deciBel

For years and years, I've always loved this app, and found it worked better than my $200 dB meter, but since moving to the Nexus 6P, it is completely incorrect. Not sure if there is a developor option to disable the noise cancelling mic?

This appears to be the most accurate loudness meter for Android. I tested a half dozen against a reference device, and after calibration, this one is the closest.

Without the ability to export raw data, this application falls short.

No use

Easy to use.

Works well 60 to 90 on note 3 after calibration

Wow... way better than other sound apps...you can see the frequency coming in...very cool...can read relative decibels easily

I think it's due to the agc built into Android. The app doesn't measure any higher than 90dB.. Nice if there was a way to turn off the automatic gain control for Android's microphone.

Provides the most data while optimizing the simplicity of display of said data. I bet pro version is even better!

Accurate than most of the sound level meter.

good app

what is a maximum SPL level is measured by this app..?? and is this depends on the mic type ?? thank you.

Works well 60 to 90 on note 3 after calibration

Cool! Does what it says.

Doesnt work properly

Wow this is way better than other sound apps...you can see the frequency coming in...very cool...

very close to the real thing

Nice app

Nice

Good accuracy

Not very accurate

Simple and accurate

Put it next to a real tester today and was within .7 of a db.

After calibrating using an instrumentation digital sound level meter and using both the app and the professional meter side by side the results were nearly identical. Comparison made using voice, television and a running vaccum cleaner. Best results of the two apps I downloaded.

Version 1.2 fixes the crash issue on ICS. Useful once calibrated.

Unfortunately this app did not register any readings at all on my moto razr, clearly the microphone was not enabled, and the readings were just stuck at a random default level. It is unfair to give any judgement of it though.

Awesome!

Not accurate

Tried many other ones but this was the best of them all !!

Last minute rush to find a meter, tried 3 other apps which were rubbish for various reasons, this one appeared to work well so used it all weekend, got home and checked it next to a hardware meter and the two were identical - great app : )

I haven't A-B'd them for accuracy. I will get back to you when I do.

Only as accurate as your phone hardware allows.

It was good on my old Moto droid would read max db in my car 140.5 but now on my bionic I can't get any readings over 90 db

I calibrated this at work and for a phone it does well! Will do! for non critical applications!

This is an awesome app! Im into sound and the fact that u can calibrate is top! I havent used it fully yet but i will try it. Few things i would like to see in updates would be maybe an average function where we could set it to say 1 min and it will calculatr the average over that time set. Maybe also a log where u can save highest readings? Thanks for the great app

Works good but make sure you exit the app before making a phone call as it will not let the person hear you...

User-friendly, but was totally wrong at a basketball game. It read 91 db when it really was 120 db. Maybe it was my phone, but there's no way to know.

I have just checked this application against a semi-pro SPL meter and it really is pretty good. I used sinewave tones from 250Hz to 3kHz. I will probably purchase this app.

Used it to get sound level in our datacenter
