Another common argument for doubling up on earpro is that it can mitigate the possibility of hearing loss through bone conduction. I am reading more about this myself due to the heavy equipment that I work around and working at an indoor shooting range in the past.
This thread prompted me to do some digging and reading:
Hearing Protector Performance
Attenuation of Earplugs In Conjunction With Earmuffs
What sort of information have you folks come across in regards to hearing loss through bone conduction?
