  Don’t ear protection like the Razor Slims function both with active noise cancelling and without electricity? Active noise cancelling is useful for hearing the range instructor, but I’d imagine the seal and cushioning would also provide adequate hearing protection.

    Pretty sure mine are passive with a little speaker that selectively transmits low decibel sounds. If the batteries die, it’s still passive protection, I just don’t get to hear people talking.

    I use passive but my wife uses active ones from Walker. Their passive isn’t quite as good, but plenty for range use in case the batteries die.

    Razor slims have shitty protection if the battery dies, only 22db, which is not enough without also using foamies. Also their sound quality is dogshit compared to the equally cheap Impact Sport electronic muffs, which also sacrifice passive protection for slimmer dimensions. Proper passive muffs are 30-33db reduction.

      Huh, TIL. I do have a pair of purely passive muffs (from my father, presumably acquired in the 90s/00s) that I could use if need be. I got the Razor slims a bit back because of a clearance discount at a sporting good store, glad to hear there are other options in their price range though.

  And don’t forget cardio

  People should also be aware that shooting guns causes physical brain damage, so they should take that into consideration.

    But that’s just indoor shooting, right? (The page doesn’t work on my phone)

    I wouldn’t want to shoot much larger guns than 22 indoors routinely. But that’s maybe the viking in me talking ❄️⚔️🔥

      It’s all shooting, but the indoor galleries seem to make the concussive effects a bit worse.

    So does letting the nazis win.

    I bought my first firearm a few weeks ago because the risk of nazis showing up at my door had gone through the roof. Even if they don’t (and I still think the odds are good that they wont), we’re in for some massive food supply shortages this year. Even now, I’ve noticed that there are more runs on groceries, the quality, quantity, and variety of food in my grocery stores has dropped. I’m growing a big garden this year, which is the main reason I got the gun. If someone broke in before, my main plan to was to let them have whatever the fuck they want outside of the bedroom. That garden however, may be the difference between living and dying next year, and it’s not something I can just buy again, or pack up and scurry away with when confronted.

  I wonder if active noise canceling doesn’t have a delay that pretty much nullifies said protection in the case of quick loud bangs.

    For consumer bluetooth earbuds with a high level of latency (think what you’d use on your phone), certainly - which is why you should never try to use everyday use headphones as genuine hearing protection for things such as industrial environments or gunshots.

    Dedicated hearing protection devices perform all their audio functions locally with almost no latency at all (unless you count using an aux jack in conjunction for something like two-way radios, which don’t interfere with the noise cancelling).

    TL;DR - yes for devices not designed to protect your ears, no for devices designed as hearing protection (because of their specific design and operation).

      From what I understand, typically audio compression has about 20 ms of ramp-up, though it can be theoretically lowered about ten times — not sure how well it would work in that case, though. Consider that aural reaction speed is apparently way better than visual, wherein the latter is on the order of 200 ms. As is confirmed by musicians hearing a lag of around 15 ms. This leads me to believe that human hearing would probably pick up the shots sound before noise cancellation kicks in, otherwise the cancellation is too sensitive for anything else to be heard.

  Active ear protection become passive when the batteries fail. The active part is that they have microphones on the outside so that you can hear normally with them on. I do agree though that noice cancelling headphones should not be used as hearing protection.
