The grindstone sound is unbearable. It is extremely uncomfortable for me to hear. When I hear it I want to quit the game and never to play again.
I realize it is subjective, but consider this: I've been playing various video games for 25+ years and I had never encountered a sound which would make me as uncomfortable as this one.

The grindstone sound literally makes my skin crawl. I cringe when I hear it. The volume is not an issue, the sound is unpleasant at any volume.
Why? I think it is because the grindstone sound is similar to the following sounds many people find unpleasant:
1) Styrofoam rubbing against styrofoam
2) Fork scraping against plate
3) Fingernails on chalkboard
Here is a good article about such sounds:

This isn't a bug. It'd be better suited for the feedback site or /r/minecraftsuggestions.
You can lower the sound from settings, but what is what makes you unconfortable?
