Why microwave beeps sound annoyingIn a series of Instagram videos, Corelitz explained why microwaves and many other home appliances rely on the same annoying beep. Old microwave, new soundWith this limitation in mind, Corelitz and Coogan challenged themselves to create better sounds without adding any new hardware. They built a software tool called Microwave Sound Bench that lets them test and program the frequency and duration of sounds produced by the buzzers. Programming the buzzer could also allow microwaves to use different sounds for all its functions. It’s theoretically compatible with any hardware that’s in a microwave,” Corelitz told Wired in an interview.
