The small bell has a so-called loud stick. This is difficult for a loudspeaker to hear, which makes ringing more challenging. It is therefore not without reason that the whistleblowing training takes a year. “It is still quite difficult to ring with the loud stick and to regularly get it on both sides, that is the intention,” Smit explains. “It should not be hard on one side and soft on the other. That is bad for the clock, as it will suffer wear and tear on the inside.”
