A new design concept for an audio dosimeter

E M Clark

    American Industrial Hygiene Association Journal
    |October 1, 1980
    PubMed
    Summary

    A novel audio dosimeter concept accurately measures employee noise exposure by isolating impulsive sounds. This design aims to improve upon existing devices by better aligning with U.S. Department of Labor regulations for noise evaluation.

    Area of Science:

    • Occupational Health and Safety
    • Acoustical Engineering
    • Instrumentation Design

    Background:

    • Current audio dosimeters struggle to accurately differentiate between continuous and impulsive noise exposure.
    • Existing methods may not fully align with the intent of U.S. Department of Labor regulations for noise assessment.
    • Accurate measurement of noise dose is critical for protecting employee hearing.

    Purpose of the Study:

    • To present a design concept for a new audio dosimeter.
    • To develop an instrument capable of accurately evaluating employee exposure to both continuous and impulsive noise.
    • To create a dosimeter that eliminates the influence of impulsive sounds on the calculated employee exposure dose.

    Main Methods:

    • Conceptual design of a microprocessor-based audio dosimeter.
    • Interpretation of existing and proposed U.S. Department of Labor regulations concerning noise exposure.
    • Development of a block diagram illustrating the instrument's architecture and intended operation.

    Main Results:

    • A novel design concept for an audio dosimeter has been proposed.
    • The proposed instrument is designed to accurately measure continuous and impulsive noise exposure.
    • The design specifically addresses the elimination of impulsive sound influence on the noise dose calculation.

    Conclusions:

    • The presented audio dosimeter concept offers a more accurate method for evaluating employee noise exposure.
    • This design aligns with regulatory interpretations for assessing continuous and impulsive noise.
    • The microprocessor-based instrument provides a pathway for improved occupational noise monitoring.
