Abstract
Summary
The effects of noise on plasma renin activity (PRA) were studied in unan-esthetized rats. An intensity of 115 dB (broadband) was required to increase PRA in animals eating a normal diet; the threshold was only 90-100 dB for sodium-deprived rats. Stimuli at 2000 cps of up to 115 dB were ineffective in elevating PRA.
The authors gratefully acknowledge the advice and assistance of Dr. Joseph E. Hawkins.
