Hypothesis: Increasing the BPM, pitch, and volume of a sound will induce stress on the heart, and will cause a spike in heart rate in blood pressure while lowering the BPM, pitch, and volume will lower the heart rate and blood pressure as it comes the heart.
Method: We will run our tests in the music practice room as they are the most quiet rooms on campus. First we will place identical headphones on a group of people. We will measure their starting heart rates and blood pressures and record them. After each sound we will record their heart rate and blood pressure to measure how the sound affected those elements. They will get about a 2-3 minute rest between each set of sound to make sure their heart rate gets down to the normal resting level. Next we will play them their first sounds; all sounds last a duration of 7 seconds; [very slow-high [4186 Hz]- high[70dB]] after that we will record their blood pressure and heart rate again and give them about a two minute rest. Then we will play the second sound [very slow- low[20Hz] - low [30dB] and repeat the recording of blood pressure and heart rate and give the subject another rest. Next we will play them the third sound [very slow- high-[4186Hz] - low [30dB], then record and rest. Then we will play them the fourth sound [very slow- low[20Hz] -high[30dB]. Then record and rest. We will then play them the fifth sound [extremely fast- high[4186Hz] - high [70dB], and then record and rest. Next the sixth sound [extremely fast- low[20Hz]-low[30dB]], and then again record and rest. Next the seventh sound [extremely fast-high[4186Hz] - low[30dB]], and again record and rest. The last sound we will play for them is [extremely fast- low[20Hz]-high[70db], and we will record the final heart rate and blood pressure. After we finish all the tests on all the subjects we need to do we will compare our data, make conclusions, and see if our hypothesis was supported.
Looks promising!
