Abstract
Serum corticosterone and ACTH levels were measured in rats subjected to one and two 30 min intervals of noise (100 dB, 250--20,000 Hz). Both hormones were elevated immediately after noise exposure, dropped below pre-exposure levels after a 2 hr recovery interval and were again elevated with a second exposure. The ratio of immunoactive to bioactive ACTH was slightly depressed after one exposure and markedly depressed after two successive noise exposures (relative to controls) indicating that multiple exposure to auditory stimulation effects a proportionally greater output of bioactive ACTH.Keywords
