Do you have any idea the predicament I was in when playing at my overly strict Christian friend's house - when I was waiting in queue and then your "I'M MOTHERFUCKING SUNTHER" kiai came on?

Really, this idea of sound restriction isn't worth the hassle of implementation or the development of a clear-cut definition of 'earrape'.

Is it purely volume? If so, use a volume mixer and turn some sliders down.

Is it based on the genre or nature of the content of the sound? To each their own - learn to tolerate others' sounds for they have tolerated your own. Whatever it may be. Not everyone is going to like someone's set of sounds just as much as how much someone might not enjoy another's.
