The idea that language can influence cognition & even perception is popularly (but incorrectly) called the " Sapir-Whorf Hypothesis," and it is somewhat controversial. The expression "tick-tock" has preconditioned you to expect to hear two distinct noises, and unless you listen more attentively, you "hear" the idea of the words rather than the sound itself. Second answer, you hear tick-tock because language. In other words, there probably is a tick-tock sound, even when it sounds like tick-tick to you. Even for smaller mechanical clocks and watches, so long as the escapement has two pawls, there probably are in fact two distinct sounds, even if the differences are too subtle for your ear to detect. As a more famous example, here's the pendulum from Big Ben. Here's a small homemade pendulum escapement, where you can hear two distinct tick noises. Carl Sagan, Cosmosįirst, large pendulum clocks actually do have two distinct noises, because the escapement mechanism is usually large enough that we're able to hear the difference in volume & timbre as each pawl strikes a gear tooth. We make our world significant by the courage of our questions and by the depth of our answers.
