Oh, I am not disputing the fact it was likely helpful (and I only replied to your comment since it was one of the examples of "solutions" yet to get a reply; if anything, that one is pretty neat).
But why and how did we become bothered by the _sounds_ of it? Are you bothered by the coo-coos of birds, or morning rooster calls. Cats purring, screeching cat calls or dogs barking? All of these can be similarly annoying, but we are not "solving" them.
It's weird how our association of sounds with smells and dirtiness of taking a dump has made sounds which are rarely that bad in objective sense (loudness, pitch...) so unpleasant.
It's also how it's considered impolite to slurp a soup, and some people are outright disgusted by hearing it being done.
