    What are you doing surfing the net?

    You're supposed to be vigilantly protecting us from Rooshian spam.

    Mister Wilbur I bought a set a few years ago. They lasted about 5 seconds. They broke when I tried to put them on. I did call Grizzly and they were nice and refunded my money. Was told to keep them or just throw them away and I wasn,t the only person that had the same problem.

    "25dB Noise Reduction Rating (NRR)"

    Not all that good.

    I didn't find those things searching but rather I get an email every 5 minutes from Grizzly telling me I should buy something....every two minutes if I click on an item.

    I turned registration back on for a fellow to register so Y'all shoot me an email when you see a spammer...Rooshian or not!

    Nrr

    interestingly the NRR rating of a muff or plugs is not a direct number reduction. If you are exposed to 100 dB noise a 30 NRR rated muff doesn't reduce the noise to 70 dB. you take the NRR number subtract seven and divide by two. So in the above case the actual reduction is (30 dB - 7)/2 = 11.5. So the 100 dB noise would be reduced to 100-11.5 = 88.5 dB. i think the EPA is considering a change. it will still be called NRR but will be a range to account for trained motivated user use vs. those who do not use them correctly. Anyway i use both muffs and plugs in which case you add 5 to the highest dB rated device you are using then use the above method.

    The whole system of trying to measure impulsive noise does not actual work that well.

    The typical amplifiers do not have adequate bandwidth to deal with the very small rise
    time of a a sound impulse like a gun shot, or even steel on steel impact noise.

    Bandwidth of any signal is approximately .35/rise time.
    A 1 us (microsecond) rise time requires a bandwidth of around 350 kHz in the electronic system trying to measure it.

    And amplifiers with that kind of bandwidth are a real chore to build and stabilize.

    Nothing lasts forever,

    Not even our ears. I have used good plugs and muffs, together, while shooting CF rifles for years and the plugs only for RF and @ 75 only have half my hearing left. At least the new hearing aids answer my phone for me and allow me to talk without handling the phone. Background noise though is still a huge problem.

    How many rounds of ammo can you shoot for 10 bucks?

    Well, If they work, that is a bargain.

    If they don't work or last, you are not out much.

    If you all ready have something that works, you don't need them.

    Wilbur. With all due respect.

    What do you value more?

    Your health and your hearing or saving a few $$$?

    I am ex Australian Army. Stood near to too many big guns. 155 muzzle brake (or even a 105) messes with your hearing whatever you are wearing.

    It was fun when I was a kid; - Now I regret that decision.

    If I had my widdershins then would advise to use the best protection that you can afford.

    And stay well clear of muzzle brakes

    I bought 5 pair for our back yard shooting. Better than no protection.

    Some money and some hearing damage.

    One is a lot more important that the other.
