They still sound like they would be better than the Howard Leights Impact Sport muffs. Those only have a decible rating about 22-25. The comfort level and convenience of these new ones might be much higher and they are rated for at least 31db. The cost is quite a bit different.george wrote:Okay, guys I was wrong.

My apologies.
I think at best with all of these electronic devices you should look at the noise suppression with them un-powered, such as 31 db, etc. This is the passive protection and the larger the db number the better. None of them really seem to use electronics to phase out unwanted sound (gunshots) but they do use electronics to allow you to hear surrounding sounds that you would not hear if the device was in passive mode only. The devices are supposed to shut off all outside noise (and therefore go into passive mode) at the first inference of a gunshot but the best you can expect is the passive mode db reduction. I will stick with the best passive device I can find that doesn't interfere with cheek contact of my shotgun and tend to say "what" a lot when people talk to me. From everything I have read there are no really good Bose type sound blockers ( 180 degree phase blocking devices) that will work for firearm noise suppression.george wrote:Okay, guys I was wrong.

The improved rating is exactly why I bought these. More hearing loss is something I don't need. A welcome side benefit is the ability to get a better cheek weld than I can with my Howard Leight muffs.C-dub wrote:They still sound like they would be better than the Howard Leights Impact Sport muffs.

I already have moderate-to-severe hearing loss. When I remove my hearing aids and wear plain old foam plugs, I can just barely hear people speak. That may be OK for solitary range time, but it''s a real bummer during "social" shooting, such as skeet with friends.rotor wrote:I think at best with all of these electronic devices you should look at the noise suppression with them un-powered, such as 31 db, etc. This is the passive protection and the larger the db number the better.

My understanding was that there was a passive level of noise reduction (31 db for these), the electronic circuitry allows sound below a certain level to come into the earphones (or buds) electronically and can even amplify it for those with hearing loss. Sound over a certain decibel level such as a gunshot cut off the circuitry so that no sound comes in electronically and you have a maximum noise reduction of the passive level, in this case 31 db. I have tried the Leight brand electronic muffs but they did not form a tight seal on my head and only were 21 or 22 db reduction. I can see the advantage for those that need a hearing aid or blue tooth as these can amplify voice and sound below gun shot level. My point to all of this was that if they provide 31 db noise reduction that is what you get when they are powered off (passive) and you never get more noise reduction with power on. What you do get is amplification of "normal" sound so that you can hear the folks talking. You never get more than the 31db noise reduction though and that is pretty good. If I am wrong about the mechanism of action please correct me. The web site of the manufacturer leaves much to be desired.george wrote:Rotor, any Bose type muffs would attenuate everything. That is not what we are looking for. We need muffs that attenuate the loud gunshots, but still allow (and even amplify) voices. This is the circuitry in most of the higher end muffs now (Peltor, MSA, Walker, etc.). That is, we can be in the midst of lots of shooting, but still hear range commands easily.
I believe you have a misunderstanding of how these work. You should try some of the electronic ones, you will not ever go back to the others.
The principle they us is dynamic range compression.
Thanks george. Helps my understanding of how these work.george wrote:Hey, Rotor
