An Investigation of Effects of Quran Recitation Sound on Human Heart, Brain Signals

As technology advances, man constantly seeks to learn more about interactions among his internal organs and investigate his body’s reactions in times of illness or interventions, such as electric responses of the heart and brain to external stimuli like visual or auditory ones. Hearing a sound and assessing vital signs is one type of intervention. In this research, the effects of the sound of Quran recitation on heart and brain signals in three stages – before, at the time of, and after listening to Quran recitation – have been studied. The heart and brain signals of 50 girl students aged 19 to 24 with roughly similar religious belief levels was registered at a certain time. The objective was to study the effects of listening to Quran recitation on various characteristics, differentiate various states from one another using chaotic processing methods and statistical tests, and examine the accuracy of the results via support vector machines classification. The results show that listening to the Quran has a profound effect on interactions between heart and brain data and causes an increase in data flow between heart and brain signals based on a study of correlation dimension and fractal dimension, and a rise in the interactions between these two vital organs of the body. From a Cybernetics point of view, a rise in interactions in a bio system indicates an increase in the system’s self-organization and efficiency.
