...tiny metal bowls riding atop a trident cradle whose shaft is embedded in a grain-oriented, well seasoned soft or hard Maple wood sliver, with the bowls made from copper, silver, gold or Platinum alloys like Japanese or Tibetan singing bowls, winged protrusions added like an inverted Wagner warrior helmet....his resonators decompress air pressures zones to act as acoustic equalizers. The density of his alloys is given as 10.5 for the silver and basic cups, 15.5 for the gold and gold special versions and 21 for the Platinum. Higher density translates to "higher tension, less pressure". By activating the passive resonators through air excitation in a room -- this needn't be done by loudspeakers but could be from refrigerators, air conditioners, heaters, traffic noise and all the other constituent of the background din that so plagues modern city civilization -- the damping factors for different frequencies are altered and some of the excess energy in the room is neutralized.
The resonators also become focal points for intense overtone radiation. That is denser at their points of origin than in the surrounding air. As directional organs, our ears key into these radiation sources and our acoustic perception of the space we're in is altered. Again, no music needs to be played to sense this spatial overlay. Speech will do, or the sound of our own foot fall. Being completely passive, the resonators can only be activated by received energy. As HF modulators, a full-range input obviously isn't needed. Franck Tchang has used a spectrum analyzer to corroborate this action up to 3GHz. By affecting the ordinary acoustic damping through adding parallel values from the resonators, original HF content reappears. It becomes audible again and rebalanced against the LF energies. Treble decays improve and the subjective impression of audible space deepens. The resonators equalize air pressure differentials and can be installed in a fridge, mailbox or outside a room. Distance will not affect their efficaciousness
