peetzakilla: The Noise Reduction Rating on those things is 7db.... in gunshot terms, that's virtually like wearing nothing at all.
By the numbers, 7 doesn't sound like much. But based on experience and a bit of dabbling in sound testing at work, you have to understand that the NRR values are weighted, and based on a broad spectrum sound measurement. These play fair with everyone else by providing a NRR rating. From 20Hz to 20,000Hz, the overall reduction may only be 7, but in the range that matters as pertains to a muzzle blast, they work pretty darn good! I'm not playing favoritism... just think you might be surprised. I was.
