Hey HN,
I launched nycnoisecameraticket.com to help New Yorkers automate disputes for the city's new "SoundVue" noise cameras.
The Context: NYC has started deploying microphone arrays (acoustic cameras) that triangulate sound sources. If a vehicle emits >85dB at 50ft (roughly the volume of a lawnmower), it triggers a camera that snaps your plate. The problem? The fines are massive ($800–$2,500), and even stock vehicles (like standard Porsches or Jaguars) are triggering them just by accelerating normally.
The Problem: The "Notice of Liability" is often vague, but the defenses are technical (calibration logs, microphone distance certification, ambient noise interference). Most people just pay the $800 because hiring a traffic lawyer costs more.
The Solution: I built a specialized LLM workflow that:
Ingests the ticket details (location, time, alleged dB reading).
Generates a specific legal defense letter citing the NYC Noise Code (Section 24-237) and requesting the specific calibration records for that camera unit.
(In progress) Automates the physical mailing via the Lob API so you never have to touch a mailbox.
The stack is React/Lovable on the front end + Supabase. I'm looking for feedback on the "stock vehicle" defense logic if anyone here has experience with acoustic engineering or NYC administrative law.
