This sound meter is also known as sound level meter, decibel (dB) meter, noise meter, sound pressure level (SPL) meter and to help you measure & detect environmental noise.

Specially "Decibel X" is one of very few sound meter apps on the market having highly reliable and pre-calibrated dBA measurements. It turns your device into a professional sound meter, precisely measures the sound pressure level (SPL) all around you. This extremely useful and beautiful tool will not only be a great tool for many uses but also bring you a lot of fun. Have you ever suffered from the noise of the neighbors? Or how quiet is your room or how loud is a rock concert or sport event? "Decibel X" will help you answer all those right now.

WHAT MAKE IT GREAT AND STAND OUT FROM OTHER APPS:

- Tested and verified accurate on many devices. The precision is matching with real SPL devices when calibrated
- Frequency weighting filters: A, B, C, Z
- Beautiful, intuitive and carefully crafted UI design
- FFT and BAR graphs to display real time FFT. Those are very useful for frequency analysis and musical tests. Real time predominant frequency is also displayed.
- WAVE graph in real time

OTHER GREAT FEATURES:

- Time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds)
- Trimming calibration from -20 dB to 20 dB
- Standard measurement range from 30 to 130 dBA
- HISTO graph for plotted history of the recorded values
- Real time scale level chart
- Display Current, Average/Leq, and Max values with both nice and clear digital and analog layout
- Quick reference text to help you compare with real-life examples
- Record and export the data (up to 24 hours) to email for further analysis
- Reset and clear all data at any time
- Tap on Max value to reset at any time
- Pause/Resume the tool at any time

NOTES:

- Please do not expect a quiet room reading will be 0 dBA. The range 30-130 dBA is the standard usable range and an average quiet room will be about 30 dBA.

- Because there are wide range of devices which have different microphone sensitivity, custom calibration is highly recommend before use. You will need a real external device or calibrated sound meter as a reference, then adjust the trimming calibration until the reading matches with the reference.
