Decibel X PRO: dBA Noise Meter App Description

"Decibel X" is one of very few noise meter apps on the market that has highly reliable, pre-calibrated measurements and supports dBA, dBC. It turns your iOS device into a professional sound level 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 X" will help you answer all of those. WHAT MAKE IT GREAT AND STAND OUT FROM OTHER APPS: - Trusted accuracy: the app is tested and pre calibrated for all Apple devices. The precision is matching with real SPL devices - Apple Watch support: see noise level right from your wrist - Frequency weighting filters: A, B, C, Z - Powerful, smart history data management: + Recording data can be saved into a list of history records for future access and analysis + Each record can be exported as hi-res PNG graph or CSV text via sharing services + iCloud support which synchronize all history records across your Apple devices + Fullscreen mode to give overview the whole history of an record - 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 with 2 display modes: Rolling & Buffer - InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.). - Support both Portrait and Landscape layouts - Beautiful, intuitive and carefully crafted UI design - Optimized for iOS 11 OTHER GREAT FEATURES: - Standard time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds) - Trimming calibration from -15 dB to 15 dB - Standard measurement range from 30 dBA up 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 layouts - Quick reference text to help you compare with real-life examples - "Keep Device Stay Awake" option for long duration recording - Reset and clear current recording 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. - 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.

  • Take picture but no video ??

    It seems like a common sense idea for a DB app to take pictures of what your metering with the results overlaid, but why not add the ability to overlay a video ??

    App usually closes on its own after about 3 seconds - no value there. App support does not work.
  • Works as advertised

    Apps should work as intended. The science and tech in this one does. I haven’t had the equipment to test or adjust its accuracy but it appears to be correct out of the box. I recommend it.
  • Awful. Will ask for refund. The ad are NOT accurate to what the Pro version does :((

    I occasionally need to monitor noise levels at home or in classrooms when I’m substitute teaching. So I’m a novice at this, although I am a scientist in other areas. This APP does everything I need: records noise levels, lets me adjust the parameters, such maximum acceptable noise level, and I can download the data. It defines & explains everything. It is calibrated. The only thing it has no effect on is my 4 cats’ level of meowing. If only it could feed them.... I’m thrilled with this APP!

    The app will freeze when trying to save the current sound measurement. Look elsewhere for a reliable sound monitoring app.
  • Nice App

    The Apple Watch version worked. Now it doesn’t. Just displays zero. Can you fix? Thanks
