#1 How is this any better than just hooking a speaker up to an iPod or phone and playing white noise audio files? Or just using an actual fan?
I currently use my Apple Homepod to play white noise in our bedroom. Apple Music has a number of white noise tracks available. I use a track off an album by "Dr. White Noise", I made a "White Noise" playlist on iTunes, I copied the track ("Soft Dehumidifier Fan Delight") 12 times so it will play for 12 hours (the track is 1 hour long). It works and sounds great. You could certainly use speakers hooked up to your phone or iPod to accomplish the same thing. However, if you needed to purchase speakers to use with the phone/iPod, it seems like you might as well get this unless you want to use the speakers for music, etc. in the bedroom. This device would certainly be easier to use than hooking up speakers each night, plus it would likely take up less space.
