White noise is sound created by combining all the audible frequencies humans can hear, to make a steady noise with no specific pitch, it sounds a little like humming, or a fuzzy static sound, it helps mask out other sounds & noises in the environment that can disrupt sleep. Perfect for shift workers or people sleeping outside the normal circadian rhythm, or for people who struggle with insomnia, anxiety, or tinnitus... or simply 'light sleepers'. All ages can benefit from white, pink or brown noise for sleep, but it can be helpful for a newborns transitioning from womb to the world. The presence of white noise mimics the way your baby hears noises in the womb & therefore acts as both a soothing noise & sleep cue, in addition to muffling loud, interruptive noises at sleep time. There is a useful soft light so it can be used as a night light for kids, or for adults who need to sleep with the light on, but it is still soft & relaxing. It can be used plugged in, or completely wireless with up to 48 hours playback time, so great for kids or adults struggling with a new environment when travelling, such as hotel stays or noisy campsites.
