    This study presents a computerized method to objectively score auditory brainstem response (ABR) audiometry, reducing subjective analysis. The technique uses signal consistency to reliably detect auditory responses, improving diagnostic accuracy.

    Area of Science:

    • Audiology
    • Neuroscience
    • Biomedical Engineering

    Background:

    • Auditory Brainstem Response (ABR) audiometry is crucial for hearing assessment.
    • Current ABR analysis relies heavily on subjective interpretation of tracings.
    • This subjectivity can lead to variability and potential diagnostic errors.

    Purpose of the Study:

    • To develop and describe a computerized scoring technique for ABR analysis.
    • To reduce subjective decision-making in interpreting ABR test results.
    • To introduce an objective criterion for auditory response detection.

    Main Methods:

    • A novel correlation technique was devised for ABR scoring.
    • The method assumes high consistency of ABR tracings under repeated stimulus conditions.

  • It compares two suprathreshold tracings and a control tracing without an ABR.

    • Main Results:

    • High correlations are expected between two consistent suprathreshold ABR tracings.
    • Low correlations are observed when comparing an ABR tracing with a control.
    • The difference between correlation values serves as the response criterion.

    Conclusions:

    • The computerized scoring technique offers an objective approach to ABR analysis.
    • This method enhances the reliability and reduces subjectivity in ABR interpretation.
    • It provides a robust criterion for identifying auditory brainstem responses.
