Complete decibel information. Decibel Meter Pro tracks the noise level, showing a graph of increases and decreases.
Record volume levels. Record volume levels for future reference. The app even geotags your recordings.
Comprehensive spectrum analyzer. If you rotate your device, you get a complete spectrum analyzer that you can configure to report and record data however you need it.
What is it about?
Decibel Meter Pro is easy enough to use for simple tasks, but it's also feature-rich enough to take the place of expensive decibel meters. You can maintain a running measurement, watching sound levels fluctuate. The app keeps up with changes in volume, letting you know when a particular threshold is exceeded.
For those who...
- want to protect their hearing
- need to measure sound levels but don't want to purchase expensive equipment
Not for those who...
- already have an investment in a professional decibel meter
- don't care about sound levels
Why we love it
What's truly unique about Decibel Meter Pro is the spectrum analyzer. If you turn your iPhone into landscape mode, the spectrum analyzer expands to fill the screen and you get more options. You can change the graph, adjust how it records various sound levels, and get much more information about the sound levels. This is a free app, but it does have certain limitations. Some users in the past have complained about the pop-up ad to purchase the unlimited version came up too often, but I only saw the message once every 15 to 20 minutes. That's pretty reasonable for an app as fully-featured as this one is.
Decibel is FREE but there are more add-ons
App Store Description
Decibel Meter Pro 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.
(Please note that dB Meter Pro app is not a replacement for professional devices and should be used for personal purposes only.)
