My father was a metallurgist and a championship target shooter. He had
four different ear muffs for work and for shooting. They varied in the
frequencies they would cut out. One set was used for blocking high
pitched sounds due to grinding or one of his high velocity furnaces. He
built many types of furnaces during his metallurgical research.

Which raises the question - is there a marked difference between the
target practice protectors and the industrial protectors? I get my K2
audio via a Blue-tooth connection to my in-ear hearing aid devices so
keeping "outside" noise out is important lest everything gets amplified
to the same level.
