Human Physiological Response to Frequencies Produced by Animals

Abstract

The purpose of this study is to analyze the physiological response of the human body to frequencies produced by various animal species. This study investigates whether high or low frequencies elicit a stronger stress response in human subjects. This is important in understanding fight-or-flight responses from the perspective of predator-prey relationships. Sixteen Tallahassee State College students were randomly selected as subjects. Baseline heart rate and blood pressure measurements were recorded for each subject. Subjects then listened to five frequencies for one minute each with vitals taken immediately following each frequency. Each frequency is equivalent to the vocalizations produced by five different animals: American alligator, blue whale, lion, wolf, red-tailed hawk. This data was analyzed from an evolutionary biology perspective revealing a trend of measurable stress responses to lower frequencies.
