So many of you know that at Meadowbrook Educational Services we highly recommend sound therapies for increased change in performance. Many people have never heard of sound therapy before and many want to know how it works. This presentation that I have summarized below is a professional level presentation about how our brain responds to bone conduction (how the vestibular system responses to vibrations). It cover the components and interaction of the auditory & vestibular systems. *This presentation only covers the traditional vestibular system (not the overall nervous system response to bone conduction).
In 2007 Sheila Allen’s (M.A., OTR, BCP) presented for an hour and a half about Vestibular Responses to Sound at the ABT International Conference.
The video shared below is 1.5 hours, I’ve shared the most important points for the average listener.
- The inner ear is part of the vestibular system – the part of our body that helps us balance and know where we are in space.
- Force = mass + acceleration; and acceleration is created by our head positions & movements and by vibrations & sounds.
- When the Vestibular (balance/perception) system is weak people have less mobility, confidence, concentration, performance function, and less ability to feel safe.
- When the system is activated the force changes how the hair cell moves which triggers transmission through afferent fibers of the 8th cranial nerve. Vestibular hair cells are most sensitive between 500-1000 hertz – which would be the GREEN & ORANGE zones in your TLP kits.
- Information presented comes from research as far back to the 1920′s through 2007.
