Here have some Reddit gold 🏆
That got a genuine laugh from me.
Username checks out. Hope you didn't spit out your prune juice!
Terminally online VR when
This is absolutely fascinating and the first I've ever heard of such tech. As a musician, I'm excited to see where this may go? Thanks for posting!
The problem with all of these devices is that there is a lot of noise power in the world. A jet engine is loud because the acoustic energy it produces displaces large volumes of air very quickly. To cancel that energy, you also have to move huge volumes of air. Headphones are good at this, in part, because they attenuate so much energy in the first place with an over ear headphone, or well sealing IEM, and place the speaker very close to your ear. A source of acoustic energy which is D meters from your ear has to produce at least D^3 more joules than a speaker right next to your ear, to cancel the same amount of noise. It's possible, kind of, with very big speakers, but a handheld device just won't cut it.
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?
That sounds like tinnitus
The fact that the article talks about how cheap they are to produce makes me suspect that whatever company ultimately sells them is going to mark it up to hell and back.
What part of living in a country where producing a bottle of Insulin costs about $4 and a month supply for a patient is about $3,000 a month caused you to think that?
That would be cool. You could live right next to train tracks or an interstate and not have to hear it
I assume the "100% effectivity" only applies to canceling unchanging, known waveforms.
Also, what's the power use of these things?
After reading, I was somewhat disappointed that it's a clever tiny speaker mechanism. Much more fun to picture Blofeld walking down the hallway in his lair and pushing the noise cancel button outside a raucous conference room resulting in immediate silence and a distressing burning smell.
Landlords will still never put these in, I suspect they like the noise complaint calls
They like to be reminded how miserable you are
I wonder if there's a limit to how loud of sounds it can cancel? Can I have a mini rave in my garage without bothering my neighbors (I mean other than the chill out area forming on their lawn).
Maybe I missed it, but are they suggesting this is omnidirectional? As in, do I need to be standing in exactly the right spot for it to work?
I'd love to see how well this cancels out some subwoofer loving neighbors I've had in previous apartments. I'm skeptical considering the level of wall shaking vibrations that are generated from some systems, but I'd pay a decent price if it actually worked.
