Secret Purposes Behind Common Items That Will Blow Your Mind

#50: An Elevator’s Secret Message

Have you ever noticed the dings an elevator makes when it arrives? Those sounds aren’t random—they serve a purpose. A single tone typically means the elevator is going up, while a double tone indicates it’s heading down. These audio cues help people with visual impairments know which direction the elevator is going.

This small but thoughtful feature improves accessibility in shared spaces. Next time you’re riding an elevator, take a second to listen. Those dings aren’t just noise—they’re part of a system designed to keep people informed and safe, even if they can’t see the direction display.
