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.
Bikes, trains, busses, scooters, pedestrians, ... are all traffic.
Two of those are mass transit and the rest don't make very much noise.
50cc scooters are the worst, actually. Nothing like hearing the high-pitch squealing sound comparable to a leaf blower in your ear at 3am. I’d gladly see them banned from the city.
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!
This is fascinating, I will look more into it.
