INTRODUCTION Many investigations have been made on stress response caused by noise, but most of them were concerned with instantaneous or temporary effects of noise. Very few investigated the effects of occupational noise exposure on human stress response over a long period of time. For verifying this we did an analysis of the cortisol/cGMP ratios and the total amounts of cAMP+cGMP of the groups exposed to noise of different intensities.展开更多
