Increasing BPM, pitch, and volume will induce stress on the heart, causing a spike in heart rate and blood pressure.

To discover the affect sound had on heart rate and blood pressure we to test the tempo, pitch, and volume. For sound our group decided that using beeps would be best since they are artificially created and people will not associate the sound every noise. To keep the experiment from becoming too complicated we varied the volume and the pitch for a slow tempo at 19 BPM and an extremely fast tempo at 178 BPM. In total eight tests will be preformed with each tempo going through high pitch and volume, low pitch and volume, high pitch low volume, and low pitch and high volume. Before we begin we will measure the heart rate and blood pressure. To make the experiment as accurate as possible we are going to wait three minutes in between the soundtracks. The time in between tests will allow the heart rate and blood pressure to return to normal, so the data will no be compromised. Since the experiment will take a long time some people will have to be finish being tested at a later time.
