Cool video. I think helmholtz resonators are wildly underused and could improve a lot of spaces like restaurants, living rooms, and offices.

Can I have noise cancelling armour made out of them?

Or noise cancelling underwear at least

I just watched this earlier today, interesting concept. Now I wonder about the other commercially available hemholtz resonators that he mentioned.

Did a quick search, here's somebody selling a block that seems to have a similar function: https://www.soundseal.com/soundcell

In that case, someone should work on my idea instead: drones that use an array of microphones to pinpoint where a car horn comes from, and launches rotten eggs at it.

There's a good reference prototype you can check, it's from the early 2000's featuring its debut in Malcolm in the Middle!

Can we not just get rid of the traffic instead?

And what, move everything online and plug ourselves into the matrix?

Bikes, trains, busses, scooters, pedestrians, ... are all traffic.

So if you want to move around the world, you will need traffic.
