Sound Meter – Measure noise volume in decibels

[App] Sound Meter

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

Sound Meter user reviews :

Awesome application. I have sensitive hearing, when out and about its great for curiosity’s sake to know the decibel level.

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.

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.

Adds are full-screen and cannot be closed. There is no indication if the SPL level is “A” or “C” weighted, and no way to change it. There is no way to adjust the integratio time for measurements. So basically it is pretty useless.

• Thanks for the comments. This app is designed for casual users. Please use it as a reference only.

Have tried more than a dozen sound level apps. This us about as accurate as any phone app. It’s ads are not as intrusive as most. Calibration is not well documented, but works ok “out of the box”. Am keeping this one.

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.

Love this app, I use it all the time. I had a closed head injury when I was younger so I’m light and sound sensitive. It’s great to have a general idea about the atmosphere sound of a place or event or whatever it may be ahead of time so I can plan accordingly. I’ve used it in so many different environments that I’ve learned the “norms” for many environments.

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).

Not a lot of control over the basic free version, but good response to noise. Levels vary and are not consistent. The calibration resets itself and I’m not sure how to reset it to proper levels other than to reinstall.

Very good and easy to use. Nice images and graphics. I like the callabration features. Only one down side, to reset, you have to exit the app and re-enter it. I don’t know if there is a reset in this app.

• To reset, click the reset button in the lower left corner of the meter, or tap the center of the meter.

Works great. You can pause anytime to review the siund level. Easy to download and use. Some ads that do not really get in your way. Thanks sound meter…
