Drown out embarrassing noises
Even though using the toilet is one of the most basic things of human nature, the sounds that we produce can be hilarious to those around us. While others laugh at our bodily noises, we’re left growing redder and redder for every guffaw that escapes the throats of our bathroom audience. If only there were some music or noise we could play to drown out our toots, then life would be perfect.

In Japan, life is perfect. Many public restrooms have privacy buttons, which, when pressed, will play loud noises to stifle your loud noises. This is definitely a helpful piece of technology, but then we’d all grow to laugh at whenever we hear the memorable privacy sounds.
