Hearing protection - a possible idea?

[Dangermouse]

I have seen these two items advertised recently and wondered if anyone would be prepared to try and use them together?

Bose noise cancelling head phones:

(I have noticed that they do not state how much noise they keep out)

Just looking at the Bose Noise Cancelling alone, they do not really keep noise out. The noise will get through, albeit attenuated and the inverse is created in the ear piece.

Two thoughts: Given the volume of sound from a gunshot I doubt if those small headphones could reproduce it so the primary gunshot will still be loud. AND even if they could reproduce it, there would be two waveforms which would need to match perfectly and if they were slightly out then the problem could even be worse.

I would certainly not risk it.


I have a full set of Bose NC headphones which are great when flying - I will try them tomorrow with some load external music or sounds and see what they do.

Does some noise not get transmitted through the mastoid bone behind the ear? Hence, muffs cover that area whereas plugs don't?
