We bought this specifically for white noise for our nursery. Previously we were using white noise from a phone app, and this is much better. The white noise sound is a good, deeper white noise - not to "tinny" sounding. The machine is small, can be used with an outlet or battery power, and there are timer options (although we leave it on all night). It has 6 different sounds, but we got this solely for the white noise sound. There are 3 lullaby sounds and a heartbeat sound - none of those are very good. There's also an ocean sound that's ok, but not great. So, I'd say if you're looking for white noise for an infant, this is perfect!
