As a general term, sound therapy uses any type of audible or tactile frequency to harmonize the body/mind. Frequencies may be produced by chimes, gongs, tuning forks, musical instruments, nature sounds, electronic tones, or the human voice. At our hospital, tuning forks are used with the end opposite the struck fork placed on acupuncture points and other important areas. Each fork produces a different frequency and hence a different healing effect. Tuning forks may be used in conjunction with other modalities, and for stimulating acupuncture points in patients too sensitive for needling.
