnitude increased and extended to lower frequencies in subsequent age decades (50-79 years).
    • Males exhibited a more rapid decline in hearing thresholds between ages 30-59, leading to increased gender differences, which then diminished in older age groups as female hearing loss accelerated.

    Conclusions:

    • Age-related hearing impairment manifests differently in males and females, with distinct onset ages and progression rates.
    • Gender-based disparities in hearing acuity evolve across the adult lifespan.
    • These findings highlight the importance of considering gender in the study and management of presbycusis.
