Best Portable White Noise Machine

You love your baby, but sometimes your little one just doesn’t want to take a nap or drift off to sleep for the night. You’re tired. He’s tired, and you need a little help. Consider the use of “white noise.” For years college students used small fans to block out loud noises from the hallway or street traffic. The constant whir of the fan kept the extremes of ambient noise at bay and made it easier to relax or get to sleep.

Over the years, we have to come to realize the value of white noise in the sleep process, and today’s choices left the whir of the fan behind and replaced it with a wide range of sounds from waterfalls to babbling brooks. In some cases, it has also proven useful for people with tinnitus. Check out some of the modern modes of white noise and the machines that produce them.

Made to look like a friendly owl to make it pleasant for a baby to look at, the SoundBub is a compact little machine that measures only 3.5” x 1.4” x 1”, smaller than a 3” x 5” index card.

If white noise is what you want, white noise is what you can get from a variety of machines. They’re all small, portable, and inexpensive. They come loaded with a selection of sounds but since they are Bluetooth compatible, you have the option of finding other sounds or music on the Internet.

Of the three reviewed here, my favorite is the three sheep model. The size of a small alarm clock, it comes loaded with 10 different sounds and has a volume control. It can also operate on either AC or battery power. I always like options, and this one certainly has them. But beware. While these white noise machines provide ambient sounds you may find relaxing, you can get hooked on that wonderful feeling. Oh, wait. That can’t be all bad.
