NVH Lab: Test & Rank Cars
Sound meter car noise analyzer
Free · Designed for iPad. Not verified for macOS.
Tired of guessing if that sound deadening actually worked? NVH Lab turns your iPhone into a professional car noise diagnostic tool — a precision decibel meter, live spectrogram, and vibration analyzer in one app. Stop relying on feel. Start measuring with data.
Whether you're a DIY mechanic proving new tires reduced cabin noise, an enthusiast comparing exhaust tones, or a driver benchmarking your car's quietness against a global database — NVH Lab delivers lab-grade acoustic diagnostics without expensive equipment.
WHAT MAKES NVH LAB DIFFERENT
Most sound meter apps show a dB number and stop there. NVH Lab is built for one thing: understanding and improving your vehicle's acoustic signature.
BEFORE & AFTER COMPARISONS
The reason you downloaded this app. Add sound deadening mats? Swap tires? Install a new exhaust? Compare recordings side-by-side and see the delta in real data — not your imagination. Road roar down 15%. Cabin drone reduced by 8 dB. Proof, not opinion.
LIVE SPECTROGRAM & FFT ANALYSIS
See exactly where noise lives in your cabin. Pinpoint wind hiss (high frequencies), engine drone (midrange), and road roar (low end). Tap any frequency band for instant insight into what's making your ride loud.
NVH QUIETNESS SCORE
Every recording generates a proprietary composite score (0–100) weighted by speech clarity, perceived loudness, and boom. Rank your vehicle against thousands of others. See where your car stands on the global leaderboard.
CABIN ACOUSTIC FINGERPRINT
Go beyond road measurements. Find and fix rattles, buzzes, and standing waves — like an acoustics engineer for your car interior.
VEHICLE GARAGE & TUNING JOURNAL
Build your garage profile, scan VINs with your camera, and log every modification. The Tuning Journal tracks tires, soundproofing, and upgrades over time — so every recording is tagged with exactly what was on the car when you captured it.
CAR COMMUNITY
Share comparison reports, and compete for the quietest — or loudest — ride. Discover what other owners achieved with the same car. The world's first social platform for automotive acoustics.
BUILT FOR ACCURACY
Software-controlled microphone calibration with cloud-vetted device offsets for consistent, repeatable measurements.
Privacy by design. Location data never appears in public feeds or profiles. Your private recordings stay invisible to other users.
Download NVH Lab, hit the road for your first Drive Test, and join the global community of drivers who measure what matters.
