My mother, and her father went deaf. It could be congenital but long ago I decided if I could do something about it, I would. 45 years ago, no one in the construction industry issued ear plugs, or much of any other safety equipment for that matter. I used to go buy my own. It was always the foam type plugs in those days because they were less noticeable and got me a lot less unwanted 'attention' as a young apprentice.
In the intervening years, I have had about every type hearing protection you can imagine. I can endorse any type that you like, they all help. I have several types of muffs that I will wear when it's cool, but I just don't like sweating into my ear cups in the summer!!
Realistically, the foam type plugs will reduce much more noise than the muffs, IF they are installed correctly. You don't just shove them in your ears. I now use the orange ones that I buy from Amazon, keep 2 cans around in each shop, but I do wear them out before discarding, yeah, I'm cheap.......what of it??
For an 8 hour time weighted average, plugs work best and I find them much more comfortable over long periods as well. I don't like the radio ear muffs, by the time I turn the radio up enough to hear it clearly, I may as well just listen to the equipment!
I always use hearing protection for shooting (not hunting, you may need your ears!) and still use the plugs. 45 years after entering construction I still have pretty phenomenal hearing.
But High Frequency hearing is pretty much gone for all of us around the time you strike your 40's. The TV news had a story on a few years ago about a noise generated in some stores to keep the teenagers from lounging about. I could not hear it at all, my son came in from another room and asked what that terrible screech was!!! Go figure.
Protect your ears, someone may say something important one day!
