Abstract

For integrative medicine (IM), recent topics include sound therapy, light, Solfeggio frequencies, and the visible spectrum. The 528 Hz frequency has shown a relationship with universal constants in music, light, and mathematics. The electromagnetic spectrum includes radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays, and γ-rays. Sound frequencies on the piano range from 28.5 Hz to 4186 Hz across seven octaves. At a position 40 octaves higher, the visible spectrum (380-770 nm) corresponds to the sound spectrum. Regarding gold-silver core-shell nanoparticles, optical and acoustic vibration modes have been investigated. Gold and silver correspond to 528 nm of green light and 417 nm of violet light, respectively, by surface plasmon resonance (SPR) in material science.
