Infrawaves: Nature's Early Warning System

Overview

Objectives/Goals The objective of our project was to determine if infrawaves could be used as early warnings for natural disasters, not only by scientists and seismographs, but by people in the danger zones. We worked to determine if humans could sense the infrawaves, and if they could, whether male or female test subjects heard the low frequency tones better. Methods/Materials In order to perform our experiment we needed a Fender Passport Deluxe PD 25(250 watt speakers), an Oscillator, Power Cables, Banana Jack Adapter, Audio Jack Cable, Speaker Cable, Pens, Audio Test Worksheets, A Testing Facility and human test subjects. Using the oscillator to generate low frequency tones, in descending increments of 10 Hz. from 50 Hz. to 10 Hz. ask test subjects to record whether they felt or heard tones. Results Our results proved that infrawaves can be sensed by humans, if with a varying degree of sensitivity. Male teenagers were significantly more sensitive to the subaudible tones than female teenagers. Conclusions/Discussion Not only did we determine that humans can sense infrawaves, we also proved that male teenagers heard the tones better than female teenagers. Also, on later trials, significantly more people sensed the tones, leaving us questioning whether exposure to the tones could provide an early warning system for the public in danger zones, where natural disasters occur frequently.
