dB Meter & Spectrum Analyzer 9.3

"The best way to meter sound levels" - AppAdvice

Decibel Meter is a feature-rich sound level meter with exceptional accuracy of measurements and an integrated spectrum analyzer. It is calibrated with a professional dB meter.

The world is filled with noise: from cars and power tools to crowds and machinery, there are common sources that produce high levels of noise. Continued exposure to such noise can lead to permanent hearing loss. Sound level meters are essential for those who want to protect their ears from harmful noise levels, but not everyone can afford to spend hundreds of dollars on a professional device.

dB Meter is a free app that provides professional-quality measurement results. It is calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, you can measure ambient noise levels, save your measurements along with their locations, and share them with others. dB Meter offers both utility and stylish design, providing a powerful tool in a sleek package at a fraction of the cost of professional sound level meters.

Please note that dB Meter sound meter app is not a replacement for professional devices and should be used for personal purposes only.
