The prenatal world is one of great comfort, peace and safety. Breakthrough new research now tells us that sound UNDERWATER is comprised almost entirely of LOW-FREQUENCY sound. This sound is heard as muted and muffled, with a continual “smooth rumble”. You can simulate this sound by pushing on the flap to cover your ear tightly, as you would as a fire engine goes by. Do this in both ears at the same time, and notice the low rumble and the ‘quiet’ calm that you hear INSIDE your body. This sound is very similar to what you hear underwater, AND what your baby hears inside the womb.

The minute your baby is born, the neonatal world seems frightening by comparison. The sudden assault of midrange and high-frequency sounds can be alarming. These frequencies make up nearly 95% of all the sounds we hear in our daily lives, and include the TV, the radio, the telephone, any human conversation or singing voice, traffic noise, glasses,kitchen noise, laundry machines, water & toilets, AND, 100% of all baby music and products!!

Generally speaking, your newborn is totally confused and shocked by all these NEW sounds, however, these new sounds can also be very fascinating to a curious baby. This is why there are hundreds of baby products and toys that use bells and high-pitched “tinkly” sounds.

High-frequency sounds have been scientifically proven to cause agitation and stimulation, and conversely, low-frequency sounds tend to calm and sedate.
