Hey HN, I built nycnoisecameraticket.com to help drivers fight the new automated noise tickets in NYC. The Engineering Challenge: NYC is deploying microphone arrays to pinpoint loud cars. But NYC is also a "concrete canyon." Sound reflects, reverberates, and amplifies. The Dispute Strategy: My tool generates defenses based on the limitations of acoustic triangulation in complex environments. The "Canyon Effect": Was the reading distorted by a nearby glass building or construction wall? Ambient Interference: Was there a siren, jackhammer, or subway grate rumble nearby? Source Ambiguity: How does the camera distinguish your engine from the modified Harley in the next lane? If the city wants to fine people $800 via algorithm, the algorithm needs to account for physics. My tool helps users demand that proof.
