I have followed the advice of others and gone ahead and purchased the Howard Leight Electronic Impact Pro Hearing Protection Earmuff NRR 30. I tried it with my original test and it was very successful as I could hear footsteps when somebody is walking around the main floor and up the stairs. I tried it at my local range as well and I could have a normal conversation while receiving protection from the gun shots or report. I am yet to try it with my 12GA and see whether the protection will be the same as the pistol rounds. ( I believe it would). Anyway, I bought two so my wife can have one for herself. I paid $75 for each at optics planet and I believe it was a worthy purchase. Thanks
