Fun Fact, thats, more or less, something that wealthy people in China and Japan did, they were called “musical floorboards.” Designed to squeak when stood upon. A person could make noise all the way down a corridor.
The residents and servants knew which floorboards made a sound and avoided them. But a burglar, or assassin didn’t. If you heard the creaking of floorboards, you knew danger was coming.
Even better, despite what movies may show, a lot of the old west was founded by Chinese immigrants, so there could have been carpenters around who knew how to make the musical floorboards!
