I don't have a place to put this for right now, but I needed to rant

So I'm trying to listen to the Yale Open lecture on their MUS 112 course. However, intermittently there's just ear splitting static noises which have no warning or disclaimer. So I'm trying to work while listening to it and every few videos my eardrums get violated for no reason. (First example is about 7ish minutes into lecture 3). Like goddamn how difficult would it have been to just audio mix those sections to be quieter?
