A Preliminary Study about the Music Influence on EEG and ECG Signals

Abstract

In this work, music is used to elicit emotions and the impact produced by it on the electrocardiogram and electroencephalogram signals is measured. Test consists a sequence of 12 songs where each one is played during 1 minute. Songs were grouped in 4 sets based on pleasant/activation level. In this preliminary study, 6 male subjects realized the trial. Individuals scored each song using Self-Assessment Manikin (SAM) survey. Biosignal parameters were analyzed with Kruskal-Wallis test (KWT). Although the sample of the subjects on whom the test was performed is small, significant variation is observed in 3 parameters extracted from the electrocardiogram when features are grouped using SAM values from survey filled in by subjects. These parameters show an increasing of heart rate with arousal level and when songs are not totally matched with individual preferences. The use of information extracted from biosignals in therapies for individuals with low interaction is proposed for future studies.
