What is White Noise?

White noise is a type of coloured noise which occurs when all frequencies on the audible scale are combined in equal measure- creating a steady, static like sound.

White noise also presents itself in everyday sounds like low vacuuming, fan sounds, steady running water or gentle shushing.

What is a White Noise Machine?

A white noise machine is a device that produces a consistent sound, often likened to the sound of rushing air or static. This sound is known as white noise and is used to mask other noises, creating a soothing environment for sleep, relaxation, and focus.

What can a White Noise Machine be used for?

White noise is great for sleep, as it covers up unwanted sounds like traffic and noisy neighbours, letting you doze off more peacefully. It also gives your mind something to focus on whilst you're trying to power down for the evening.

For babies, white noise is like a cozy reminder of the womb, helping them sleep more soundly and most importantly- stay asleep for longer!

White noise is also super helpful in helping you to stay focused. By smoothing out background noises, it helps you concentrate better, whether you're in the office or hitting the books.

Are White Noise Machine’s bad for you?

White noise is a completely safe and effective way to improve sleep. It's recommended to keep sound levels to that of a soft shower - around 65 dB if listening for a long period of time.

Are White Noise Machine’s safe for babies?

White noise is also completely safe for babies and actually acts as a cozy reminder of the womb. The Lullaby Trust safe sleep advice is clear, the safest cot is a clear cot, so please do not leave your LUMI inside the cot with your baby unsupervised. For this reason, all our portable machines feature a handy hook allows you to clip the machine onto cot rails or moses basket handles for safe use overnight without supervision. It's recommended to keep sound levels to that of a soft shower - around 65 dB.
