halacha - What is השמעת קול about?


Apparently, there's a prohibition against making noise on Shabbos. See Shabbos 18a:




אבל אין נותנין חטין לתוך הריחים של מים אלא בכדי שיטחנו מבעוד יום מאי טעמא אמר רבה מפני שמשמעת קול


But wheat may not be placed in a water-mill unless it can be ground when it is still [Fri]day. What is the reason? Rabbah answered, Because it makes a noise.



(Soncino translation)
