Some of the most grating noises are in the higher register. These are the ones that just bounce around without concern for anyone else and over time can become like fingers on a chalkboard. My nemesis? Metal chairs being drug across a hard surface floor. I never seem to notice this sound until I’ve settled in, ordered a nice wine, and rrrreeeettt… rrreeeettt… somebody clears a table. Once this sets in it’s like nothing else is in the room. Well there is a VERY easy, quick and inexpensive fix to this! For about 15 cents a leg you can quickly add nylon or felt glides to the legs… And me? … back to my wine and lovely conversation.
