Figure 1: Results of Effects of sounds at different tempos, frequencies, and pitches on hear rate and blood pressure.

Conclusion:  Our thesis states that raising pitch, tempo, and volume of a certain sound will raise blood pressure and heart rate, while lower pitches, tempos, and volumes will lower heart rate and blood pressure.  This graph supports our thesis for the most part besides the variable of volume.  According to this graph volume does not have as much of an effect on heart rate and blood pressure as we had hypothesized.  However, our hypothesis of higher tempos and pitches was supported as the heart rates and blood pressures of our subjects rose, while lower tempos and slower pitches resulted in a lowering of blood pressure and heart rate.
