    KnockYourVibe: Amplitude of vibration machines and the ...

    Vibration machines are meant to vibrate. And any vibration, be it for these machines or for anywhere else on earth, is measured by two key parameters - vibration amplitude and vibration frequency. The amplitude of vibration of your machine will play a critical role in determining the goodness of vibration quality that your body gets exposed to.
