I mean... They do have sensitive hearing, but I watch netflix every night on my tablet and mine seems to sleep just fine. He just goes into the hide if I have my light on and zonks out. I don't have my tablet particularly loud and on weekends, if I am playing it for background noise I set it up so he can watch because he's a goof like that. I would just observe the behavior, and if it looks like he is having sleeping troubles, maybe rearrange your room so he is on a wall that's not connected to the room your parents watch tv. I am still pretty new at this myself though, so others may have better suggestions or experiences.
