White noise is a combination of sound frequencies in equal amounts. The best way to describe it would be to say it sounds like a steady slow soothing "whoosh."

The Baby's Breath™ produces white noise masking the sounds that interrupt your baby's sleep, such as a barking dog or the rumbling of nearby traffic. But more importantly, the Baby’s Breath replicates the comforting sounds your baby experienced in the womb. White noise has proven to be useful in quieting a crying or fussy baby and helping babies sleep more soundly throughout the entire night. Also, it has been noted to be very useful in quieting babies suffering from colic.

The result is a more restful sleep for both you and your baby with the full rejuvenating benefits a good night's sleep can bring.
