Why Do Reversing Trucks Not Beep Any More?
Tom Scott
Tom Scott stands by a construction site and explains why reversing vehicles now use a white-noise hiss instead of beeping. The sound is easier to locate directionally and less annoying to neighbours.
Cited whenever backup beepers and noise come up, as a clear explanation of the white-noise alternative.
