My friend recently shared this article with me, and as I found it very informative yet concise, I thought I would share it along with the main points which I found most helpful.
Binaural beat is currently a hot topic in sound therapy, and while many might have heard the name, not all know the meaning.
“Oster showed that when a tone is played in one ear and a slightly different tone is played in the other ear, the difference causes the brain to create a third, internal tone, called a binaural beat. The theory is that this syncs the brain waves in both hemispheres, a process dubbed “brain-wave entrainment””.
The brain-wave entertainment is thought to help keep mind focused, synchronised, and produce delta waves associated with meditation.
On top of that, the binaural beat products are aimed at helping with various health and wellbeing conditions including “stroke or surgery, [aid to] deal with chronic pain, or become more relaxed while undergoing chemotherapy”.
It has also been found that sound can help affect emotions, and that “brain-wave entrainment is an effective tool to use on cognitive functioning deficits, stress, pain, headaches, and premenstrual syndrome”.
