    This study analyzes hearing threshold data to predict age-related hearing loss (presbyacusis) in males and females. A formula and coefficients are provided for estimating hearing levels across various frequencies and ages.

    Area of Science:

    • Audiology
    • Biostatistics
    • Gerontology

    Background:

    • Presbycusis, or age-related hearing loss, is a significant public health concern.
    • Existing data on hearing thresholds requires standardized analysis for accurate prediction.
    • International standards for audiometric data are crucial for research and clinical applications.

    Purpose of the Study:

    • To critically evaluate and analyze numerical data on presbycusis from existing literature.
    • To develop a predictive formula for the age effect on hearing thresholds in screened populations.
    • To enable estimation of hearing level distributions across frequencies and ages.

    Main Methods:

    • Literature review and critical analysis of pure-tone hearing threshold data.
    • Derivation of a mathematical formula for age-related hearing changes.

  • Development of tabulated coefficients and rules for estimating hearing level distributions.

    • Main Results:

    • A formula was derived to predict the age-related hearing threshold shift.
    • Coefficients and rules were established for estimating hearing levels from 0.125 to 12 kHz.
    • The methodology allows for detailed prediction of hearing loss progression with age.

    Conclusions:

    • The derived formula and coefficients provide a robust method for predicting presbycusis.
    • This work supports the standardization of normative audiometric data by the International Organization for Standardization (ISO).
    • The findings are valuable for audiological research, clinical practice, and hearing healthcare policy.
