Have you ever wondered why my high-powered haptic systems require 1400-1800 pounds of solid steel to create the chassis?
Have you ever been like- “WHY did you choose steel and not aluminum, or wood, or something else lighter, Louisa?”
That was intentional. In standard vibroacoustic therapy, devices typically utilize lightweight frames (often a massage table frame) weighing less than 200 lbs. When driven by low-frequency acoustic energy between 20 and 50 Hertz, a low-mass chassis accelerates significantly (violent shaking and destruction) at high power so they can only run about 600 watts maximum, which is underwhelming to the nervous system, especially for larger humans.
At high power, this displacement acts as a mechanical damper absorbing the therapeutic 40hz signal, resulting in significant energy loss and superficial agitation to your bod. Additionally, these sound beds are stuffed with cotton for comfort, dampening the sound waves even further. We went deeper.
To solve this dissipation and decoherence problem, I engineer the chassis of my machines to operate on the principles of inertial reflection, creating what I call the 'Anvil Effect'- and yes im going to be adopting that as a technical term.
By constructing the frame from a solid steel array, we achieve an inertial ratio of greater than 12 to 1 against the average human weight. Because of this massive structural inertia, the steel frame refuses to accelerate and acts as a static inertial anchor.
The acoustic energy cannot displace the frame, so the force reflects into the path of least resistance. This ensures near 100 percent signal transmission directly into the cast acrylic platform, silicon body pads, and the patient. We are not simply shaking furniture; at Vibroacoustix, we use mass to maximize kinetic transfer of the 40hz therapeutic acoustic energy, and we were one of the first to bring 40hz to the mainstream awareness, as other device makers started to follow our lead.
I've created a multilayered acoustic filter/wave guide using a 'sandwich' of materials with decreasing speeds of sound, and driving the wave vectors naturally through impedance matching (im tricking the soundwaves into not bouncing backward by removing sudden structural boundaries), maximizing sound wave transmission efficiency through controlled gradient geometry.
My silicone body pads conduct the sound waves from the acrylic layer, to your body (the target). Silicon has a very similar density to human ligaments and muscle, surrounded by the fluid in our bodies. It makes an excellent coupling material between the human body and the acrylic plexiglass chosen for its elastic properties.
Lastly, my chassis designs are built upon the principals of soundwave mechanics used in designing musical instruments, particularly drums, and woodwinds. Ive added waveguide slits on the arcs of Vibropod to resonate wavelength of 40 hz and all harmonics of 40Hz.
