title: Influence of noise on blood coagulation.
abstract: A study conducted in rats exposed to a continuous noise of 110 decibels over a period of 3 weeks revealed development of significantly prolonged bleeding time, higher plasma fibrinogen content, and progressively shorter activated partial thromboplastin time in test animals. These changes suggest a coagulopathy induced by noise stress.
