    The Welch Allyn AudioScope can reliably screen hearing using specific eartips. This study identified the best eartip configuration for accurate audiometric data collection.

    Area of Science:

    • Audiology
    • Medical Devices

    Background:

    • The Welch Allyn AudioScope is a handheld device for hearing screening.
    • Accurate audiometric data is crucial for effective hearing assessment.

    Purpose of the Study:

    • To evaluate the Welch Allyn AudioScope as a reliable audiometer screening instrument.
    • To determine the optimal eartip configuration for audiometric data accuracy.

    Main Methods:

    • Utilized a threshold, loudness balancing technique for evaluation.
    • Compared two eartip configurations for reliability.
    • Applied the American National Standard Method for Coupler Calibration of Earphones.

    Main Results:

    • Reference threshold sound pressure levels were developed for the AudioScope.
