The manual LOT test

J E Lankford, W A Meissner

    Journal of the American Audiology Society
    |May 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    A manual version of the lengthened off-time (LOT)-Békésy test is feasible for audiology. This cost-effective method produced results equivalent to the automatic LOT test for nonorganic hearing loss subjects.

    Area of Science:

    • Audiology
    • Hearing Science
    • Diagnostic Testing

    Background:

    • The lengthened off-time (LOT)-Békésy test is a standard audiological assessment.
    • Automatic recording devices are typically required for the LOT-Békésy test, increasing costs.
    • Exploring manual variations can enhance accessibility and cost-effectiveness in audiology.

    Purpose of the Study:

    • To determine the feasibility of a manual variation of the LOT-Békésy test.
    • To assess if a manual LOT test can yield comparable results to the automatic version.
    • To evaluate the potential for using existing audiometers without additional equipment.

    Main Methods:

    • A manual LOT-Békésy test procedure was developed, requiring the audiologist to manually adjust the attenuator.

  • Ten subjects with nonorganic hearing loss were tested.
  • Results from the manual LOT test were compared with those from the automatic LOT test.

    • Main Results:

    • The manual LOT-Békésy test procedure was found to be feasible.
    • Results obtained using the manual method were equivalent to the automatic LOT test.
    • The manual technique demonstrated reliability in assessing nonorganic hearing loss.

    Conclusions:

    • A manual variation of the LOT-Békésy test is a viable and cost-effective alternative.
    • This manual method can be implemented with most wide-range audiometers.
    • The findings support the adoption of this manual procedure in clinical audiology settings.
