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.

Stress measure

Heart rate

Push back or front and see which muscle react first (foot extensor)
