Here is what I would consider the true “magic” behind the weighted tuning fork when it comes to therapeutic methods for resolving pain and mobility restrictions in the body.
Tuning forks produce more than just the listed frequency. The image shows a frequency analysis I conducted on the 128hz weighted tuning fork we use in our Healing Center. I recorded it on a Zoom H6 digital audio recorder and performed a frequency analysis using the Audacity software. This is something I did often in the Navy to determine how certain sound sources and individual frequencies would travel within the underwater environment.
In the image, you can clearly see that the loudest source is the 128hz fundamental frequency followed by the second harmonic and 5 other harmonics before we start to see the typical “dropoff” as higher frequencies tend to have less strength and travel less distance. Only we find something unique to this tuning fork where frequency spikes are found rising above the sound floor above 4000hz with clear spikes above 20,000hz. The significance of this image is the fact that weighted tuning forks (and the 128hz fork specifically) produce multiple strong frequencies well into the ultrasonic range beyond the fundamental or base frequency listed on the fork.
This spike at 20,000hz might seem insignificant, but a spike like that is not only a big deal for audio quality it’s a much bigger deal for the affects it has on human tissue. There is a well documented and researched phenomenon around ultrasonic vibration generating cavitation bubbles which changes the membrane permeability across cell membranes and all other membranes in the body. Therapies have been created around using ultrasound machines in the Megahertz range for reducing fat cell volume and delivering drugs and gene therapy to specific locations inside the body through sonoporation by inducing cell membrane permeability. When the frequency and strength are turned up, we find a more destructive effect with the destruction of cell membranes in studies focusing on cancer treatments using sound vibration.
With lower frequencies and strength from a tuning fork, the effects are much less severe without damaging the tissue and membranes. Our methods with the tuning fork still provides the cavitation effect to change the permeability of membranes holding in pressurized fluids throughout the body. Our research also shows a rapid draining of fluid pressurizes pockets when the membrane has been stretched with the tuning fork. The use of weighted tuning forks makes this method much more accurate and effective than an ultrasound device which delivers vibration from the skin surface with no reliable pressure or stretching of the underlying tissue and membranes. Ultrasound devices use higher frequencies capable of vibrating the tissue to such a high degree that it could damage surrounding cells due to heat build up.
Based on this information, it is clear that the fundamental frequency is not what causes the weighted tuning fork to produce therapeutic results. These ultrasonic frequencies are generated elsewhere in the tuning fork from the other oscillations as a result of the impact of the weights against the striking surface. Although the fundamental frequency is the loudest source, it is not responsible for most of the work in a therapeutic setting. Tissue and membrane permeability requires frequencies in the ultrasonic range to generate cavitation bubbles.
In light of this information, should we spend our time looking for the right frequency for specific cells, tissue, organs, glands, and systems? Stay tuned for more information on these areas as well. It turns out that most tissue, organs, and glands are created and protected by the same exact anatomical structures which would also support a different theory than the community accepted cell resonance theory or expectations that one frequency is required for a specific type of tissue, organ, or gland.
