How Does It Work? The therapeutic effect of relaxing sounds seems to have a scientific definition of its own. When the human brain is relaxed it produces more alpha brain waves. When a person is stressed out, his brain produces more beta and theta waves. Beta and theta waves are faster changing brain waves than alpha waves. Within the fight-or-flee logic of a sudden stressful situation, the human brain processes seem to speed up to act faster. This can be helpful in short, specific moments, but it is counter productive when it becomes a chronically state of being. A relaxing tune can help with its sounds typically rich in frequencies that are similar to our alpha type brain waves. The mind is always open to suggestions and thus when a person is agitated or tensed, relaxing sounds, rich in alpha like frequencies, can actually bring brain frequencies down from theta to beta to eventually alpha brain waves, changing the overall mood of the listener during this process. It's a scientific fact: A relaxing melody can help a person to get at ease. When a person listens to a piece of music that he finds relaxing, he can focus on that, forgetting his agitation and tension. His/her breathing slows down a well as the heart rate and blood pressure.
