I feel like we are ways out from seeing anything like it. From what I’ve seen non-Newtonian fluids typically take a decent amount of energy to stop something and sound wouldn’t have much energy compared to something like a bullet....
I don’t see how anything non-Newtonian would be better against sudden sounds. In fact it would be worse, as they’d get more solid and thereby transmit MORE of the noise you’re trying to block out. Or maybe they only get more rigid but their sound transmission properties don’t change at all. Either way, sounds somewhat pointless.
The only way I can think that something like this would work would be to have a molded vacuum chamber as an ear plug, with a specifically engineered sound transmission bridge inside. With too much energy trying to go through, it would break. But I doubt it would be quick enough to be effective, and they’d also be one time use, and extremely fragile.
A quick search tells me this have to do with shear forces. Sound would be entirely compressive, so those material properties would have no effect, or at least not change due to sound levels.
So, I’ve been reading about the MIT bio suit. It’s basically a pressurized helmet and gloves, and a fancy fabric suit with bands that squeeze you with enough pressure so decompression doesn’t kill you....
Your body IS being constantly pressurized by the atmosphere, and your various sphincters are used to that. Presuming the suit doesn’t pressurize your body beyond what it’s used to (at which point breathing would be difficult), there should be no unexpected anal excretions due to the suit.
As the title mentions, the company I work at is offering free shares when buying back some of the company’s shares, as well as a discount, depending on the amount of shares purchased....
If you can’t determine whether this is a good idea, then it’s not. If you knew how to assess the value of the company against share price and total shares, the math would tell you whether it’s worthwhile.
For a n00b don’t start with investing in individual companies, just start with something that mitigates most of the risk. Presuming you’re young, a “high risk” mutual fund would probably be an appropriate start. If your risk tolerance is low, a growth fund is probably what you want.
If you have cash to burn, go ahead and YOLO in the stock market, but please get more information than what you’d find on WSB. Meme stock loss porn is real.

Could non-Newtonian fluids be used in the future as a kind of percussive ear protection?

Would a mechanical counter pressure suit make you poop?
