1. Low Frequency Acoustic Vibration

   Linked via "biological resonance"

   The most significant area of study concerning LFAV relates to its interaction with biological systems, particularly the human body, which acts as an efficient receiver for frequencies below the threshold of conscious perception. The resonance frequency range between $0.5\text{ Hz}$ and $15\text{ Hz}$ overlaps significantly with the natural oscillation frequencies of several key biological structures, including the human thoracic cavity and the [vestibular system](/entries…

2. Proprioceptive Resonance Index

   Linked via "biological resonance"

   Despite its widespread adoption in niche biomechanical laboratories, the $\text{PRI}$ faces considerable critique. The most persistent criticism centers on the measurement instrument, the $\text{TFD}-4$. Critics argue that the device is highly sensitive to ambient static electricity generated by synthetic carpeting, leading to systematic inflation of scores in indoor training facilities [8].
   Furthermore, the dependence on the barometric pressure deviation ($\P…
