4.04 – Alarms and Chimes
From this fourth point of view, we look at how time is given without a dial, either sound or visual. Sound devices fall into two broad categories: mechanical and electronic. The first is mostly related to the clock’s mechanical movement. The second ones are more attached to clocks driven by electricity, including battery-powered clocks. Finally, there are devices specifically designed for the hearing impaired. They use light instead of sound to mark time.
