70 is the line. Anything below that will never cause damage.
Above that depends on how long the exposure is. A hair dryer is ~90db. For a several min that's not realy a problem. 125db is jackhammer range. That could be okay for a couple seconds, probably not 20 seconds.
Be wary, pea-based whistles will freeze up from humidity from blowing. And they won't work in the rain either. SOS has a non-lanyard one that's pealess, and idk where you're planning on deploying 500+ whistles but if it was in a cold area or a wet area they'll fail. And they probably will fail if blown on continually in dry conditions due to moisture as well.
Just remember no buying things today! Especially Amazon
... But, death whistle
Find a local woodworker who can make it for you and barter for it. Barter/mutual aid isn't capitalism
... Or wait until tomorrow lol
Or 3D print one.
The money doesn't make it capitalism, the worker not profiting from their labor makes it capitalism.
Sure. But once you start to involve banks you inevitably get into exploitation.
But yeah, it isn't the paper that's the issue, it's the system.
You mean fraudulent trash, playing on the current drama to milk you out of your money?
Probably doesn't even make sound.
haven't used amazon in like 3 months, and i don't plan on using it today especially
it's all child labor plastic slop
China doesn't just make everything, they're basically the only ones who can make most things, AT ALL.
It's profoundly depressing.
WHOOOOAAAA
You need to put a content warning or something for that site
I know it's disgusting
Doesn't ear damage start at like 90dB?
...still, 25 bucks for a DEATH WTHISTLE!

That's like some of those videos of spooky "sky trumpet" sounds!
I wonder if it's the explanation for some of them.
all i know that this horn is called carnyx and they are used by the celts on occasions like celebration, war, etc.
Dang I could ask my bro to 3d print
Is your bro aztec?
And a frickin coupon!

Find someone with a 3d printer. Your local library might have one even. I'm printing 55 whistles every 6 hours for around 7 cents a whistle.
Ew, Uline.
