EPFL researchers have developed a 100% effective, ultra-thin active noise cancelling system that uses an ionized air plasma propulsion system instead of speakers. A 17mm (0.6 inch) thick layer can block 20 Hz noise as well as a 4m (13 ft) thick wall.
I wish I had one of these to cancel the fireworks in my neighborhood that have been going off all week into the night
I saw a lady wearing a shirt that read “I can’t hear you over the sound of my freedom ringing 🦅🦅” so maybe if you just lean into the 'Murica it’ll be quieter?
