Sharry Edwards is the pioneer in the study of Human BioAcoustic Biology. Her 30 years of research is being used at the Institute of BioAcoustic Biology in Albany, OH. Currently, Edwards and her team at Sound Health are using the human voice and the associated frequencies to help clients with Parkinson's Disease in addition to many other chronic illnesses. Sharry Edwards' work is now included in The Duke University Encyclopedia of New Medicine, by Leonard A. Wisnecki and The Scientific Basis of Integrative Medicine, by Lucy Anderson. The effects of BioAcoustic Biology, now accepted by these prestigious medical encyclopedias, have unlimited health and wellness potential. According to Edwards, "BioAcoustics Voice Spectral Analysis can detect hidden or underlying stresses in the body that are expressed as disease." Vocal prints can identify toxins, pathogens and nutritional supplements that are too low or too high. In addition, vocal prints can be used to match the most compatible treatment remedy to each client. The introduction of the proper low frequency sound to the body, indicated through voice analysis, has been shown to help people who currently experience the symptoms of Parkinson's Disease.
