The cardiovascular response to acoustic stimuli.

The purposes of this investigation were to determine whether adults display alterations of cardiac rate under acoustical stimulus conditions and whether such alterations are influenced by signal level. The stimulus consisted of a narrow band of noise centered at 1 000 Hz and presented at 20, 40, 60 and 80 dB SPL. The stimulus was found to produce alterations of heart rate significantly different from variation under non-stimulus conditions, indicating that cardiovascular responses occurred. However, the responses themselves were unaffected by differences of sound pressure level.

Idiosyncratic cardiovascular response of human neonates to acoustic stimuli.

The heart rate response of acoustic stimuli was assssed for 15 newborns between the ages of 24 and 48 hr. Results of the analyses of covariance demonstrated that although the subjects responded to the stimuli, their responses were idiosyncratic in magnitude, direction, and pattern of rate change. Although spectrum and duration of the stimuli were varied, they were found not to be significant sources of response variation.
