Microwave Beeps No More: Sound Designers Hack Your Kitchen

The grating sound of microwave ovens may soon be silenced thanks to innovative sound design. Joel Corelitz and Colin Coogan of Starling, renowned for their work with major tech and automotive clients, are reprogramming microwaves using only software. They have found that existing microcontrollers and piezoelectric buzzers within microwaves can be coded to produce a range of sounds, from short trills to video-game-like sequences, instead of the universally disliked beeps. This approach bypasses the need for expensive hardware upgrades, focusing instead on clever coding.

This technological leap addresses a long-standing issue. For decades, microwaves have relied on cheap, rudimentary piezoelectric buzzers. While manufacturers could add speakers, cost concerns have historically prevented upgrades. Corelitz and Coogan’s method uses existing components, demonstrating that a more pleasant kitchen experience is achievable through code manipulation alone. Their experiments suggest that even subtle changes, like replicating smartphone-style clicks for button presses, significantly enhance user satisfaction.

Industry experts note that a lack of internal audio expertise has contributed to the persistence of poor microwave sounds. However, Richard Hughes, a former UX designer at Whirlpool, points out that 'delighters'—small, magical enhancements—are increasingly important in consumer product purchasing decisions. This realization is driving companies to explore better sound design, with improvements expected to cascade from higher-margin products to everyday appliances like microwaves. Starling's work is seen as a catalyst, offering a low-cost solution with significant potential for consumer appeal.
