1. Real-Time Measurement
- Watch live decibel readings on a beautiful arc gauge with a smooth needle and peak hold indicator. The scrolling dB graph shows sound level changes over time at a glance.

2. Min / Avg / Max Stats
- Track the minimum, average, and maximum decibel values for every session automatically.

3. Threshold Alert
- Set a custom dB threshold. When noise exceeds the limit, you'll get an instant vibration and sound alert — great for monitoring noisy environments.

4. Calibration & Response Speed
- Fine-tune your measurements with a ±20 dB calibration offset. Switch between fast and slow response modes to match your needs.

5. Measurement History
- Every session is saved automatically. Review past measurements anytime — date, duration, and min/avg/max values all in one place.

6. Noise Level Reference Chart
- Not sure what a dB value means? Open the built-in reference chart to see what everyday sounds correspond to — your current reading is highlighted in real time.

7. Dark & Light Theme
- Choose the look that suits you. Both themes are optimized for comfortable use indoors and outdoors.

8. Background Measurement - Keep measuring even when the app is in the background. A persistent notification shows the current dB level so you're always in the know.

Whether you're checking room acoustics, monitoring workplace noise, or just curious about your environment — Sound Meter gives you the data you need. ## Rankings - #2,192,274 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.FOREGROUND_SERVICE_MICROPHONE` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.RECORD_AUDIO` - `android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `com.google.android.gms.permission.AD_ID` - `com.hsh.decibel.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Sound Meter: Decibel Meter](https://chrome-stats.com/d/io.ironframe.soundmeter) — 38 users - [Sound Meter: Decibel Meter](https://chrome-stats.com/d/com.ndtstudio.soundmeter) — 64 users - [Sound Meter](https://chrome-stats.com/d/reze.soundmeter.noisedetector) — 25 users - [Sound Meter: dB Meter](https://chrome-stats.com/d/sound.db.meter) — 53 users - [Sound Meter - Noise Detector](https://chrome-stats.com/d/com.pablosoft.soundmeter) — 177 users - [Sound Meter - Noise Detector](https://chrome-stats.com/d/com.ilyas.ilyasapps.soundmeter) — 38 users - [Sound Meter: Noise & dB Meter](https://chrome-stats.com/d/com.faseeh.ultimatemeter) — 36 users - [Sound Meter Pro - dB Detector](https://chrome-stats.com/d/com.tamizhapps.sound_meter_pro) — 92 users - [Sound Meter](https://chrome-stats.com/d/com.xphygame.sound_meter) — 48 users - [Sound Meter – Decibel Meter](https://chrome-stats.com/d/soundmeter.noisedetector.decibelmeter.soundlevel.infrasound.noise.transmission.meter) — 3,162 users, 2.33 / 5 - [Sound Meter: Live & Record](https://chrome-stats.com/d/com.hyojun.soundmeter) — 141 users - [Sound Meter - Noise Level dB](https://chrome-stats.com/d/com.hampushellqvist.soundmeter) — 119 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.hsh.decibel)
