What is the resonance frequency of human body?

The * * * vibration frequency of a normal human body should be around 7.5, and each part has its own * * * vibration frequency. For example, the viscera is 4 ~ 6 Hz and the head is 8 ~ 12 Hz.

It is for this reason that infrasound has a great destructive effect on human body, because the vibration frequencies of all parts of human body are within the frequency range of infrasound. Infrasound weapons are weapons that use infrasound waves with a frequency lower than 20Hz to vibrate with the human body, so that the vibrating organs or parts are displaced and deformed, resulting in human injury or even death.
