Decibel X: dB, 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.

    I have a hearing loss from working on aircraft engines all my life! I am retired now. Everyone says I talk too loud. I can finally see how loud I really am! Thanks for this app!

    The best feature has to be the video recording while displaying the decibel volumes.
  • Surprise subscription

    Apps like this have no reason to require a subscription. Automatically deleted. Will be checking my account tomorrow to make sure I don’t get charged.

    Makes you subscribe, gives you a 3 day free trial but it’s impossible to unsubscribe . The only way to contact them is by sending them an Email and hope they reply. Breaks your privacy , records without permission actively contacts companies and share your information . Don’t instal this App not worth the trouble.
  • A Rip Off Continuing in Progress

    What a novel idea ... set a modest subscription price which starts after a couple days, then provide no evident way to cancel from within the app. Brilliant. Click on Email Support — now why should that have to work, if refunds aren’t going to be issued? App itself is good, but try to cancel...feels like being in a Venus Fly Trap.

  • Constant Crashes

    I really like what this app is trying to do and the presentation of data. That said, the problem is I cannot keep it open for more than a few seconds on my iPhone XR before it vaporizes. It closes without so much as a “fare-thee-well” or an error message. I would actually buy the pro version if the app were stable.
  • Cant play music while using the app

    Huge bug in this app. It tries to hold audio playback focus while only listening.. Either Ads pop up every single time then it crashes. Or Upgrade to professional offer then crash. Useless!
