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.

Blog 26- Human Experiment Update

In our experiment so far it is a little early to tell if our hypothesis has been supported.  We have experimented on only five people which is not enough to guarantee that a pattern of a raise in heart rate and blood pressure based on frequency, pitch, and volume.  The data somewhat varies from person to person and it will be easier to draw conclusions about the data as we experiment on more subjects.  However, so far it is evident that the sounds that are faster paced have raised heart rate and blood pressure more frequently than the sounds with a slower pace.

Blog 25- Human Experiment Hypothesis and method

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.

Experiment 1:  Giving up a certain food group that is part of your regular diet

Hypothesis:
How and why it would change

Method:
Restrict some element of a group of people's diets [daiy,gluten, etc] and see how it affects different parts of your body [weight, blood pressure, heart rate, etc.]


Experiment 2: To test flexibility improvements

Hypothesis:  If someone stretches multiple times a day their flexibility will increase faster than someone who stretches more than once or not at all in one day.


Method:  Get together a group of people and have someone stretch 1 time a day, another twice, and another 3 times, and another not at all.  We will measure how their flexibility has changed over a set period of time and see if it affects other elements of the body [such as strength]
