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

★★ The advanced version (Smart Meter Pro) was newly released. This app (Sound Meter Pro) will continue to be updated, but we strongly recommend that new users purchase the new version. ★★

SPL(sound pressure level) meter app uses your microphone to measure noise volume in decibels(db), and shows a reference. We calibrated a lot of android devices using an actual sound meter with dB(A).

REMEMBER!! Most smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore 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)... You can trust the result in routine-noise levels (40-70dB). Please use it as an auxiliary tool.

Vibrometer uses the phone sensors to measure vibration or an earthquake, and it shows a reference as a seism detector.

The measured values are related to Modified Mercalli Intensity scale (MMI). If it is inaccurate, you can calibrate it so that maximum value is about 10-11. Please use the results only for reference because android devices have a wide variety of performance and sensitivity.

* Pro version added Features:
- No ads
- Sound Meter and Vibrometer are integrated
- Statistic menu (line chart)

Sensitivity is much better than other apps I've tried. Has a much more usable range ability.

I purchased this app many years ago and was displeased when it would not launch recently in an area of no cell coverage.

Skip Irwin, 2023-12-02

A good app for many phones but for the Samsung GALAXY A54 5G it will not register sound beyond 80dB. I refuse to believe the mics are unable to record beyond that.
