Biofield Tuning (also known as "sound balancing") is a sound therapy method that works with the power of sound and the human biofield to help alleviate conditions such as pain, anxiety, insomnia, PTSD, emotional overwhelm, digestive issues, adrenal fatigue and more.

Practitioners work with the "Biofield Anatomy Map", a compilation of Biofield Tuning's founder, Eileen Day McKusick’s 20+ years of biofield observations. Areas of dissonance can be pinpointed to a specific age and type of memory. For example, one might find a strong sense of sadness at age 12 or birth trauma at the outer edge of the biofield.

Biofield Tuning is based on the premise that the human biofield - the energy field that surrounds and permeates our bodies - is inextricably connected with our conscious and subconscious mind, including all of our memories. All physical, mental and emotional disorders can be perceived as "dissonance" in our energy fields. Biofield Tuning is able to diminish and resolve this dissonance and in doing so, alleviate and even eradicate the corresponding physical, mental and/or emotional symptoms.

During a Biofield Tuning session, a client lies fully clothed on a treatment table while the practitioner activates a tuning fork and scans the body slowly beginning from a distance. The practitioner is feeling for resistance and turbulence in the client's energy field, as well as listening for a change in the overtones and undertones of the tuning fork. When the practitioner encounters a turbulent area he/she continues to activate the tuning fork and hold it in that specific spot. Research suggests the body's organizational energy uses the steady coherent vibrational frequency of the tuning fork to "tune" itself. In short order, the dissonance resolves and the sense of resistance gives way. This appears to correspond to the release of tension within the body.

Holding an activated tuning fork in the area of a traumatic memory or another difficult time period produces repeatable, predictable outcomes. The sound input seems to help the body digest and integrate unprocessed experiences. As the biofield dissonance subsides, clients generally report feeling "lighter" and a diminishment or resolution of their symptoms.

One might interpret this as a kind of targeted nervous system biofeedback. Eileen has come to see this process as "consciousness hacking", a side-door entry into the psyche - working with what has been hidden in plain view - which assists people in making changes they otherwise could not on their own.
