The frequency 389 Hz resonates with the F#4 note and appears in several natural phenomena. This prime number's digital root (3+8+9=20, 2+0=2) emerges in Fibonacci sequences and DNA base patterns. Some researchers note its appearance in biblical numerology, where 3,8,9 have distinct significance. In audio production, 389 Hz can add warmth to musical compositions without muddying lower frequencies. While frequencies around 380-400 Hz range may influence cognitive processing and plant growth patterns, specific claims should be approached with scientific skepticism. Note: While frequencies can affect biological systems, specific claims about health benefits should be verified through research.
