Summary
Technically generated infrasound (IS) poses increasing health risks in industrial, transport, and residential settings. Exposure can trigger infrasonic diencephalic hypothalamic syndrome, affecting multiple bodily systems.
Area of Science:
- Environmental Health
- Physiology
- Toxicology
Context:
- Growing prevalence of infrasound (IS) from industrial, transport, and residential sources.
- IS is increasingly recognized as an unfavorable environmental factor impacting human well-being.
- Need for comprehensive understanding of IS health effects and risk assessment.
Purpose:
- To analyze and summarize hygienic problems associated with technically originated infrasound (IS).
- To investigate the pathogenetic features and biological effects of IS exposure.
- To develop a conceptual model and define criteria for IS exposure risk.
Summary:
- Physiological and experimental studies reveal IS impacts subcortical structures like the limbic-reticular complex and hypothalamus.
- Higher IS levels manifest as pathological discomfort, indicative of infrasonic diencephalic hypothalamic syndrome with sensorisomatic and autonomic symptoms.
- Biometric analysis of IS effects (4 Hz, 130 dB) highlights whole-body responses, impacting vestibular, acoustic, neurohumoral, and homeostatic systems.
Impact:
- Established criteria and risk ranking for IS exposure in various environments.
- Provided a conceptual pathogenetic model for understanding IS health impacts.
- Highlights the priority of whole-body responses to infrasound exposure, informing public health strategies.
