Abstract
The article deals with a study of the influence of exposure to noise (80 dB) upon the corticosteroid, adrenalin, and noradrenalin excretion of male students. Noise exposure appeared to cause a significantly different adrenalin excretion, in so far that among those exposed to noise no drop in excretion occurred in the afternoon. A similar effect, be it to a somewhat lesser degree, was noticed with regard to noradrenalin excretion, whereas in respect of corticosteroid excretion no effect could be traced. These results appear to be in good agreement with findings reported in the literature.
