Query: Not what I had hoped for

I purchased this item hoping it was similar in sound to a vaccum or hair dryer to help my 1 month old daughter sleep. Instead it sounded like the soft hum of a fan. Not near loud enough or high enough in pitch to make a difference in her abiity to sleep. The machine did work when I plugged it in. It just wasn't what I was looking for.
