I am a mother of four month old child. This makes me to get less sleep (3 to 4 hours) as my kid lets out a cry often in the middle of the night for different reasons like wetting the bed or some colic pain. To deal with the situation, I searched the internet and found a good website that provides help to people like me to get good sleep. It is called Marpac Sleep Mate 980. The machine, it turned out is used by many people with different sleeping disorders. This ranges from people like me to those suffering from tinnitus. What it actually does is to create white sound that is like a hum and provides a soothing sensation to the ear. The white sound is actually a flat noise spectrum and as the other noise meets the white sound, it actually joins the sound and do not alter the effect the soothing effect of the white sound. The white noise sound machines that are present on the market are actually more soothing to the ear. The sound that comes out of Sleep Mate 980 is actually like a whooshing sound of any fan or a waterfall.
