What is the Biofield?

In 1994 a panel of scientists at the National Institute of Health chose the word “biofield” to describe the field of energy and information that surrounds and interpenetrates the human body. The biofield is composed of both measurable electromagnetic energy and hypothetical subtle energy, or chi. This structure is also referred to as the "human energy field" or "aura."

While western science has yet to describe and measure this energy, other cultures, especially ancient Indian or Vedic cultures describe it extensively. The term "chakra" (wheel) in Sanskirt, refers to spinning energy vortices which are seen as structures in the body’s subtle energy anatomy. Not coincidentally, within the body at each chakra location there is a corresponding large cluster of nerves or plexuses.

One way of understanding subtle energy is through the analogy "subtle energy is to electromagnetism as water vapor is to water."  Just as we do not measure water vapor with the same tools we use to measure water, we can’t use the same tools to measure subtle energy we would use to measure electricity.  Subtle energy is higher, finer, more diffuse and follows slightly different laws.

Another word for this energy is "bioplasma."  Bioplasma is a diffuse magnetic fluid which surrounds all living beings. Like a fluid, it can be of varying viscosities and densities. In Biofield Tuning (also known as "sound balancing"), we see the human biofield as a bioplasmic toroid-shaped (doughnut-shaped) bubble which surrounds the body at a distance of about 5-6 feet to the sides and 2-3 feet at the top and bottom; bounded by a double layer plasma membrane much like the protective boundary which defines the earth’s upper atmosphere.  

Biofield Tuning founder, Eileen Day McKusick’s research has shown that all of our life experiences appear to be stored magnetically in standing waves within this medium. The biofield is then compartmentalized, with the record of different emotional experiences being stored in different, stratified locations within the field. Additionally, it is timelined, with information at the outer edge of the field relating to gestation, birth and earliest childhood and information close to the body being recent or current. All other years fall in between like the rings of a tree.

Different emotions produce different frequency signatures.  These are reflected in the overtones (or harmonics) of the vibrating fork. For example, fear has a very distinct pulsing quality to it. Other emotions, such as guilt, grief, and anger, all have their own unique signatures and their own unique locations in the biofield.

Eileen’s extreme sensitivity to vibration, as well as a somewhat curious natural understanding of the language of frequency, has enabled to her to “map the biofield” much like neuroscientists have mapped the brain. Over the course of her research, a universal pattern has appeared - the same emotions, or states of mind, appear to be housed in the same areas of the biofield and body of each person.


Record of periods of stress or difficulty can be located in the biofield by passing a tuning fork slowly through this subtle energy field.  These experiences show up as distortions or “noise” and resistance in the signal which can be perceived by both the practitioner and the person receiving a session. Depending on where within the biofield anatomy these distortions present, the approximate age and emotional tone of the experience can be determined by referring to the map.


Being able to identify the “source point” of the stressor in the field and neutralize it gently with sound has, in clinical practice, produced predictable, repeatable and consistent outcomes of symptom reduction and even elimination, sometimes in just one session.

Using the Biofield Anatomy Map the Biofield Tuning process is designed to locate, harmonize, and release areas of noise and resistance in the body's electrical system, making it possible for the individual to activate previously inaccessible potential and move forward with a more empowered and balanced perspective.

The Biofield Anatomy is outlined in detail in Eileen’s book, Tuning the Human Biofield: Healing with Vibrational Sound Therapy.
