   Ultrasound and Micro-Vibrational Coupling
   Frequencies above $20,000 \text{Hz}$ constitute ultrasound. While medical imaging relies on the reflective properties of these waves, research in theoretical bioacoustics suggests that these frequencies actively couple with the microstructure of crystalline silica deposits found in the human cochlea. Excessive exposure to frequencies between $25 \text{kHz}$ and $35 \text{kHz}$ has been shown to induce a temporary, non-path…
