Infrasound describes ubiquitous, low-frequency sound (< 20 Hz) in the environment with a long wavelength below the median hearing threshold, which can nevertheless be heard and tactilely perceived, depending on the sound pressure level and frequency spectrum. In nature, infrasound emissions usually occur only in the low-threshold range. Nevertheless, after strong and chronic exposure to usually artificially generated infrasound emissions, various effects on the ear and the body, sometimes questionably critical to health, can be observed. Correct measurement and assessment of infrasound sources is complex and controversial. Established guidelines are scarce. Innovative research areas include infrasound monitoring for evaluation of natural events and infrasound applications in medicine. In the future, it is hoped that new insights will be gained from infrasound research and that a more extensive classification in occupational medicine will be possible.
次声描述的是环境中普遍存在的低频声音（<20赫兹），其波长较长，低于平均听力阈值，但根据声压级和频谱情况，仍可被听到并通过触觉感知。在自然界中，次声排放通常仅发生在低阈值范围内。然而，在长期强烈暴露于通常是人为产生的次声排放后，可观察到对耳朵和身体的各种影响，有些影响对健康的危害程度存疑。次声源的正确测量和评估复杂且存在争议。既定的指导方针很少。创新研究领域包括用于评估自然事件的次声监测以及医学中的次声应用。未来，希望次声研究能带来新的见解，并在职业医学中实现更广泛的分类。
