Our hypothesis is that if one increases the beats per minute (BPM) then the pitch and volume of the recording will cause the heart to become stressed, leading to a rise in one's heart rate and blood pressure.
Methods:
First, headphones will be placed on the subject. The first set of beeps will be very slow with a high pitch and volume. After listening to the first set, we will measure their heart rate and blood pressure with an arm pump. The subject will then rest for three minutes in order for their heart rate to go back to normal. The second set of beeps will be very slow again but with a low volume and pitch. Again we will measure, and record their data and the subject will rest again for three minutes. The third set of beeps is very slow with a high pitch and low volume. Afterwards we will measure, and record data and the subject will rest. The fourth set will have a very slow BPM and a low pitch and a high volume. We will continue to measure the data and the subject will continue to rest for three minutes. The fifth set we do will have a very fast BPM with a high pitch and volume. The sixth will have a fast BPM with a low pitch and low volume. The seventh set we test will have a fast BPM with a high pitch and low volume. The eighth set will have a fast BPM also but will have a low pitch and a high volume. After each test we will measure the data with the arm cuff, then we will record the data and the subject will rest for three minutes. After all of this, we will compare our data to see if our hypothesis proves to be correct.
Looks promising!
