INNER SOUND Tuning Forks
-
Our tuning forks are designed for sound therapy that are for humans and animals used in pairs at the head. US manufactured from high-grade aluminum alloy, they are FDA certified as Type 1 medical devices, available in large & small sets.
-
Our Tuning Forks create a balanced movement of expansion and contraction throughout
the nervous system and field.
This movement produces deep relaxation enabling the body to regenerate and the energy
system to balance and align itself. -
The Basic & Advanced Training provides essential knowledge to maximize the use of the tuning forks in relaxation, complementary therapy, & personal use focus.
-
Frequencies and fork numbers are based on Jack Wilken's research, with course content developed by Arden Wilken, co-founders of INNER SOUND.

Years ago, one student couldn't buy tuning forks after training, so she practiced with 13 dinner forks instead. Another student's ranch family teased her about using "pitch forks" to relax them. They loved it!

Studies
From Practitioner Submissions
Since 2002 in an on-going study, INNER SOUND tuning forks use has shown a significant statistical difference in client-assessed pain and stress levels before and after a session. The assessments were in the positive direction, less pain and stress after the session.
Brain Tracings
This file shows a deeper level of Alpha brainwaves being created during a 15 minute Set of 13 tuning fork session vs 15 minutes of sitting with eyes closed.

More Tuning Fork Practitioner Feedback
"I had the opportunity to use Pair 5, 7, 9, 11, 12, 9 & 5 (Set of 13) for a group of rescue rabbits that have been ill and stressed due to a recent loss of another rabbit. It was amazing. They all came out of their boxes and laid down & stretched out. The one I had worked on before the group session, the most ill, was in the middle pen, & every time I walked back and forth he would stand up like a dog begging, to try and get closer to the sound. It was awesome!"
