“…Several studies have looked at the effect of different sound features on heart rate and heart rate variability. In newborns band-limited noise at moderate levels was shown to elicit a reliable increase in heart rate [7]. Schulman reported that this response did not increase significantly with increasing sound [8] however, the stimulus range used was limited to close to the behavioral threshold level.…”

Functional near-infrared spectroscopy (fNIRS) is a non-invasive brain imaging technique that measures changes in oxygenated and de-oxygenated hemoglobin concentration and can provide a measure of brain activity. In addition to neural activity, fNIRS signals contain components that can be used to extract physiological information such as cardiac measures. Previous studies have shown changes in cardiac activity in response to different sounds. This study investigated whether cardiac responses collected using fNIRS differ for different loudness of sounds. fNIRS data were collected from 28 normal hearing participants. Cardiac response measures evoked by broadband, amplitude-modulated sounds were extracted for four sound intensities ranging from near-threshold to comfortably loud levels (15, 40, 65 and 90 dB Sound Pressure Level (SPL)). Following onset of the noise stimulus, heart rate initially decreased for sounds of 15 and 40 dB SPL, reaching a significantly lower rate at 15 dB SPL. For sounds at 65 and 90 dB SPL, increases in heart rate were seen. To quantify the timing of significant changes, inter-beat intervals were assessed. For sounds at 40 dB SPL, an immediate significant change in the first two inter-beat intervals following sound onset was found. At other levels, the most significant change appeared later (beats 3 to 5 following sound onset). In conclusion, changes in heart rate were associated with the level of sound with a clear difference in response to near-threshold sounds compared to comfortably loud sounds. These findings may be used alone or in conjunction with other measures such as fNIRS brain activity for evaluation of hearing ability.

“…The neurophysiological route for this cardiac reflex is not known at the pres-ent time. We do have evidence (SCHUL- MAN, 1973) that it does not require an intact and functioning temporal cortex. The reflexive response is therefore largely peripheral; that is, the presence of heart rate response to threshold stimuli does not guarantee the presence of those higher cortical processes which allow the brain to receive, process, and interpret meaningful environmental stimulation such as language.…”

“…The principle of the Heart Rate Audiometer used in the study reported here is described in Part I of this report (SCHULMAN, 1973). A modification of that instrument, with minor variations in the writeout of the averager and in the rise time of the onset of the stimulus, was used.…”

“…It has already been demonstrated that significant changes in heart rate can be elicited to auditory stimuli at very low intensity levels in normally-hearing subjects (ZEAMAN and WEGNER, 1956; SCHULMAN and WADE, 1970), although this stimulusresponse relationship does not appear to hold true of normal newborn infants under the age of six weeks post-term (SCHULMAN, 1973). The study reported in this paper examined the validity of the technique of Heart Rate Audiometry (HRA) in reflecting the actual clinically-derived profile of hearing loss in a child patient population.…”

“…However, Kaplan (1971) recorded an apparent change of HR In a sleeping subject, when loud tones were presented. Schachter et al (1971) and Schulman (1973) question the existence of a reliable HR-R to a single presentation of an auditory stimulus. Schachter at al.…”
