Turn your iPhone into a practical car noise meter, NVH test journal, and noise diagnosis tool. NVH Lab helps drivers measure cabin sound, diagnose why a car is loud, and compare repeatable drive tests. Use it to establish a baseline, document a new hum or rattle, and check whether a tire, road, or vehicle change altered the sound you experience. CAR NOISE METER Record A-weighted cabin sound levels during a repeatable route. Save the test conditions so your next result is easier to compare. FREQUENCY SPECTRUM See where sound energy appears across the frequency range. The spectrogram helps distinguish low-frequency rumble from mid-frequency hum and high-frequency hiss. NOISE DIAGNOSIS — WHY IS MY CAR LOUD? The guided diagnosis reads your recordings across speeds and road surfaces — with community data when available — and names the most likely cause: tire roar, wind and seals, engine or exhaust drone, or rattles. See the evidence, get fixes ranked by cost and effort, then prove the result with a before-and-after project. BEFORE-AND-AFTER TESTS Compare the same vehicle before and after new tires, insulation, maintenance, or a repair. Matched route, speed, phone position, and weather make the result more useful. GARAGE AND COMMUNITY Keep vehicle-specific recordings in your garage, follow model discussions, and contribute privacy-protected aggregate results when you choose to make a session public. Public feeds never expose recording coordinates. BUILT FOR REPEATABILITY NVH Lab flags clipped or unstable recordings and preserves test context. It is designed for relative comparisons with the same device, not as a replacement for a calibrated professional sound-level meter or a mechanical inspection. Results depend on the phone, microphone, placement, route, speed, and environment. Do not use the app to make safety-critical repair decisions. If a noise is sudden, severe, or accompanied by handling, braking, temperature, or warning-light changes, stop driving and seek qualified help. ## Version history (last 5 releases) ### 1.82 — 2026-08-20 Guided Diagnosis You Can Trust • A more trustworthy diagnosis — the app now checks with you before calling a verdict • Better at finding wind noise, whistles, and hisses • New quick checks you can do parked to help pinpoint engine-bay noises • Guided diagnosis runs are now private, neatly organized, and easy to pick back up • See results as each diagnosis test finishes, and wrap up whenever you’re ready • Smarter diagnosis — guided tests and richer recording data help the app pinpoint your noise source faster • New accuracy badge on recording cards shows how trustworthy each test is at a glance • Calibration is now simpler and more automatic • Smoother profile lifecycle — from choosing your name at sign-up to managing your account, everything is now more reliable and predictable • More reliable recording uploads — failed uploads now retry automatically • Fixed an issue that could block saving your car ### 1.80 — 2026-08-17 **Improved** - Various fixes and improvements for a smoother experience ### 1.79 — 2026-08-16 Notification Center & Reputation Tiers • A new notification center — real-time updates for referrals, tier-ups, moderation decisions, and automatic flags, delivered to the bell inbox • Six reputation tiers with badges, quality and consistency multipliers, and a celebration when you level up on save • Badges and points are now saved server-side, so your progress stays in sync across devices • Your public profile now shows your real reputation tier, and community cards display accurate reaction counts • Recordings that are flagged or awaiting moderation no longer appear in public feeds ### 1.78 — 2026-08-15 Fleet Intelligence & Spectrum Studio • Fleet intelligence flags unusual noise patterns in your recordings • Plain-language fleet ranking for your car • Spectrum Studio with your choice of analysis engine • Live waterfall with new colormaps and automatic recovery • Road-surface recognition for your recordings • Rate your car's ride and see community-validated trim details • Sign in with Apple works reliably again • Faster app start and post-update reliability fixes ### 1.68 — 2026-07-23 Version: 1.68.0 — "Notifications, Rebuilt" (2026-07-23) - [feature] Push notifications for everything in your inbox — follows, comments, club invites, and likes now reach your lock screen - [feature] Likes are back — batched into a single "X and N others liked your recording" notification - [feature] Quiet hours and per-type notification controls in Settings, with automatic timezone handling - [feature] Optional weekly reminder to capture your 10-second drive test - [improvement] Unread count now shows on the app icon - [improvement] Notifications stay fresh on slow connections and across multiple devices - [fix] Tapping a notification now marks it as read instead of deleting it ## Apps similar to NVH Lab | App | Rating | Price | Category | | --- | --- | --- | --- | | [Rattlewise: Noise Finder](https://appshunter.io/ios/app/rattlewise-noise-finder/id6775386195) | — | Free | Utilities | | [AcceloVibe](https://appshunter.io/ios/app/accelovibe/id6747295321) | — | Free | Utilities | | [Shake Meter - Hand Tremor Test](https://appshunter.io/ios/app/shake-meter-hand-tremor-test/id6766421039) | — | Free | Utilities | | [MyMilpitas](https://appshunter.io/ios/app/mymilpitas/id693008118) | 4.4 (71) | Free | Utilities | | [NVH](https://appshunter.io/ios/app/nvh/id1026086455) | 4.2 (24) | $99.99 | Utilities | | [Watermark ID Card Protect](https://appshunter.io/ios/app/watermark-id-card-protect/id6749518545) | — | Free | Utilities | ## Related topics [nvh2021](https://appshunter.io/ios/topics/nvh2021) · [nvh source locator](https://appshunter.io/ios/topics/nvh-source-locator) · [nvh](https://appshunter.io/ios/topics/nvh) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
