A noise-rating layer for apartment listings that helps renters in Chinese megacities screen out noisy units before signing a lease.
Renters in big Chinese cities repeatedly sign leases and discover only after moving in that the unit sits next to an elevated highway or under a flight path, then lose money on early termination and a second move. Rental platforms show price, photos and subway distance but nothing about actual noise, so people rely on exhausting in-person visits and luck. A crowdsourced building/unit-level noise score plus traffic and flight-path overlays would let renters filter listings before they ever travel to view them.
The problem
Renters spend weeks viewing apartments, still end up in units with highway or airport noise, then pay for early lease termination, moving trucks and another deposit — each bad move costs thousands of RMB and weeks of energy. There is no way to check a specific building's noise level from a listing; the only signals are a short daytime viewing and the landlord's word.
What could be built
A mobile-first database where renters submit short phone-decibel measurements and tags (highway, flight path, construction, thin walls) tied to a building address, aggregated into a per-building day/night noise score. Overlay official highway and flight-corridor data to pre-score buildings with no submissions, and offer a paid 'noise report PDF' for a specific address or a browser extension that shows the score directly on rental listing pages.
