Brainwave Entrainment
Sound healing also utilizes the phenomenon of brainwave entrainment. Different sound frequencies can influence the electrical activity in the brain, guiding it into specific states such as alpha, theta, or delta waves. These states are associated with relaxation, deep meditation, and rejuvenating sleep, respectively. By entraining the brainwaves, sound healing can induce a profound sense of calmness and mental clarity.
Binaural beats are an effective way of entraining the brain into these different states and have many different applications. I find them particularly effective when I need to focus on a project, or when I want to quiet my mind and relax. They can be easily found online, although you need to pick them with your goals in mind, or you might find yourself drifting off to sleep when you’re trying to be productive. Listening to them with headphones is essential to get the binaural effect. More on that coming up in a future post.
