Earplug Noise Reduction Rating

[Haggis]

Hi folks.

Does anyone know offhand what the manufacturer and noise reduction rating is for the old orange rubber earplugs is?  These are the ones that came in a clear plastic box with a small chain to attach the box to your pocket, webbing etc.

Lowest bidder comes to mind.... but I think they are LPO......

Likely a NRR of around 19-21, but I don't have a pair handy to check.  Why do you ask?

Something like this? I've searched for "GI Ear Plug NRR" in the google machine and it has punched out a number of 26, not 100% sure though as it's not a manufacturer spec.

NFLD Sapper:  These are the old, old ones issued about 15 years ago.  They last forever.  I'll try to post a photo.

ArmyDoc:  Because I use them at work.  They're extremely comfortable.  My employer is asking the NRR to ensure thet they meet health & safety requirements.  I really don't want to have to give them up for the foam disposable ones.

That's them, but with a different case.

Oh those... bought them a few years ago at the PX at Fort Picket....  but with these http://www.midwayusa.com/product/453211/peltor-indoor-outdoor-range-e-a-r-ear-plugs-nrr-22-db-1-pair?cm_vc=ProductFinding instead of the ones you are talking about....

Be advised, those NR ratings are done under laboratory conditions are don't translate 100% to the real world - or at least the shop floor.  The number's usually high.

Those are about the best I've been able to find around.

NRR of 33.

I did some market research a while ago, tracked these down, and have been using them ever since.

Available through Acklands-Grainger, and any major safety supply store.
