Sound rhythm effects on cardiac parameters

Type: article
Abstract: The aim of this study was to find out effects of simple sound rhythms on cardiac parameters of listeners. The rhythms used differed in tempo and intensity, while changes in cardiac parameters (R-R intervals and their variability) were used to assess the effects on the subjects. Experimental design was 3 x 2 within group factorial experiment. Three different levels of tempo (60, 200 and 400 BPMs), and two intensity levels (40 and 80 dB) were used. Eleven subjects participated in the experiment, which consisted of six experimental situations, interpolated with silence situations. Complex effects of different situations were found on cardiac parameters. When sequential effects were eliminated by the use of linear regression, rhythm effects on cardiac parameters were obtained, with a tendency of a decrease in heartbeat frequency, which was more prominent during listening to more intensive and slower rhythms. Heartbeat variability tended to decrease during listening to any rhythm.
