My physicists are supporting the LIBRA effectiveness by applying the following theory.

Yes, it is a fact: if a small focused area (point surface) gets bombarded with sound waves in gas or liquid there are waves both compressing and decompressing, moving away from the center point of the impact. There is a whole different rule that applies to hard materials, since there is different speed occuring near the surface and inside of the mass.

Also, hard materials are resonating differently in thickness and in length direction.

Certain anisotropic materials (like glass) are showing a very obvious difference in the direction the resonance travels. Glass crystals are structured in a way that they allow resonance waves travel only in the direction where they can be transferred from one crystal to another or from one tiny point to another tiny point, making it unidirectional.

In isotropic materials (like Metal) the resonance travels in a sphere direction, forming an omni directional conductivity. Different materials have different resonant conductivity as far as “flowing” speed goes. In glass a given sound wave travels at 9.76m/sec while the same sound wave travels at 2100m/sec in perpendicular direction.

As you can see, glass is a great material for unidirectional sound or resonance conductivity or simply polarizing the resonance. The LIBRA sound or vibration damper pillow utilizes this very unique physical characteristic of glass.

The bottom line is that, the best instrumentation and laboratory measurements are just supporting my own personal listening experience and positive impression which I did find since I am using the LIBRA damper pillow with my Hi-Fi gears.
