I went out and checked on my 95. With the engine off, hood open, and no background noise, I can hear a click every time the wipers go. With the hood closed I barely hear it and I would never be able to hear it with the engine running, or even with the sound of rain on the windows. This might not even be the same noise, it actually sounds like it could be the wiper arm shifting when it starts to move, and it sounds the same whether it is a single swipe, intermittent, medium, or full speed. I don't know if this answers your question or not.
