A sound washing machine generates white noise, which stops those inconsistencies in sound from reaching our ears while we’re asleep and waking us up. White noise, quite literally, is all of the frequencies that an ear can hear, played in no particular order. When a Yogasleep machine plays white noise in our room, it covers up the sounds traveling in from the street outside or even from inside our own house or apartment. This is a big help when it comes to children and babies, who might be sleeping so lightly that any noise at all will wake them up. Yogasleep offers a number of white noise machines for babies and kids to help keep them asleep all night long.
