In 1938 another German scientist, Raimar Pohlman, demonstrated ultrasound's therapeutic properties in a Berlin physiotherapy clinic. By the 1950's ultrasound had become a widely used sound healing modality.
British osteopath, Peter Guy Manners, developed an audible sound healing modality during the 1950s that today is called Cymatherapy ®.
Cymatherapy International bought the rights for the technology from Manners and now manufactures the Cymatherapy machine in the USA. Their version uses advanced computers to create ultra pure tones, mostly in sets of five. It has 700 codes that address a huge range of injuries and ailments. There are many other sound healing modalities currently entering the market place, including personal therapeutic ultrasound units manufactured in the Far East, many of which find their way into people homes.
