"The best way to meter sound levels" - AppAdvice

Decibel Meter is full of features sound level meter with exclusive accuracy of measurements and integrated spectrum analyzer. Calibrated with professional dB meter.

The world is a noisy place: cars, power tools, crowds, machinery, and other common sources produce amounts of noise that can, with continued exposure, lead to permanent hearing loss. Sound level meters are useful for anyone who wants to avoid exposing their ears to harmful noise levels, but who wants to spend hundreds of dollars on one?

dB Meter is free app which provides professional-quality measurement results, calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, you can measure ambient noise levels, save your measurements and their locations, and share your measurements with others. dB Meter couples utility with stylish design and a polished user experience: a powerful tool in a sleek package, and at a tiny fraction of the cost of professional sound level meters.

Great app!

This is an awesome app. I'm an audio engineer for my church but we can't afford SMAART or any of those awesome RTAs. This app is a great substitute. It could use a couple improvements. On the RTA, there's a bar you can use to help you find a frequency, but it doesn't tell you what frequency you're on. It would be awesome if next to the bar it told you what frequency you're on and what the relative dB reading is. Also I do like that the app runs in the background, I just wish it didn't freeze and reset every time I go back into the app. We use Planning Center as well, so I switch back and forth between the apps a lot. Overall, great app that could use a few tweaks to make it better. 4.5/5 stars.

Used product since release

Developers have kept the app updated since 2011 and continue to improve it, clean, beautiful,and simple UI but filled with the information you need to monitor and analyze any acoustic environment I have used it to monitor ambient noise in empty concert halls, classrooms and houses, as well as silly stuff like proving how loud someone snores ;-)

Great app!

I have developed tinnitus over the years and I don't want to make it any worse. So long, in the ear earbuds... I still like to rock out with the great home stereo gear that I have, and this app lets me see at a glance if I'm overdoing it. It's also great to know just how crazy loud it can get in a car. Snow tires increase the interior loudness by a lot... Save your ears! It's worth it.
