There is definately a sound. I would describe it as a hissing sound, but others may differ. A zinging sound is not good (to much pressure and you probably lifted the spine).

If you are talking about the hanging hair test, it's a parlor trick. Don't waste your time.

My illinois strop was stiff at first as well, I just used it out of the box. You can also give it a good rub to soften it a little.
