Real-time dB & noise scoring
Flutter app that streams microphone input into approximate decibel readings, runs timed measurement sessions, scores the environment against common noise bands, saves history on device, and offers CSV export and charts. Monetization via ads and a one-time Premium unlock for extended features.
Start and stop timed sessions; see min, max, average, and category labels with plain-language recommendations.
Past sessions stay on your device; export CSV or share summaries when you choose.
Unlock longer or custom durations and richer charts where enabled in the app.
Real app screens from Noise Meter — Shusher.
Real-time dB gauge and waveform while you measure.
Average, min, max, noise category, and tips after each session.
Set a threshold and get in-app nudges when noise crosses your line.
Compare rooms and times — data stays on your device.
Longer sessions, charts, CSV export, themes, and no ads.
Grant mic access when prompted so the app can estimate ambient level.
Watch the live meter or tap Start measurement for a timed session.
See average, category, and recommendations on the results screen.
Add to History or share a clean results graphic with a label.

1. Same spot every time — compare “apples to apples” when tracking a room over days. 2. Mic unobstructed — remove thick cases; don’t cover the bottom edge (common mic location). 3. Orientation — pick portrait or landscape and stick with it; mic direction changes slightly. 4. Height — ear level for “how loud does it feel?”; desk level for workspace noise. 5. Distance — 0.5–1 m from the main noise s
| Goal | Suggestion | |------|------------| | Quick snapshot | 5 s (default) | | HVAC cycle | 15–30 s (Premium) | | Conversation level | 10–15 s while people talk naturally | | Street noise | 30–60 s (Premium) to catch peaks | ---
Steady hum (fan, AC constant) → simple average is fine. - Bursty noise (dishes, traffic, classroom chatter) → switch to energy average (Leq) in Settings for a fairer score. ---
| Scenario | Starting threshold | |----------|-------------------| | Library / study | 45–55 dB | | Open office focus | 55–65 dB | | Living room with kids | 65–75 dB | | Workshop / garage | 75–85 dB | Lower the threshold if alerts rarely fire; raise it if too sensitive. ---
1. Measure before a change (rug, curtains, door seal, “quiet hours” sign). 2. Apply the change. 3. Measure after at the same time of day. 4. Save both to History with clear names. Small dB drops can mean a noticeably calmer space. ---
Use neutral labels: “Tuesday 8pm apartment” not “neighbor noise proof.” - Share the results graphic for a single snapshot—not a live argument meter. - Remember: phone readings are approximate, not legal evidence. ---
Don’t speak directly into the mic while measuring ambient noise. - Move away from TV speakers and phone notifications. - Wind outdoors can spike readings—shield the mic or measure indoors. ---
Consider Premium if you: - Export CSV for a landlord, school, or internal report - Need session charts to see spikes during a meeting - Want longer samples and no ads during repeated daily checks One-time purchase—no subscription. ---

A mobile app that estimates ambient sound level using your phone’s microphone, runs timed measurement sessions, scores the environment, saves history on device, and optionally alerts you in-app when noise exceeds a threshold (Shusher).
Yes. Core metering, sessions, Shusher, and limited history are free. Premium is a one-time upgrade for charts, CSV export, longer sessions, themes, more history, and no ads.
Both. Bundle ID: `com.zuki.apps.noisemeter`.
12 locales including English, Hebrew, Arabic, French, German, Italian, Japanese, Korean, Chinese, Portuguese, Russian, and Spanish. Change language in Settings.
It is an approximate level based on consumer phone hardware. Position, case, wind, and device model all affect results. Not calibrated for professional SPL, OSHA, or legal noise-ordinance enforcement.
Professional meters use calibrated microphones and specific measurement standards. Phones are tuned for speech and vary by manufacturer.
Use readings as informal context only. For legal or compliance matters, hire a qualified acoustician with calibrated equipment.
No continuous recording or cloud upload of raw audio. The app processes level data locally for metering and sessions.
While the app is open and metering or running a session—not as a background listener.
Free tier uses ads. Apple requires permission before personalized ad tracking. Premium removes ads.
No. They appear inside the app while the live meter is active.
Check: Shusher enabled in Settings · threshold not set too high · meter tab open and mic running · live level actually exceeds threshold.
