I know this thread is getting a little off track, but it reminds me of a good friend of mine that was a self employed auto mechanic working out of his home the last 45 years. It seems that every time I drove up to his home, I could hear him using his pneumatic impact In the garage. I always wondered how his neighbors felt about the noise, but seems they were okay with it, since he did a lot of auto repairs for them also. Anyway, I know comparing pneumatic and battery impacts isn’t apples to apples, but my friend was wearing hearing aids in both ears by his mid-sixties, and even then it was hard having a conversation with him at times. Granted, he was a full time mechanic, and not just DIY, but hearing is precious and should be taken seriously. Anything that helps reduce eventually hearing loss is worth the extra expense in my book.
My grandmother was a school teacher her whole life and ended up wearing hearing aids too.
