From the haunting drone of an Australian didgeridoo to the steady heartbeat of a frame drum, cultures around the world have used sound to facilitate healing for thousands of years. In modern times, scientific research corroborates what native cultures have intuitively known: Sound-based vibration and resonance affect our body at the cellular level.

“As you consider the efficacy of sound vibration in the body it is important to understand that our cells, organs, bones, tissue and cerebral spinal fluid are all composed of water. We are more than 70 percent water, and sound travels four times faster in water than in air. The human body is a natural resonator for sound,” says Ellen F. Franklin, Ph.D., co-founder and chief executive officer of the Acutonics Institute of Integrative Medicine, in Llano, New Mexico, who draws from East Asian medicine, Western science, psychology, physics and music theory to provide sound vibration therapies.

The use of Tibetan or crystal singing bowls, percussion instruments, calibrated tuning forks, gongs, cymbals, chimes, flutes and vocalization affects brain waves by inducing parasympathetic relaxation and modulating pain perception. Directly impacting the vagus nerve, strategic sound applications can alleviate symptoms of depression, anxiety, chronic pain and trauma response, and can be useful for those suffering from post-traumatic stress disorder. Improved sleep quality, heightened creativity and inner calm are additional potential benefits.

 

Cutting-Edge Soundwaves

Histotripsy, a new U.S. Food and Drug Administration-approved technology, employs high-pitched, focused ultrasound energy to break up liver tumors. Similarly, lithotripsy uses ultrasonic shock waves to eliminate kidney stones. Acoustic engineering has also emerged as a promising tool for diagnosis, encompassing brain seizures, heart disease modeling and medication screening.

According to Franklin, co-author of Acutonics From Galaxies to Cells: Planetary Science, Harmony and Medicine, the vagus nerve can be activated via the application of calibrated tuning forks crafted from aerospace-grade metal to key acupuncture points along the body’s meridians (energy pathways). “A number of studies have shown that the vagus nerve is particularly sensitive to sound vibration. DU 20, a key acupoint, addresses stress and trauma, as it can be used to help people wake up the brain and open the mind, and is often used for cognitive disorders and many stress-related symptoms,” she explains, adding that this work is currently being used in clinical settings for patients that do not respond effectively to conventional methods or exhibit drug resistance.

 

Trauma, Tranquility and Brain Health

The rhythmic patterns of electrical activity in the brain produce distinct frequencies that are associated with mental states, emotions and cognitive functions. Throughout our waking and sleeping life, the brain shifts through gamma, beta, alpha, theta and delta states. When we transition to the alpha state using sound therapies like drumming, binaural beats, singing bowls or gongs, we feel calmer and more joyful. Either by playing or listening, therapeutic hand drumming synchronizes the left and right hemispheres of the brain and may be valuable in augmenting cognitive function, retraining the brain after a stroke or improving the management of conditions such as autism, Alzheimer’s disease and attention-deficit hyperactivity disorder.

“The frame drum can significantly influence brain waves, primarily through a process called rhythmic entrainment. The pulses of the drum, especially when played at specific tempos, can induce the brain to synchronize with these rhythms, leading to shifts in brain wave patterns,” says Michael McCullough, a sound healing practitioner at The Healing Sanctuary, in West Chester, Pennsylvania. “Using the perfect fifth, or a 128 Hertz, tuning fork can also boost the body’s production of nitric oxide and balance the autonomic nervous system, releasing antibacterials, antivirals and free radicals on a microscopic level.”

Incorporating therapeutic sound modalities in our healing regimens can broaden the potential for physical and mental well-being. McCullough recommends trying a group sound bath, which is a meditative session where participants lie on a yoga mat or blanket and listen to a diverse range of sounds. He acknowledges that private sessions with a skilled practitioner may also be beneficial because they can be tailored to individual needs and provide a more comprehensive experience.

While Franklin also recommends such sound healing experiences, she cautions, “Frequencies can be used to promote health and well-being, but we always advise people to educate themselves. When working with sound medicine therapeutics, less is more.” Excessive sound therapy—too much or too often—could aggravate the nervous system in some individuals, causing unpleasant side effects such as dizziness, fatigue, disorientation or headaches.
