(Note: Hardware microphones in most mobile devices are tuned to human voice frequencies. Extreme loud sounds over 90-100 dB may be limited by your device's hardware AGC. Our software boost helps, but for industrial precision, a dedicated SPL meter is recommended.) ## Rankings - #1,984,997 — 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.INTERNET` - `android.permission.MODIFY_AUDIO_SETTINGS` - `android.permission.RECORD_AUDIO` - `android.permission.WAKE_LOCK` - `com.android.vending.CHECK_LICENSE` - `com.google.android.gms.permission.AD_ID` - `com.redif.soundmeter.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [Sound Meter: Noise & dB AI](https://chrome-stats.com/d/com.unver.sound_meter) — 46 users - [dB Sound Meter: Measure Noise](https://chrome-stats.com/d/com.peachy.soundmeter) — 116 users - [Sound Meter - Noise Detector](https://chrome-stats.com/d/com.tooltoolnam.sound_meter) — 236 users - [Sound Meter: Noise & dB Meter](https://chrome-stats.com/d/com.faseeh.ultimatemeter) — 41 users - [Sound Meter : Decibel Meter](https://chrome-stats.com/d/soundmeter.decibelmeter.noisemeter.dbmeter.sound.level.meter) — 373 users - [Sound Meter App: Decibel Meter](https://chrome-stats.com/d/spl.decibelmeter.soundmeterapp) — 878 users - [Sound Meter - Noise Detector](https://chrome-stats.com/d/com.pablosoft.soundmeter) — 180 users - [Sound Meter Noise Detector Pro](https://chrome-stats.com/d/com.putramobi.noisedetector) — 23 users - [Sound Meter - dB Noise Meter](https://chrome-stats.com/d/com.smartwho.smartsoundmeter) — 7,485 users, 4.00 / 5 - [Sound Meter - Decibel Level](https://chrome-stats.com/d/com.whale.decibel.soundmeter) — 1,163 users - [Sound Meter](https://chrome-stats.com/d/reze.soundmeter.noisedetector) — 42 users - [Sound Meter - Noise Level dB](https://chrome-stats.com/d/com.hampushellqvist.soundmeter) — 122 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.redif.soundmeter)
