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.)
