Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

So they say that the Army uses 4 PSI as a placeholder safety threshold while they gather data on this specific issue, but do say that threshold is based on prior not directly related research.
The .50 BMG is obv in a class of its own (completely smashing that threshold), but the only one that tickles at that threshold is the Desert Eagle (also a .50 caliber round).
Most of the firearms they tested rated in in the 1-2 PSI range....and as I was double checking that noticed their note: "Measurements shown are the average of the three highest readings for weapons fired from inside a range booth."
I don't mean to say there's nothing here, but this does feel alarmist. Nonetheless does seem like double hearing protection wouldn't be a bad idea.
It is interesting that a Model 1911 clocked in with a lower pressure wave than a "9mm pistol" (wonder which model(s) they tested). John Browning continues to flex from the grave.
I agree that it does feel alarmist, but to be fair, the article mentioned multiple times that the research isn't established just yet. In the end it sort of reminds me of the radiation doses from x-rays and CT scans. You have to weigh the potential risks with the potential benefits when deciding to practice with a firearm.
