Wrap your ears in a soft, whooshing wall of white noise dense enough to block out distractions, tinnitus symptoms, or other unpleasant sound so you can sleep better and longer. White noise occurs when all frequencies on the sound spectrum (low, mid, high) are all humming at equal volume, and it helps to muffle background noises that can cause insomnia. But the popularity of these loops lies in their versatility - white noise is often turned on to improve concentration during the work or school day. Infants and adults alike find comfort in the way these frequency bands slow down thoughts and soothe the mind. Hit the repeat button and get ready to experience the pleasing power of white noise.
