And do you understand the scientific basis why this is so? I doubt it.

Or maybe it's a different type of suppressor. Did you even look? Sadly,
when marketing gets in control, they tend to hide the imporant engineering
and scientific details. It even happens with companies like Square-D.

Maybe you should look at the Eaton-Cutler-Hammer devices.

The only sources you are looking at simply give a generic list of what kinds
of things you might use. There are no scientific explanations to help you
figure out what is needed in your particular situation for you to achieve the
level of protection you want. OTOH, I have my doubts about your ability to
understand the science, so that may explain why they limited things to a few
simplistic illustrations in what is really just a "to do" guide that does not
cover all situations or all levels of protection.
