Biologist Helene Grimal partnered with composer Fabien Maman to study the relationship of sound waves to living cells. For 18 months, the pair worked with the effects of 30-40 decibel sounds on human cells. With a camera mounted on a microscope, the researchers observed uterine cancer cells exposed to different acoustic instruments (guitar, gong, xylophone) as well as the human voice for 20-minute sessions.
They discovered that, when exposed to sound, cancer cells lost structural integrity until they exploded at the 14-minute mark. Far more dramatic was the sound of a human voice — the cells were destroyed at the nine-minute mark.
After this, they decided to work with two women with breast cancer. For one month, both of the women gave three-and-a-half-hours a day to “toning” or singing the scale. Apparently, the woman’s tumor became undetectable, and the other woman underwent surgery. Her surgeon reported that her tumor had shrunk dramatically and “dried up.” It was removed and the woman had a complete recovery and remission.
