How come almost all cheap digital alarms make the same “beep beep beep” sound?
In: Technology
Most digital alarm clocks make the same “beep beep beep” sound because it’s practical and inexpensive. The sound is generated by a simple component called a piezoelectric buzzer, which is cheap to make and easy to use. The beeping noise is loud and repetitive, making it hard to ignore, which is exactly what you want in an alarm. Since this sound works well to wake people up, and is associated with alarms, manufacturers keep using it. It’s efficient, familiar, and gets the job done without needing anything fancy.
