Noise and stress: a comprehensive approach

J C Westman, J R Walters

    Environmental Health Perspectives
    |October 1, 1981
    PubMed
    Summary

    Sound processing in the brain explains how noise becomes a stressor. Understanding these auditory responses is key to mitigating noise

    Area of Science:

    • Auditory neuroscience
    • Environmental psychology
    • Public health

    Background:

    • Hearing serves crucial alerting and warning functions, directly influencing emotions and actions.
    • Sound processing in the brain involves neural mechanisms like the auditory orienting response, startle reflex, and defensive response.
    • These responses can trigger 'fight or flight' mechanisms, leading to stress-induced physiological changes.

    Purpose of the Study:

    • To provide a biological and psychological framework for understanding how sound acts as a human stressor.
    • To review existing literature on the health and mental health effects of noise.
    • To propose an integrated model for noise research and public policy.

    Main Methods:

    • Outline of sound processing in the brain.
    • Review of scientific literature on noise and health effects.
    • Development of an integrated model for noise research.

    Main Results:

    • Sound processing directly links auditory stimuli to emotional and behavioral responses.
    • Neural mechanisms translate sound into action and physiological stress responses.
    • Existing research on noise effects may lack a full understanding of human sound processing.

    Conclusions:

    • A comprehensive understanding of how humans process and react to sound is essential for effective noise research and mitigation.
    • The proposed integrated model offers a holistic approach to noise research and public policy formulation.
    • Minimizing the harmful effects of noise requires a deeper appreciation of the biological and psychological underpinnings of auditory perception and response.
