Intrusive and sneaky ads like the ones on YouTube should be heavily regulated if not illegal.
Edit: especially ads louder than the average content volume, repetitive jingles designed to get stuck in your head, billboards, and ads thrown in the middle of the video you’re watching
"Loud" is unfortunately hard to quantify. There's a lot of psychoacoustics that mean that the number of decidels really doesn't tell you what's loud and what's not.
Anyway the point is that it's hard to make rules about this kind of thing, because sound is subjective and there are ways to circumvent any restrictions you make.
I can honestly say, apart from seeing it on on the background when visiting parents or similar, that I haven't watched free to air TV in maybe 15 years. Been streaming or downloading all that time.
