IMPACT OF SINGING BOWL PLAYING ON THE BRAIN USING EEG

Singing bowl/Himalayan bowl is a type of standing bell played by rubbing its rim with a wooden mallet. They produce a variety of vibrations to reinstate the natural frequencies of unhealthy and out-of-tone parts responsible for thoughts, emotions and behaviours. The electrical impulses released in the brain during the communication of neurons are known as brain waves. In this work, sixty-five trained subjects of various categories play the singing bowl, and their EEG signal values are taken before playing, during the playing of the bowl and after playing. The signals are recorded during the above durations. Various brain signals (delta, theta, low alpha, high alpha, low beta, high beta and gamma), are observed and analysed for this purpose. These waves are ranked for each instance. The contribution of brain waves at each rank before and after playing the bowl are compared to extract the impact of singing bowl playing on the brain.
