NVH Tracker

NVH Tracker — Find That Rattle, Squeak or Buzz Is there an annoying rattle, squeak, or buzz somewhere in your car that only shows up over bumps or at certain speeds? NVH Tracker turns your phone into a mechanic's stethoscope, helping you pinpoint exactly which panel, trim piece, or component is causing the noise — no expensive diagnostic visit required. HOW IT WORKS: THE CONTACT PROBE METHOD Start your car, reproduce the noise, then lightly rest your phone against suspect panels one at a time. NVH Tracker analyzes both sound and vibration in real time, so you can watch the readings spike the moment you find the source. KEY FEATURES Live Audio Spectrum Analysis See a real-time FFT frequency spectrum (0–22kHz) of the sound picked up by your microphone, helping you classify and isolate the type of noise you're hearing. Vibration Tracking Your phone's accelerometer measures the physical vibration transmitted through each panel, giving you a second data point to confirm what your ears are telling you. Blind Mode Keep your eyes on the road or your hands on the panel — Blind Mode delivers audio and haptic feedback so you don't need to stare at the screen while probing. Diagnostic History Tag and save readings by location as you work through your car, so you can compare panels side by side and build a record of your diagnostic session. Privacy First All audio and sensor processing happens entirely on your device. Nothing is recorded, uploaded, or sent anywhere — your data never leaves your phone. Multi-Language Support Available in multiple languages so more drivers can diagnose their own vehicles with confidence. WHO IT'S FOR Whether you're a DIY car enthusiast trying to save on workshop fees, or you just want to describe the problem more precisely before your next service appointment, NVH Tracker gives you the data to back up what you're hearing.
