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: 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.

App Reviews

  • Simple to use

    By Walter 47
    I like simple to use, not too many bells and whistles
  • Constant crashing iPhone 6S+.

    By Bikeman4u2c
    Very unstable and no fixes.
  • Not accurate - expected more

    By AppleUser2354
    The measurements are inaccurate- the added functionality is remedial for the price. There are much better options, better interface, for the money
  • Great App

    By NickExtras
    Previously wasn’t working but new update made program work again.
  • Very useful

    By patricknss
    Great to have in order to understand level of noise environment. Proves a device to evaluate various noise levels of products being considered for purchase
  • Failure

    By wrench_force
    App usually closes on its own after about 3 seconds - no value there. App support does not work. Support appears not to exist.
  • Proved my point

    By Kerrybatdog
    I got this app to measure noise from my upstairs neighbors to prove to management how loud they are. Did exactly what I needed it to do! Now I’m a bit obsessed and often find myself measuring the dB levels around me. Great little app.
  • Need NC rating

    By Gun Buddy
    I have been looking for an app that can provide the NC rating of a space. This app does everything else really well
  • So Easy!!

    By Leven B.
    Very accurate!!
  • Take picture but no video ??

    By Bekuz_Ikan
    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 ??
