Music and stress
Student Personal Work (French T.P.E): experiment to see consequences on 6 students at the same time, of listening different music on physiological parameters, as heart rate and skin resistance.
Correlations of differents sudents results are calculated.
6 interfaces
Heart rate
Stress sensor
Music diffusionNo vision
Result of experiment Music and stress
Calculation shows a correlation between emotion measure of differents students during the experience.
The emotion seams to increase each time there is an important change in the music.
Different objective reactions for different persons. In some musical sequences, emotion seems to decrease in certain persons and increase in others.
