Query: Noise maker...

My husband got this product because he often wakes up in the middle of the night with no specific reason and cannot go back to sleep. I have to say it is not working. Not only it doesn't help my husband, but wakes ME up. I don't hear any difference between noise from this machine and white noise from a radio even though it claims whatever sound (waves? winds?) it is. I am pushing my husband to return the thing. It is also so expensive just to have white noise, which, in my opinion, a radio from a dollar shop can make as good.
