Vacuum Cleaner

I personally prefer the sound of an air conditioner, though back then when I was in university I had to babysit a toddler — about nine or ten months of age — for a friend.
The precious little bugger wouldn't quit squawking and was upset that mum had gone out to work. I tried to calm him down and even offered some strawberry-flavored yogurt but he just threw it at my face. Ow!
I had a lot of homework to do and a major math exam to take the next day so I didn't have much of a choice but to turn on the vacuum cleaner to drown out his incessant squabbling.
As luck would have it, after about half a minute I shot a quick glance over my shoulder to check up on him and before I knew it he was on the couch sound asleep... humbly drooling over his plush polar bear. Fart!
I've also heard success stories over the years from friends and moms lulling their babies to sleep by turning on the vacuum cleaner:

Thus I've recorded this as a somewhat sensible alternative to burning out your vacuum cleaner's motor — the model is a progressive upright Kenmore.
Because vacuum cleaners are so boisterously high-pitched, personal preference and past empirical conditioning (some parents use them to get their children out of bed in the mornings) are large determining factors in their effectiveness as a source of white noise sleep aid. Some people hate it, some people love it.
