Non-auditory health effects of noise are the result of stimulation of the vegetative nervous system, reticular formation, and cortical and subcortical brain centers. Noise acts as a stressor activating the mechanisms of stress reactions in the organism. Noise is not only a physical stimulus, but also an individually experienced noise-event with a corresponding emotional reaction. An insufficient ability to cope with the noise can lead to inadequate neuro-endocrine reactions as well as to diseases of the regulatory systems. In our study we investigate the effect of community noise, especially road traffic noise exposure on a selected group of young healthy individuals in the urban environment.
