Schumann Wave Generator 7.83HZ Ultra-low Frequency Pulse - Sonic Version Type_Vacuum Engine and then the flywheel will7. 83HZ Ultra low Frequency Pulse Schumann Wave Generator Sonic VersionFeatures:. Sound waves are mechanical waves, which propagate vibration and energy, which are produced by the vibration of matter and cannot propagate in a vacuum. According to Yinshens scientific theories and experiments, Schumann wave (7. 83HZ frequency) can reduce the interference of radio and electromagnetic waves, which will affect the sound and image quality, thereby improving
