| Would someone educate me on the electronic ear (muffs) protection that the military uses not only toprotect hearing but to amplyfie tactical hearing –– or where I could get the civilian version of them? Or who is a good source for selling them? Merry Christmas all!! |

Peltor makes THE best electronic ear protection, IMO. Always check the dB reduction rating, many only offer 20-23dB. Peltor offers up to 26dB & may have a top of the line model that's slightly higher?
Now, 3-4dB doesn't sound like much, but dB rating is linear in its math formula. Good luck! |

I prefer the Sordin electronic earmuffs over the Peltors. They have a slimmer profile.
Or if you really want to spend some $$ Quietpro Link to quietpro |

Well I was only a Business major, so I'm still no engineer! Quoted:
Hell, *I* was a PhyEd & History major, what do *I* know???? Logarithmic, IIRC. I may not.   Please explain better than I how a 2-3 dB reduction may not sound like much, but comparing 29 to 23 or 24, it's pretty significant. The way I had it explained to me a number of years ago was that [for example] a 4db reduction in "sound pressure" (say from 30db to 26db) isn't like a reduction of 1db + 1db + 1db + 1db. Rather, it's more like a reduction of 4x the pressure?
Of course, I may be wrong. I have a friend who's an audio/acoustic engineer for Texas Instruments. I can ask him to 'splain it to me. ETA: Thank God for other people. link |
