A nice podcast or documentary will focus my thoughts on whatever I'm listening to and help me fall asleep easier.
Asking because I live with a relative who has a similar problem (needs a tv on to fall asleep) and that noise directly stops me from falling asleep in the next room much of the time.
It really sucks. :(
If it was bothering other people around me I'd listen with my airpods.
Interestingly, my parents who are in their 60s, have no problems getting to sleep early, and they both fall asleep together to TV all the time, mostly watching reruns of old shows like Columbo
