Decibel X PRO: dBA Noise Meter App Description

"Decibel X PRO" is one of very few sound meter apps on the market that has highly reliable, pre-calibrated measurements and supports frequency weightings: ITU-R 468, A and C. It turns your iOS device into a professional 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 X PRO" 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: ITU-R 468, 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 - Dosimeter with NIOSH, OSHA standards - 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.

    Crashes way too often. Paid 4.99 for the pro hoping that would resolve the issue but it didn’t.
  • Added video

    Brilliant and thanks for adding the ability to take a video with the dB overlaid, would it be possible to take landscape videos in the next version ?? :-) I do though wonder if the majority of people who use this app realize the value of being able to take a video with the DB overlaid.
  • Excellent

    I’m very pleased with this app. I have one small suggestion: I would like to see the app start in Pause mode instead of Record, or perhaps offer this as an option. Thanks!
  • Worth it! Good App!

    Don't have much experience with this but the app does what we need it to & does it well to check volume inside our haunted attractions.
  • Works and Looks Great on iPhone XS Max

    Time to change my rating: The latest update fixed the App and it’s now working as it used to on the iPhone XS Max and iOS 12.0.1. Great App! Old Review: Decibel X Pro does not display properly or work on iOS 12 on the iPhone XS Max. Hopefully, an update is not too far off! My rating will change if or when corrected.
  • Now fixed on iOS 12 & iPhone Xs!

    [Update: latest version now works as expected—thanks!] Opens to the graph completely full screen with no controls. Labels much too small to be read. Request for help from developer unanswered. In other words, a total waste of money. Caveat emptor.
  • Meter option not presented

    I have tried to install this app several times on my iPhone X’s and all I am presented are the 4 histogram views. I do not see the meter presentation as shown in the examples. Looks like a great app if I could see the meter option and other documentation which is supposed to be part of the application
  • App UI does not display

    Purchased on an iPhone XS Max. The UI from the example images does not display. App frequently crashes. It does show a decibel readout but the font is tiny and difficult to read, and functionality is very limited. I have emailed support twice since last week with no response. Very disappointed and do not recommend.
