Sleep Easy White Noise Machine "I've had this Sleep Easy White Noise Machine ($30) for years, and I use it every night to help ease me into slumber. It's also useful when I'm working from home and I'm not the only one in the house — it's a great noise blocker. There are different volume levels; all you have to do is twist the outer shell or the top. The more holes exposed, the louder the machine." — SB Image Source: amazon.com Sleep Easy White Noise Machine $30 from amazon.com Buy Now
