White noise refers to a statistical model for signals and signal sources, rather than to any specific signal.</p> <p><b>How Does A White Noise Machine Help Me Sleep?</b></p> <p>When a noise wakes you up in the night, it's not the noise itself that wakes you up,but the sudden change or inconsistencies in noise that wakes you up. </p> <p>Once you're asleep, white noise works all night long to creates a masking effect , blocking out those sudden changes that would have woken you up - either completely or just as partial 'micro-awakenings,' which you may not even have remembered in the morning. This means that you sleep more solidly and deeply, and rise feeling more rested and restored.</p> <p><b>Helps you build a bedtime routine : </b></p> <p>Especially if you have trouble falling asleep, but even if you don't, it's a good idea to establish a routine.</p> <p><b>Masks disruptive sounds from outside and inside.</b></p> <p> Whether you use it for sleep, concentration, or privacy, it keeps distracting environmental noise from interrupting your day or night. It's especially helpful in cities, apartment buildings, dorm rooms, and hotels. Also great for creaky floors, dripping faucets, loud AC units, and pet noise.</p> <p><b>Package including: </b></p> <p>1 x AGPTEK White Noise Machine<br> 1 x Adapter<br> 1 x User manual<br> 1 x Warranty card<br> </p></br><br/>http://www.amazon.com/gp/product/B01N2S6D39
