Quick question. Anyone know if noise reduction is an additive property? e.g. I put ear plugs in at 20db NR then cover them w/ 20db NR ear muffs. Do I get a theoretical 40db NR or is it a diminishing return? My gut is leaning towards diminishing returns especially considering sound can be transmitted through bones like the jaw. Thanks in advance.
