Mental illness has reached an all time high in the world, and yet the modern day medicines to relieve symptoms have gained controversy. This is, in part, why people have dug up the past to better understand alternative ways of healing.
Sound, for instance, has been a tool for promoting the physical and emotional health of the body for as long as history can account for, deeply rooted in ancient cultures and civilizations. The ancient Egyptians used vowel sound chants in healing because they believed vowels were sacred. Tibetan monks take advantage of singing bowls, which they believe to be “a symbol of the unknowable” whose “vibrations have been described as the sound of the universe manifesting.”
“Our various states of consciousness are directly connected to the ever-changing electrical, chemical, and architectural environment of the brain. Daily habits of behavior and thought processes have the ability to alter the architecture of brain structure and connectivity, as well as, the neurochemical and electrical neural oscillations of your mind.”
Psychoacoustics is the scientific study of the perception of sound, and it has fueled researchers paths to better understand how it can be used as medicine. For instance, in 1973, Dr. Gerald Oster, a medical doctor and biophysicist, proved, in his research paper, “Auditory Beats in the Brain,” how sound affects the how the brain absorbs new information, controls mood, sleep patterns, healing responses, and more, and how quickly. Thus, specific frequencies of sound and music can be used to generate neurotransmitters such as serotonin.
To understand the fundamentals of sound in healing, we must first understand our brain waves. The nucleus of our thoughts, emotions, and behaviors, is the communication between neurons. Brain waves are generated by way of electrical pulses working in unison from masses of neurons interacting with one another. Brain waves are divided into five different bandwidths that are thought to form a spectrum of human consciousness.
The slowest of the waves are delta waves (.5 to 3 Hz), which are the slowest brain waves and occur mostly during our deepest state of sleep. The fastest of the waves are gamma waves (25 to 100 Hz), which are associated with higher states of conscious perception. Alpha waves (8 to 12 Hz) occur when the brain is daydreaming or consciously practicing mindfulness or meditation.
