Abstract:
The purpose of this experiment was to inform teenagers about the effect different genres of music can have on your heart rate. The heart rates of teens are affected differently when they listen to rock versus classical music. The goal of this experiment was to find out whether teens heart rates would change while they listened to rock versus classical music. The step of the experiment was to have high school students get their heart rate once for sixty seconds without listening to any music. Their heart rate gave us the independent variable. The independent variable …show more content…
was the students resting heart rate before being exposed to either music. Each student then listened to classical music for 20 seconds without their heart rate being measured. After that their heart rate was taken again while they were still listening to the classical music for 60 more seconds. The steps were repeated with rock music to give us the difference in heart rate. The experiment showed us that while students listened to rock music their heart rates were higher than when they listened to classical music.
Background:
A normal heart rate for a teenager, age 15/16 is 70-100 beats per minute.
(Effects of music tempos on blood pressure, heart rate, and skin conductance after physical exertion; University of Wisconsin – Madison; Lab 601, Group 10: Robyn Armon, Adam Fisher, Brittney Goldfarb, Caley Milton) The experiment by the University of Wisconsin says that the effect of music on an individual is a frequently researched topic, especially in regards to emotional response, relaxation, and anxiety. One study found that while listening to a Mozart sonata, participants’ tension increased as tempo increased and decreased with moderate tempos. It is also suggested that music increases learning ability and memory. The increasing number of studies on the effects of music on emotion and memory have led to further research. It has been shown through other experiments that music can have varying effects on heart rate depending on what genre, tempo, or other factors are affecting it. It has been shown that some music can lower heart rate while others can raise it. Elevated heart rate can lead to other illnesses such as tachycardia, a type of increased heart rate that can lead to heart failure, heart defects, and lung and heart diseases. This new knowledge, on heart rate and how it can relate to music, may be used to help patients with high heart rate or stress levels. Doctors can play calm, slower tempo music in hospitals and/ or rehabilitation centers so that patient’s heart rates will lower and they will stay more
relaxed.
Hypothesis
Listening to music with a faster tempo will increase student’s heart rates above their resting heart rate. Student’s heart rates will lower from their resting heart rate when they listened to slower tempo classical music. The independent variable being tested in this experiment is the resting heart rate of students before listening to any music. The dependent variable being tested in this experiment is the heart rate after listening to music.
Material/Methods
Materials: Logger Pro equipment, heart rate monitor, classical instrumental music, rock music, stop watch
Methods:
1. Set up Logger Pro for the heart rate monitor.
2. Set up the heart rate sensor on the subject.
3. Take the subjects resting heart rate.
4. Have the subject listen to classical music for 20 seconds.
5. Start measuring the subject’s heart rate again for 60 seconds while still listening to the classical music.
6. Wait 30 seconds before beginning the next step.
7. Have the subject listen to rock music for 20 seconds.
8. Start measuring the subject’s heart rate again for 60 seconds while still listening to the rock music.
9. Record the results, including the difference between the subject’s heart rates from the resting heart rate to when they listened to the classical or rock music.
10. Repeat for each subject.
Results/Data
All subjects showed drop in heart rate from listening to rock music to classical music. Sometimes the resting heart rate was higher than while the subject was listening to rock music. The data table below shows the subjects resting heart rate, their heart rate while listening to rock music, their heart rate while listening to classical music and the difference between their BPM from their resting to when they listened to classical versus rock music.
The change in heart rate of students
BPM= beats per minute
Discussion/Analysis
Previous research has shown that music can affect heart rate. Different music genres can cause heart rates to either increase or decrease. All five students’ heart rates increased while listening to the rock music with a faster tempo than the slower classical music. This supports the idea that music with a faster tempo causes heart rate to be higher than listening to slower music. The subjects mean heart rate increased an average of 4 beats per minute. There may have been confounding variables in this experiment leading to errors such as if the subject was bothered or comforted by the music due to other reasons, if the subject had been participating in other experiments causing their heart rate to act differently than normal or the low number of tests that we had done. This error could be eliminated by more subjects being used with additional trials on varying days in order to eliminate the possibility that different days could give varying results. Then an average heart rate increase for each person could be calculated. In addition, more experiments looking at different types of music could be done to see if it was the music style that was causing the increase in heart rate or if it was something else.
Conclusion
The hypothesis that rock music will increase the heart rate of teenage students more than classical music was supported by the 100% increase in heart rate in the subjects when listening to the two genres of music during the experiment.
