Plasma ACTH and corticoid values were recorded together with EEG changes in 5 subjects before, during and after study (controls) and studying with 82 ± 2 dBA continuous noise, 92 ± 2 dBA continuous noise and 92 ± 2 dBA discontinuous intermittent variable test noise in 4 different sessions. The general trend of hormonal levels in plasma was toward lowering between 8 p.m. and 1 a.m. During administration of 92 dBA continuous noise a rise in plasma corticoids was observed for a limited time during noise administration, as well as at the end of the noise and after stopping noise. Increase of plasma ACTH levels was observed also after stopping 92 dBA continuous noise. EEG changes were observed sometimes during 82 dBA continuous noise and more consistently during 92 dBA continuous and discontinuous noise and were mainly referable to synchronization of the alpha rhythm. The findings are discussed and an interpretation is suggested.
