Otoadmittance in normal subjects

M Z Himmelfarb, J Lessing, E Shanon

    The Laryngoscope
    |July 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    Otoadmittance audiometry established normative data for young adults. Findings provide reference values for static admittance, middle ear pressure, and acoustic reflex thresholds in normal-hearing individuals.

    Area of Science:

    • Audiology
    • Otoacoustic Emissions
    • Hearing Science

    Background:

    • Otoadmittance audiometry is crucial for assessing middle ear function.
    • Establishing normative data is essential for accurate clinical interpretation.
    • Previous studies may lack comprehensive data for specific age groups.

    Purpose of the Study:

    • To determine normative otoadmittance values in young adults (18-30 years).
    • To evaluate middle ear pressure and acoustic reflex thresholds.
    • To compare findings with existing literature.

    Main Methods:

    • Otoadmittance audiometry was conducted on 18-30 year olds with normal hearing.
    • Static admittance, conductance, susceptance, curve width, and middle ear pressure were measured.

  • Acoustic reflex thresholds for pure and interrupted tones were assessed.

    • Main Results:

    • Mean values and standard deviations for static admittance, conductance, and susceptance were calculated.
    • Middle ear pressure and acoustic reflex thresholds were determined.
    • Data from subjects with tympanic membrane abnormalities were analyzed separately.

    Conclusions:

    • Normative otoadmittance values were established for young, normal-hearing adults.
    • The study provides a valuable reference for audiological assessments.
    • Comparison with literature validates the current findings.
