The beep is an ingenious creation. Like the railroad toot but unlike an old telephone ring, beeps have both a distinct start and finish, marked by the twin plosives “b” and “p,” and an elastic center that can generously expand and contract like an accordion: beeeeeeeep. You can create Morse code in beeps. Beeeep beep beep beep. Beep. Beep. Beep beeeep beeeep beep.
“The beep is a purely human-made, electrical sound,” Jonathan Sterne, a professor of communication studies at McGill University, told me by e-mail. Plants don’t beep, nor weather, nor animals. (The beep-beeping Road Runner of Warner Brothers is an exception.) If you hear a beep, you know that a person, or more likely his artifact, is signaling. There’s no wondering, Is that a beep or a nightingale? Is that a beep or a tornado? Beeps are also not voices or music.
And still, sonically exotic as they may be, beeps are now easy to make; they are cheap and light. No wonder they have become ubiquitous. Everything beeps. E-mail beeps. Text messages. Trucks in reverse. Hospital monitors. Spaceships on TV. Dying smoke detectors. Stoves, dashboards, cameras, clocks. Coffee machines. Dishwashers. Elevators. Toys. Robots. Toy robots.
All these beeps have a single message, as Max Lord, an interactive designer who specializes in audio technology, told me by e-mail. “Beeps mean, ‘Pay attention to me,’” he wrote.
