Descrição:

Decibel Meter Pro is a feature-rich sound level meter that offers precise measurements and an integrated Spectrum Analyzer. It is calibrated with a professional dB meter for accuracy.

In a world filled with noise from various sources such as cars, power tools, crowds, and machinery, it's essential to protect our hearing. Continued exposure to high noise levels can lead to permanent hearing loss. Sound level meters are an effective tool for avoiding harmful noise levels, but they often come with a hefty price tag.

dB Meter is a free app that provides professional-quality measurement results. It has been calibrated using an actual Nor140 high-precision decibel meter. With dB Meter, users can measure ambient noise levels, save their measurements and locations, and even share them with others. This app combines utility with stylish design and provides a polished user experience. It is a powerful tool offered at a 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.)
