Decibel X PRO: dBA Noise Meter 9.8.0

Decibel X is a top-notch noise meter app that sets itself apart in the market. With highly reliable, pre-calibrated measurements and support for dBA and dBC, this app is a must-have for professionals and individuals alike.

The success of Decibel X can be attributed to the combination of expertise in sound communication, attentive listening to user feedback, and a clear product vision.

While primarily benefiting audio experts and individuals exposed to noise pollution, Decibel X also adds an element of fun while protecting your hearing. Have you ever wondered about the volume of your environment or the noise level at a rock concert or football match? With Decibel X, you can find answers to all these questions.

Please note that a reading of 0 dBA should not be expected in quiet rooms. The standard usable range is 30-130 dBA, with an average quiet room measuring around 30 dBA. While all devices are pre-calibrated, custom calibration is recommended for precise and accurate purposes. It is advisable to use a real external device or calibrated sound meter as a reference and adjust the trimming calibration accordingly.
