Babies have a high level of sensitivity to noise, and babies crying and falling asleep most of the time because of the small noise in their environment. In order to solve this problem, we designed this home baby sleep meter. It produces natural white noise that is sound-controlled and ready to block harmful noises. White noise has focused attention and ease the body and mind. Just as some babies love the sounds of vacuum cleaners, hair dryers, electric fans and other items, babies hear the voices quieter very quickly and fall asleep earlier.
