The Ramifications of Sound Stimuli on the Human Autonomic Nervous System

Overview

Objectives/Goals By using different tones to cause differing effects in people I found whether or not people#s heart rates are changed by the tones I can find which tones soothe and calm people, and which tones cause the opposite response. Methods/Materials By using speakers to project different sounds produced through a media player, I record the information gained by heart rate monitors onto data sheets. Results The Ocean Waves sample on average lowered the heart rate, followed by the Thunderstorm sample. The Fast Tempo music increased the heart rate the greatest, followed by the Babbling Brook sample, then the Slow Tempo music sample. Conclusions/Discussion My hypothisis was partially correct, the Fast Tempo music sample did increase the heart beat, although the Thunderstorm lowered the heart beat instead of raising it. The Ocean Waves sample was the stimuli that lowered the heart beat the most, followed by the Thunderstorm, while the Babbling Brook stimuli increased the heart beat.
