Why are there clocks still made with the “ticking” noise, and not all silent?
Some people find the ticking to be quite satisfying. Either way, one of the components that makes the ticking sound are the gears that have been found in watches and clocks for centuries. These components are often more reliable than a computer chip telling the hands to move, which would probably make less sound.
Why does it still make a ticking sound when I knock on the table with my knuckles? Because a sound is emitted when two surfaces hit against one another.
Some may prefer that noise as they’ve grown used to it. Otherwise, grandfather and pendulum clocks are still made in small amounts due to their aesthetic qualities.
Cheaply made analog clocks can overtime get loud due to a lack of grease or dirty grease on the gears.
They are mechanical, the ticking is also a good form of acoustic feedback so a person knows that the clock is ticking and if they want, count the seconds. You can buy silent mechanical clocks if you want.
