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.

Decibel X PRO: dBA Noise Meter App Reviews

  • Frequent Crashes

    By Keith80
    Spent around $8 for the pro version, and it crashes all the time.
  • Good but

    By Love and frustration
    For my iPad going full screen does not give the full bar and details I like to see in portrait mode. Having that option for landscape view would be appreciated.
  • Great

    By Scogmo
    My slow WiFi up in the woods didn’t download all the features on iPad at first, weird. When I drove to town my iPhone got the recording data features and when I got home they were on the iPad too. So ignore my 4 star review wishing they had more features. :-)
  • Won’t work.

    Application constantly shuts itself off. Very disappointed.
  • The delete function for a single report does not work

    By mira100000
    It was a good app until the function of seeing the report horizontally was removed. In addition, when you delete one report then close the app, that report comes back.
  • Real volume feedback

    By Scottkins81
    This app allows me to give real time feedback to my students on their volume level during a performance. I like that I can take a photo and attach it to their assignment as proof.
  • Camera mode crashes the app... FYI

    By MusicalMyers
    I’m a music and Theatre teacher, and just attended a conference, one session was on the need for hearing protection for music teachers. I panicked, bought some cheaper earplugs for the time being, set an audiology appointment, and purchased this app. I’ve only played with the app, for a few minutes and noticed that on the camera setting the app crashes. Seems like the developer is very responsive though, and is why I went through purchasing the app. Fyi: I’ve played on my piano for just a few minutes and was shocked that I can easily push my piano about 95 decibels! Yikes! Guess, I’m glad I purchased the ear plugs... and the app.
  • New update = Fixed

    By Crazyguy™
    Developers seem to care and fix issues quickly
  • Modern Dark theme crashes App

    By Philip Levin
    For those wondering, if you had the modern dark theme enabled, your app will crash. A temporary fix to this would be to redownload the app and leave the classic theme on. Until the developer comes to fix this, we will be stuck with this for now.
  • Dissatisfy

    By Jrwyjr
    App stopped working! Don’t waste your money.
