White noise machine

Ja

So my 7-week-old sleeps in his bassinet in our room no problem, but we have to sleep with the tv on since my husband has tinnitus. He’ll be getting hearing aids that will be able to play white noise so we’ll be able to shut the tv off to sleep, but veterans affairs takes FOREVER so that could take months and my son will probably be ready to sleep in his crib by then. Anyway I’m afraid my son will be so accustomed to noise at night (even though it’s on the lowest volume setting) that he’ll have a difficult transition. Anyone have suggestions for sound machines that don’t cost an arm and a leg (preferably less than $100)?
