What's new in v1.2.1
Noise analyzer app that measures the sound level in decibels in your surroundings. Want to measure how loud or noisy is around you? This is the sound meter application for you.
It has a nice analogue dial with arrow that points to the current decibel sound level where you are. It also has 3 displays, showing you the minimum, average and maximum sound decibels that the app has measured.
Below is a nice real time graph, which shows the current and previous sound and noise level in decibels.
Features:
-Nice graphics, all showing you the sound level in decibels
-Both analogue and digital sound readings
-Minimum, average and maximum measured noise in decibels
-Real-time graph showing you the measured sound values
Note:
Microphones in most devices have a limit, so that readings above that sound limit will not be possible. So, for instance, values above 80 dB in most devices will not be read.

How to install Sound decibel noise meter dB on Android 4.4+
You'll need about 10.9 MB of free space.
- Download the APK — tap Download APK above (5.4 MB). Chrome shows “File might be harmful” for every APK file; choose Download anyway only if you trust this file.
- Open the file — tap the download notification, or open Files › Downloads and tap klb-sound-decibels-meter-15-63646859-0b28ffaf9e002bf43e05ec6efc052d65.apk.
- Allow the install (first time only) — Android 8 and later asks for permission the first time an app opens an APK: tap Settings in the prompt, turn on Allow from this source, then go back. Manual path: Settings › Apps › Special app access › Install unknown apps (on Samsung: Settings › Apps › ⋮ › Special access). On Android 7 and older: Settings › Security › Unknown sources.
- Check the file (optional) — the MD5 of the downloaded file should be 0b28ffaf9e002bf43e05ec6efc052d65. If it differs, the file is damaged or was changed: delete it and download again.
- Tap Install — Android asks “Do you want to install this app?”. If Google Play Protect shows a warning, read it before you continue: the source store rated this file Trusted, but only install apps from sources you trust. If an earlier version is installed, this one only installs as an update when it is signed with the same certificate (SHA-1 shown above).
- Open Sound decibel noise meter dB — tap Open on the install screen, or find it in your app drawer.
Common install problems
- “App not installed” — a version signed with a different certificate, or a newer version, is already installed (Android doesn't allow downgrades). Uninstall it first; back up your data, because uninstalling deletes it.
- “There was a problem parsing the package” — the file is incomplete, or your Android is too old (this version needs Android 4.4+). Download it again, or pick an older version.
- Blocked by Play Protect — Play Protect checks apps from outside the Play Store. Only continue if you trust the source.
