    Bilateral acoustic immittance measurements established normative inter-aural differences for middle-ear function. A disparity exceeding 10 dB in acoustic reflex thresholds may indicate auditory abnormalities.

    Area of Science:

    • Audiology
    • Otoacoustic Emissions
    • Middle Ear Physiology

    Background:

    • Acoustic immittance testing is crucial for assessing middle-ear function.
    • Understanding inter-aural differences is key to identifying auditory pathologies.

    Purpose of the Study:

    • To establish normative data for inter-aural acoustic immittance differences.
    • To define criteria for identifying auditory abnormalities based on bilateral measurements.

    Main Methods:

    • Bilateral acoustic immittance measurements (static immittance, reflex thresholds, reflex growth) were performed on 48 subjects using a 220-Hz probe.
    • Contralateral acoustic reflex data were collected for pure tones and broadband noise across various sound pressure levels.
    • Inter-aural differences were calculated by comparing right and left ear measurements.

    Main Results:

    • No significant differences were found between right and left ear acoustic immittance measurements.
    • Normative inter-aural immittance differences were defined, with 80% ranges being smaller for within-subject comparisons.
    • A difference greater than 10 dB in acoustic reflex thresholds suggested potential auditory abnormality.
    • Mean inter-aural absolute differences in reflex growth ranged from .040-.043 acoustic mmhos.

    Conclusions:

    • Bilateral acoustic immittance measurements provide a reliable method for defining normal inter-aural differences.
    • Deviations in acoustic reflex thresholds exceeding 10 dB warrant further investigation for auditory dysfunction.
    • The study provides valuable normative data for clinical audiological assessments.
