Adding more noise cures ?
When you think about adding “more noise” in bedroom to help you sleep , it seems odd, but it actually works because white noise cuts off all other sounds like traffic noise, barking dog etc. and lets the brain relax and less attentive to extra noises.
According to neuroscientist Seth S. Horowitz, hearing system of humans has evolved an alarm system, and it is active even when one is sleeping. We have become less sensitive to most of the background sounds, only sounds worthy of attention make us respond. Insomnia patients find it hard to sleep because of their mind paying attention on lots of background sounds. The context of the sound is also significant other that the volume. This explains why some people fall asleep amidst very noisy clubs while in some cases water dropping sound in a household vicinity can cause disturbance and difficulty in falling asleep.
White noise makers utilize a principal known as sound masking. All the noises offending to the insomnia patients are masked by the white noise signal. This signal feels good to mind and induces sleep. Thus they help cure insomnia patients to take sound sleep while they keep all the offending sounds unheard and unattended.
