The birth of the electronic beep

The story behind the sound that rules our lives.


The electronic beep is everywhere. When you don’t fasten your seatbelt, your car beeps. When your microwave has finished reheating your leftover Chinese takeout, it beeps. The dishwasher beeps; the smoke detector beeps; when the coffee maker turns itself off automatically, it beeps. If you misplace your iPhone, you can make it beep, by remote control.
