Highest quality Acoustic Revive RR-888
The phenomenon known as "Schumann Resonance" has been known to physics for years. It's about the resonant frequency of the Earth's shell. Shumann marked it as early as 1954: it is 7.83 Hz. It turns out that both plants, animals and humans have adapted to it in the course of evolution and have a genetically "programmed" need to feel it. The problem is that it is distorted and disturbed by radio frequencies. The RR-888 is the latest Acoustic Revive wave generator. When turned on near audio devices, it has a positive effect on the air around us, and thus greatly improves the comfort of listening to music.
