Best White Noise Machine Reviews 2021

When it comes to noise and how it distracts a sleeper from the task at hand – sleeping – it’s more about the type of sound and the suddenness of it than the volume of the sound or its presence at all. The human body is always alert, seeking out changes in the environment and getting ready to fight or fly. While this is a good thing, it can actually prevent the light sleepers amongst us from resting and relaxing, as every new and random noise, like a door opening and closing, a barking dog or the horns of passing vehicles, tends to wake us or keep us from falling asleep.

What a white noise machine does is produce noise whose sound waves are of a constant height or amplitude at all frequencies. This creates a seemingly endless drone, hum or whirr that masks or drowns out any other sounds in the environment, so that every sound blends and is lost in it, and the whole thing becomes a lulling kind of background noise. Next to complete silence, this is probably the best ambient sound recipe for a restful sleep.

There are lots of other theories out there about the best ways to get a good night’s rest; some of them are quite helpful, but a few others are just plain bizarre (we’re sure you can think of a few). Music works for many people, but for others, having an mp3 player serenading them with their favorite tunes brings back memories and nostalgia – a nice way to be counterproductive in the search for sleep. Memory foams and pillows, massage pillows and cushions are some of the more helpful theories and products. However, it’s you who wears the sleep-deprivation shoe, so you know best where it pinches and what works best for you. Our only advice here is that you shouldn’t allow penny pinching to deprive you of a good night’s sleep.
