An electronic circuit that
- captures the horn sound waves (could be multiple)
- find the source of the sound waves
- use directional speaker to return the sound waves back to the honker
i know its silly. i know wearing ear buds will help.
still, is this possible? no one seems to have worked on this. is there a working device?
So basically one of those
plugged to one of those?
It’s definitely possible the US military did it back in Vietnam to determine the direction a gunshot came from. It requires 3 microphones and should be fairly easy for a computer to do the calculations.
yep… connect them to ADCs to convert the sound to digital, then have a computer check the offsets and calc approximate angle. If you can reduce your target to 180 degrees (facing a roadway) then you only really need two microphones… or if you need full 360 degree coverage, 3 microphones arranged in a triangle should do.
