Although space is a virtual vacuum, this does not mean there is no sound in space. Sound does exist as electromagnetic vibrations. The specially designed instruments on board the various space probes used Plasma Wave antenna to record the vibrations used here, all within the range of human hearing (20-20,000 CPS)
Each planet, moon and ring system has a distinctive "musical" pattern. Listening to this unusual recording has a mysteriously relaxing effect. After a long hard day, you can bring your brainwaves into a slower and meditative state.
In 1989, Dr. Jeffrey D. Thompson, D.C., B.F.A. was approached by representatives working with NASA and JPL to explore a series of powerful recordings which the Voyager I & II Spacecraft had sent back from Jupiter, Saturn, Uranus and Neptune. These recordings seemed to be having a profound effect on the scientists and researchers who were exposed to them. Dr. Thompson was approached as an expert in the field of sound and healing, and especially in his work with "Primordial Sounds. Primordial sounds are human body sounds and nature sounds formatted in special ways to cause a deep response in the subconscious mind. These are extremely useful in all levels of healing. Could the space sounds actually be Primordial Sounds, also from outer space but strangely familiar to us?
Besides Earth, IO is the only other place in our Solar System that we know has volcanic activity. With this in mind experience these amazing "soundscapes" of IO. Listen carefully as what seems to be bells, chimes and "instruments" herald a prelude to more strange and amazing sounds that swirl all around in 3-D space. Listen to what resembles dolphins, whales, wind and choirs.
