No, that's a different ballgame again. The type of compression in hearing aids is full dynamic range syllabic with additional max output limitation and you really need the slower AVC/output compression type circuits to pull constant noise down to less than 85 dB(A) continuous
Interesting thread.
I work with Simon 01 and he is Ex German army. We work in a noisy workplace and this morning he brought these earplugs to work. Cost a couple of euro's only and non electronic.Just soft plastic(not foam) with a membrane inside that shuts the noise off over a certain level.
Shooting 5.56 and .270 they work wonders,semi auto and full auto, and yet you can use a walkie talkie or hear/converse normally with them. Going to be ordering a few from a website in Germany as the company in nz doesn't have them listed and seems un interested in getting them in.
Apparently the German army uses these by the boatload they are so effective.
What really interests me is the electronic version that's supposedly only a few hundy. He's going to send the german website that sells them so I can have a looksee.
Have not seen anything in Nz to equal these,especially at these prices, and I have bad tinnitus so really keen to find out more.
Best plugs I bought were a pair of sonic defenders through the bushbuck website, you can still hear about 80% and they cut out any gunfire, fit nicely in the contours of your ears, about 40 bucks from memory. Way better than the foam ones I used to use by a mile.

They will have some sort of -passive- non-linear filter in them. The description of having some sort of valve is only an analogy, like the Lee Sonic Valve.Quote:

Contact your nearest Triton Hearing clinic and get them to check with Chris in Napier on the filter details when they're doing the order
Hey there,
Old thread but is this still a thing 6x47? I need some plugs to replace a set of muffs as I have to wear glasses for shooting now and don't want the crush to give me a sore head.
On another note, how good are the sonic defenders?
Cheers
Yes, custom programmable electronic plugs are still available but will never be cheap. I use nothing else as I like flush protection and want to hear all that's going on around me.
When you say "sonic defenders", you mean the Lee ones? If so, I've never read any serious tests of these but they'll be 100X better than no protection. Remember that any passive device will never allow you to hear lower level stuff perfectly but it should take the damaging peaks out without you being too cut off from normal sound.
I was talking about the Surefire sonic defenders, Surefire do other stuff that is very good, so I thought their EP7 might be good too.
I have used the ep7 a lot for both shooting and being around jet engines and seem to do the job nicely. Nice and easy to flip the plugs out and hear people talking.
Sweet as, done!
