A low-cost smart-city noise classifier that labels urban sounds (jackhammer, gunshot, street music, horns) on Raspberry Pi–class nodes using MFCC + SVM/KNN — going beyond dB maps to actionable noise type.
Last verified 15 Sept 2026 · Updated 23 Sept 2026 · Metadata v4
Problem
Municipal environment and public-safety units that must refresh END-style noise maps and respond to complaints, but today only store SPL averages every few years.
Outcome
A deployment-ready foundation that teams can configure into production.

About this foundation
On-node urban noise typing. WHO guidance cites bedroom <30 dB and classroom <35 dB; END 2002/49/EC demands multi-year noise maps, yet harmful events last minutes and same dB can be music or menace. CivicEar productizes MFCC features with SVM/KNN on Pi Zero W + mic HAT, ~3042 UrbanSound8K/Sound Events clips across eight classes, 85–100% accuracy, and sub-second KNN train/test on-device.
