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.

Ratings and reviews

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.

Super intuitive and easy to use! I love the little scale of example sounds for different sound levels, which is crazy helpful for people who don't have a lot of knowledge for what the numbers mean

The app works well however the limitation here lies within the cheap microphone and software used on most cell phones. But good job guys I'm impressed.
