Description

The new version 5 has been released with huge improvements. Please refer to the What's new for more details!

-------------------------------------

"Decibel 10th" turns your iOS devices into a professional sound/noise 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 wondered how quiet is your room or how loud is a rock concert or sport event? "Decibel 10th" will help you answer all those right now.

Most importantly, this app is FREE and we commit to regularly improve the tool to maintain its best accuracy and usability for everyone. If you like it or have suggestions, please support us by rating and giving us comments and feedback.

SPECIAL:

- InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.). It should be a lot of fun to let your friends know the noise around you!

FEATURES:

- Tested and calibrated for most Apple devices. The precision is matching with top rated apps and real SPL devices
- Frequency weighting filters: A, B, C, Z
- Time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds)
- Trimming calibration from -15dB to 15dB
- Standard measurement range from 30 to 130 dB(A)
- HISTO graph for plotted history of the recorded values
- 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.
- 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
- "Keep Device Stay Awake" option for long duration recording
- Reset and clear all data at any time
- Tap on Max value to reset at any time
- Pause/Resume the tool at any time
- Beautiful, clean and intuitive UI design
- Apple Watch support

NOTES:

- Please do not expect a quiet room reading will be 0 dB(A). The range 30-130 dB(A) is the standard usable range and an average quiet room will be about 30 dB(A).
- Although all devices are pre-calibrated, custom calibration is suggested for serious purposes requiring higher precision and accuracy. 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.
