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.)

Perfect for studio
Developer Response ,
Thank you for your positive feedback. It would be great to discuss the way of using the app on studio via support@dbmeterpro.com
This app is a joke
I’m laughing reading the other reviews, this app will read 40-50 dbA, while my room being dead silent.
Developer Response ,
Thank you for your feedback on using Decibel, I appreciate it.
I want to clarify the fact that it is normal to get a 30-40 dB reading even in a very quiet room. This is because there is always background noise, especially if you live in the city. In fact, the only way you can get a 0 dB reading is if you are in an anechoic chamber. You can read more about this here: https://decibelpro.app/blog/why-you-wont-get-a-0-db-sound-level-meter-reading-in-a-quiet-room/
I assure you that the accuracy of the Decibel app is comparable to professional sound level meters and you can trust its readings.
Wish you all the best!
