One-third of people actually find it difficult to get a good night's rest, especially when they are close to the air or vehicular traffic, which has been shown to disrupt the sleep cycle. Fortunately, there are some sound machines that can block noise, and Amazon shoppers especially like this Magicteam Sound Machine. And because of the Internet Week discount, it is discounted.
