App Description

The following description comes from the Google Play Store description of the app:

Sound Meter is in the 4th set of the Smart Tools collection.

Have you ever suffered from the noise of the neighbors?
SPL(sound pressure level) meter app uses your embedded microphone to measure noise volume in decibels(db), and shows a reference.

REMEMBER!! Most smartphone microphones are aligned to human voice (300-3400Hz, 40-60dB). Voice calls do not require high-performance microphones.
Therefore the maximum value is LIMITED by manufacturers, and very loud sound(100+ dB) cannot be recognized. Moto G4 (max.94), Galaxy S6 (85dB), Nexus 5 (82dB), HTC Desire(82dB)...

See 6-7th images. I calibrated major android devices with an actual sound meter (dBA). You can trust the result in routine-noise levels (40-70dB). Please use it as an auxiliary tool.

* Main features:
- Upside down mode
- Level notification
- Line-chart duration
- Material design


* Pro version added features:
