Health effects of traffic noise

Abstract
In 57 test persons having worked 1 day under traffic noise (Leq= 85 dB(A) and 1 day without noise (Leq < 50 dB(A), blood pressure and pulse frequency were measured at 1 h intervals and total urine was collected during working hours. Additionally, blood was sampled at the end of each working day. Psychological parameters were assessed by means of questionnaires. Hypothetical mechanisms of the action of traffic noise are discussed.
