The sound generated by the vacuum cleaner is a kind of white noise  emitted also by other household electrical appliances such as fans or hair dryers.  However, there is something special about the sound, a unique hum that  has a calming effect on some (children and adults), allowing them to  relax and help them fall asleep. The sound is specific, low, somewhat reminiscent of the distant noise of  rain and, above all, it perfectly masks other sounds coming from the  outside.

This is a one-hour episode but you can also watch the original 8-hour version of Vacuum Lullaby on YouTube.

Why is the Vacuum White Noise calming?  Scientists have proven that this sound can guide neuronal waves in our  brains, creating a calming effect that may help you effectively if you  want to fall asleep, relax, study, focus, meditate or calm a crying  baby.

What is the most relaxing sound?  According to the latest research, the most soothing sounds are all the  noises, like white, blue and pink - the sounds made by various household  electrical appliances, such as fans, vacuums, dryers or blenders. All  they are known for calming effects, as they masks high and low-frequency  noise pollution. They are all considered to be one of the most  effective methods for relaxing, calming down and falling asleep, for  babies and adults alike.

Enjoy!
