About this 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) ...

You can easily check if my voice is loud in a lecture or if the TV volume I turned on is not too loud.
See 6th 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:
- No ads
- Vibrometer
- Statistic menu
- CSV file exporting

* Do you want more tools?
download [Smart Meter Pro] and [Smart Tools] package.

I just now tried a bunch of these, looking for a meter app to help find the correct level that audio should be mixed at, for my recording studio. Sure, I'll calibrate it with an actual meter when I'm finished with renovations but this app is pretty close, if it's not spot on. All the other ones I tried (started from the highest rating down) were way off. They were still only reading 73dB when it was dangerously loud and 43dB when the only noise in the room was a "silent" computer fan.

Using a Pixel 6, this app measured within 1 dB of difference of a professional sound meter setup at ~85 dB. I was quite impressed when I tested it. Also has nice features (like calibration offset, and 180 screen rotation to let you point your microphone and use the app).

Useless. There is not exactly calbrated. NOT ACCURATE!! There are at least 20 db more than the reality. Why there are 41 db measured in a very quiet room with no noise?!
