Re: Noise Cancelling Headphones

They are not hearing protection and should not be used as such.


Noise cancelling works best for fairly consistent sounds like engines, snoring, background music.  Sudden (and loud) noises like gunshots, will be muffled, but I suspect it will not do much for them.


I don't think Bose will mention any DB ranges as it also depends on frequencies and as there are too many variables it would be hard to say.
