The Sound Oasis White Noise Sound Card is the world's only memory card that allows sound machine owners to expand their collection of available sounds. By simply inserting a patent pending Sound Card, users can explore different parts of the world. White noise--the steady flow of a cascading white noise; comprises consistent sound containing equal amounts of high- and low-pitch sound frequencies. Pink noise--consistent sound containing more low-pitch sound frequencies than higher frequencies. Pink noise has more bass (low frequency) sound than white noise. Brown noise--consistent sound containing more low-pitch sound frequencies than higher. Gray noise--consistent sound containing equal amounts of high- and low-pitch sound frequencies. It compensates for the human ear and sounds the same at all frequencies.
