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) ...

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.

For more information, watch YouTube and visit the blog. Thank you.

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.

Seems good so far. I'm collecting evidence for a noise complaint for knocking in my apartment walls. I like the screen shot function. This is the first time ever in actually considering paying for an app. I'll have to get it calibrated to make an informed decision on it though.

Ads get disruptive to the point making this app useless when you want to urgently measure the noise. At the launch you get a bunch of full screen ads you cannot skip, so by the time you get to the functionality - it's too late. It's like rotating the ads all the time while this app is running wasn't enough, with those full-screen ads you don't get to use the app, but you see the ads instead. Uninstalling this rubbish.
