In acoustical damping properties we can separate two the most important things which have the most influence. The first is spectral homogeneity which can be achieved using special materials which have high density. Second is a resonance suppression, it is very important because the greater the degree of resonance damping, then the lower is the ability to transfer associated vibrations. When we have a sound system, eg. a turntable with very low damping, can be excited vibration with a frequency close to its resonant frequency (eg. fragment of a music), the system periodically collects and releases energy by changing the amplitude of the cycle which is referred to as a rumbling, which negatively affects the purity of the music.
PanzerWood has been developed bearing in mind these two important properties because from the first strike of any acoustic wave, its immediate dispersal of energy into an amorphous dissipation of acoustic energy, without displaying a definite sonic signature, puts PanzerWood miles ahead of aluminum regarding neutral vibration-absorption performance. Aluminum has been shown to portray characteristic “tones” which ring like a bell at certain pronounced frequencies, and does not dissipate acoustic energy in a homogenous manner. We should be careful, therefore, in how aluminum is used in high performance audio products. In terms of intrinsic acoustical performance, PanzerWood is certainly the better choice. The chart below show indisputable evidence that our reinforced material behaves way better than any aluminium.
The test blocks of Aluminum and PanzerWood in direct calibrated comparison, stuck once each, with acoustical energy decaying over time. In both cases, the image scaling settings of time and level are identical. The strikes occur after 35 milliseconds of silence. PanzerWood is silent again after 120 ms, whereas the Aluminum continues to ring after a half of a second.
