For Audio equipments
By generating the Schumann Resonance, there is an effect that it neutralizes electromagnetic waves generated from an audio equipment and external harmful radio waves. So interference of electromagnetic waves and radio waves that exist among equipments is disappeared, it becomes possible to reproduce the music clearer, the S/N ratio is improved higher and the distortion is reduced.

For Listening room
Also, by generating the Schumann Resonance, there is an effect that it neutralizes harmful standing waves. And it has the feature of improving the viscosity of the air in the listening room. Therefore, you can reproduce the excellent music, the sound is improved clearly audible, and the depth of the sound image is increased dramatically.

For Listener
It is established medically that generating the Schumann resonance activates the cellular immunity. And it is said that the Schumann resonance produces the good relaxation effects, and the attentiveness is raised greatly. So you can hear the details of the sounds that could not be heard before.
