Influence of Music on HRV Indices Derived from ECG and SCG

Music surrounds us every day and fulfills many functions. Its influence on human physiology has been widely described in the literature. In order to evaluate quantitatively this influence, we used heart rate variability (HRV) analysis on signals acquired before listening to the music and after listening to the music for 50 min. The following HRV indices were considered: AVNN, SDNN, RMSSD, pNN50, PLF, PHF, LF/HF, \(SD_1\), \(SD_2\), EA, VLI, and VAI. We observed no statistically significant differences between HRV indices calculated on signals registered before and after 50 min of listening to the music, although we observed the increase of PLF.
