Are there more details as to how this works and how it prevents false positives? Would the rumble or crack of thunder and lightning trigger a microphone to incorrectly mark a vehicle as loud? Or are there algorithms processing the recorded sound beyond just pure dB/volume to determine if it's actually a muffler?
- acid__ 5y agoOne option could be to use an array of microphones to detect the source of the loud noise
- Gigachad 5y agoThis is how they do work, at least in the paris trial. Multiple mics around which can locate the source of the sound. They can also just record the sound + video and play it back in case of a dispute.
