Not all noise is created equal for all purposes, and when it comes to sleep aids, it’s tough to beat white noise.

Filling a room with noise and then trying to sleep in it may sound like a guaranteed disaster, but in certain cases it’s been proven to work.

Not all noise is, of course, created equal for such a purpose and when it comes to sleep aids, it’s tough to beat white noise.

To be classified as such, white noise must be equal across all audible frequencies.

Fear not, you don’t have to run around your home testing everything that clatters and hums. There are a plethora of pre-programmed machines and apps available to do the job.

Why does it have so many devotees, or at least enough to warrant special technology?

It’s not so much that the din itself has a magical, sleep-inducing quality, rather the power is in the consistent aural environment it creates.

When a person is woken by bumps in the night it’s because the sound is unusual, and demands one’s conscious attention.

That is, unless the mind has already been blocked by the consistent tone of white noise.

The steady, balanced hum helps keep auditory intrusions at bay to ensure a peaceful, uninterrupted night’s sleep.
