So passive noise cancellation is basically that. Just good insulation.
But active noise cancellation is pretty high tech and feels a bit like magic when it works well. The last time I was on a plane and had my AirPods Pro 2, it felt really great to take down the background engine noise down by a lot.
Aha, thank you for making the distinction. It may be the case I have never used "active" noise cancellation, but that use case you mentioned is really intriguing. It just so happens I am going to be in the market for headphones when I get back to the U.S., so it may be a good time to test it out!
I'm a big fan of the Airpods Pro v2. Small enough to always be in my pocket, good quality for music, and the noise cancellation is very effective for something that small (and not huge over the ears headphones). Perfect for podcast listening.
I’ve heard similar things, I’ll test out a pair from a friend and maybe I’ll buy some 🤷🏻♂️. I have quite a hard time in my gym because they sometimes play loud music. I would REALLY love to cancel that out 😂
Not to be nit-picky - OK, just a little - the fiber optic diagram mis-identifies the cladding, which is a glass layer surrounding the fiber core and has a slightly different refractive index. The diagram has it outside the metal strength layer. With the naked eye, you can't distinguish between the core and cladding - it's just a tiny string of glass.
The cool thing about fiber is that the ultimate bandwidth is only limited by the electronics that feeds it. The frequency of laser light is around 5X10^14 HZ. With two cycles needed to define a bit, that would be about 150,000 gigabits/second. And then multi-mode fibers can transmit hundreds of different frequencies at the same time. Gives you some insight on how Infiniband works in those Nvidia data centers. Jensen: "240 Terrabytes/second" Yikes.
The combination of AI and Nvidia's accelerated computing is like discovering fusion reactors that could power a single house or car or scale up to power factories orders of magnitude larger than possible today - all for the gasoline equivalent of one cent per gallon. Unlimited upside.
I thought there may be something wrong with it looking at it, and one part wasn't identified, but I don't know enough about fiber construction to have been sure. Thanks for the correction/precision, I appreciate it!
Super cool re: noise cancellation.
I had assumed that noise cancelling headphones / earbuds were designed to be good physical barriers to outside noise. Mind blown 🤯.

It probably won’t remove it a hundred percent, but it should help a lot versus no noise cancelling headphones
