In traditional standards, rules and safety regulations environmental stress is assessed by connecting intensity and duration by means of a multiplication, i.e. a mutual settlement of high workload and short duration and a low stressor height but a longer lasting exposure. This principle is based on the hypothesis that equal energy dose-also known for dynamic muscle work as the principle of equal work-involves equal human related effects. But such guidelines are more closely related to physics than to physiology. Yet, ergonomics and occupational medicine have to concern themselves not only with physics but principally with physiological cost as welt as short and long-term effects on humans in the domain of strain. Current evaluation procedures for the assessment of noise exposures were reviewed from an ergonomics point of view.
