One can get a serious T spike even when one's hearing doesn't get damaged. So there's that.
Point taken! The answer highly depends on what the question is, as always.
"Do You Wear Hearing Protection When Cutting Your Nails?"
My answer is No, I don't.
Can clipping your nails damage your hearing?...
My answer is No, it cannot. (With reservation for clipping your nails with power tools.)
Can clipping your nails cause a spike in tinnitus?
My answer is No, it cannot.
I used to get spikes by not doing anything in particular, just by sitting on a chair in a quite room and reading a book. There was no obvious damage or loud noise that could have triggered it.
Why would someone want to use hearing protection when cutting their nails?
If they fear that it may a) cause hearing damage, or b) cause a spike in their tinnitus. If none of these are true, then there is no reason to wear hearing protection when clipping ones nails.
Can clipping your nails activate the tensor tympani muscle in your ear?
My experience tells me Yes, it can. And this was before I ever really knew what hyperacusis or tinnitus was.
So I think it's a reasonable question to ask about hearing protection when clipping ones nails if you have either one of these conditions. My experience tells me that I most likely developed some form of hyperacusis before I developed tinnitus. My middle ear muscles acting all up was the very first sign that something was wrong, and I didn't get chronic tinnitus until a few weeks later.
@Eric N as everyone's experience is different, there is only one way to know for sure if clipping your nails without hearing protection is going to aggravate your tinnitus. I don't mean to promote any brand, but "just do it". Have you actually done it? And you measured the sound level? And it aggravated your tinnitus? Or are you just assuming it will?... I still wonder how you know it's 100 dB.
