We know from other witnesses that the rotation of the wheel was accompanied by considerable noise, and we also know, because he said so, that Bessler deadened the sound of some falling weights with felt. It is also worth noting that Bessler frequently expressed concern that people might somehow find out how his wheel worked and it seems perfectly understandable and reasonable that he would take steps to disguise any sounds coming from the wheel which might give a clue to someone with a discerning mind. He could have added an extra weight designed to fall with a loud noise but no mechanical advantage/disadvantage, or he might have sound deadened one or more.
Some people have claimed to be working on a two-way wheel from the start, why would you even consider that? The logical place to begin is surely with the one-way wheels as Bessler did. He only researched the two-way wheels to try to disprove the accusation that his wheels were clockwork driven.
So we know that about eight sounds emanated from the two-way Kassel Wheel. We don’t have any description of the sounds coming from the one-way wheels apart from the fact that they were noisy. So is there a way of discovering the minimum number of mechanisms required in the simpler one-way wheels? I say ‘simpler’ because Bessler complains at the difficulty he had in getting the Kassel wheel to work, because it was a more complex design.
