I once wanted to make something similar, for sound. I wanted to create active noise cancelling "in the room", instead of via headphones. I pictured these devices combining a microphone and a speaker that you could set up in strategic location. After thinking about it for a bit, I realized that inference would cause areas with silence and others where the sound volume would be doubled. Less than ideal but still possib…

If that technically worked, I could see that being a next unicorn.

It can work (Look up beamforming). However it takes a 3d array of speakers with a lot of elements positioned in specific points in space, as well as very accurate position tracking for both ears. Very very unlikely to ever beat a high end noise cancelling headphone in terms of performance as well.

If the listener can be fixed in space then the problem gets easier but in that case what you have is actually a very large, room sized headphone that you enter and sit down into.

Source: I indirectly consulted a high-end furniture company on this exact project, they decided to pivot after a while.

If you had a "sound laser", you could control the waves when entering a column (think a "sound umbrella") to cancel out sounds that enter. However, this only works for "regular sounds" (as in non-directional sound, like sound from distant sources, like speakers). So, it wouldn't cancel out things like people speaking. It would be pretty useful for clubs, where at your table you can have regular speaking conversations.

I hate to mention that this is all currently patented. It's pretty "easy" to build though, but you'll have to wait a bit for all the related patents to expire or pay some licensing fees.

Badass on the visualization side. The multiple emitter portion and the end of the scroll reminded me of https://apenwarr.ca/beamlab/ which demonstrates beamforming (adjusting the phase of adjacent transmitters to focus power towards a specific receiver). To play with this one the "easiest" way to see what's going on is go to the right hand menu, unclick 3 so you just have 2 transmitters, click the "r" button, and the…

Came here looking for a mention on Hamina - I use it for work for planning wireless installs and it's a really decent piece of software.

I just tried to signup for a new Hamina account... and I've failed after spending 15 minutes on it. It seems they have a bug in the last step of the signup process that makes the final "continue" button always be disabled. Forcibly enabling it by modifying the DOM appears to work at first and lets me submit the form, but it doesn't result in a new account being created.

I have a suspicion it's flagged my signup as potentially abusive or something due to my various privacy enhancements...

What are the system requirements to run this? Fairly 'standard' Linux system running Chrome here. "Sorry, there was an error starting the simulation Sorry, WebGPU is not supported on our device WiFi Solver may not be compatible with your device."

hasn't webgpu standard been out for a while now? how come only chromium supports it?

Cause chrome took over the world and is putting back in the place of IEs monopoly
