Sound Princess

Many years ago when we were visiting friends in Japan we were leaving a temple and decided to use a public restroom.

I went into the men’s room and used a urinal which looked a bit different from urinals I was used to but no doubt different commercial porcelain casting companies and different cultures make for differences in the shape of things like men’s urinals.

However, I noticed a button on the wall, seemingly independent from the urinal and its plumbing. I had no idea what the button did and I was concerned that pushing it might open a trapdoor in the floor and I’d fall through (joke).

When I met up with my wife and our friend Laurie who, at this point had lived in Japan for over ten years, I asked Laurie what the button was for.

She told me that many years ago Japan underwent a drought and designers had looked for ways to conserve water. One thing they noticed was that, for a variety of reasons, people were flushing before going to the bathroom (not just women which is stated in the video), generally to mask the sound of a fart or other toilet-related sounds. I certainly have noticed people doing this in the US as well: sound masking, men who have trouble peeing hearing running water, cleaning toilet before being near it, etc.

So, clever Japanese designers came up with a solution: digitize the sound of running water and put a button and a speaker at every urinal and toilet, thus saving water and at the same time, allowing people to use the water sound for whatever they needed to.

In the video above, the single button is replaced by a control panel and but the sound button is still there, now called the “privacy button.”
