"Decibel X" is the leading noise meter app on the market, which has highly reliable, pre-calibrated measurements and supports dBA, dBC. Our success lies at the intersection of expertise in sound communication, listening to our dear users, and our vision to build a great product. Our app turns your iOS device into a professional sound level meter, precisely measures the sound pressure level (SPL) all around you. While this pro tool mainly aids audio experts or workers prone to noise pollution, it can also add more fun and protect your hearing. Have you ever wondered how quiet your surroundings are or how loud is a rock concert or football match? "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
– Health App integration: export noise levels directly into Health app.
– 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.

People reviews

Impression and review of people to iPhone App [Decibel X:dB Sound Level Meter]!

  • Unusable without monthly subscription
    by TX.USA on June 26, 2022 at 11:17 pm

    You only get a 3 day trial

  • Not free app… NIOSH is free app from CDC
    by James Firz on June 23, 2022 at 5:38 am

    Careful, I deleted app after trying and then it auto subscribed me… you cant cancel unless 1 day before 3 day renewal… so free to try for 48hrs then auto charges you. Very LAME Apple! “Didn’t you read” you may say… I say “apple, aren’t you about customers?”… what’s up with the 2 day trial then auto enrollment? NIOSH is free app from CDC… I’m using that instead.

  • Accurate
    by Bad B-rad on June 23, 2022 at 1:20 am

    Even compared this meter to a professional one at a large venue, same dB reading. Wow -

  • Only wanted one time use
    by JayBeeEye on June 21, 2022 at 10:07 pm

    Required subscription “purchase” is off putting and sneaky. Advertised as In App Purchases which means free to me. Further the app tells me I’m not registered despite Apple confirming “purchase”. Can’t seem to cancel now. Poor publication.

  • DB App
    by Gregmt621 on June 15, 2022 at 2:33 pm

    Works great!

  • Use at work
    by sound meter on June 13, 2022 at 12:28 pm

    Very useful at work or play

  • Pop ups won’t allow me to exit
    by Rock Solid 15 on June 12, 2022 at 7:53 am

    Pop ups won’t allow me to exit. I got work to do.

  • This app work very well.
    by schlong7 on June 8, 2022 at 1:58 pm

    Of course it’s a 3 day trail period

  • Rubbish
    by Gardea Personal MacBook on June 7, 2022 at 4:18 am

    Save your money and buy literally anything else.

  • dB Meter
    by Rooster#1 on June 6, 2022 at 8:05 pm

    This app found its way on my phone 4 years ago and although it wasn’t the best performing app at the time, I didn’t replace it. It worked adequately for my needs. Today November 2019, the dB Meter is quite improved and I can recommend it to all who have a need for such a device. Basically, a dB phone meter is at the mercy of it’s ability to interact with the mic on the phone. IMO, the makers of this app have sorted this issue. I’m on an iPhone 8 currently.

  • Very useful app for events
    by GreatSc0t on June 5, 2022 at 3:10 pm

    I have a band and also do sound as a hobby in our community. This is a great troubleshooting app. It has always been reliable. I’ve used it for years.

  • Prevent hearing loss
    by Rajannahn on May 25, 2022 at 8:22 am

    Helps when to shut the sound proof windows to reduce road noise from vehicular traffic noise. This may prevent Ear damage and sleep better.

  • Like it!
    by Paul E Martin on May 23, 2022 at 3:02 am

    This seems so accurate and easy to use.

  • Used to be excellent but now…
    by Nickrog97 on May 21, 2022 at 8:38 am

    This app used to be exactly what I wanted, a simple, easy to use decibel meter with different weightings and a visualizer to see the heaviest frequencies. Paid the one time for the full ad free app and went about my time. But just recently when I used the app, it didn’t let me play music at the same time as using the app, meaning I can’t measure the music being played in my car through my phone. I was spammed with messages to upgrade to some $4.99 a month subscription for idk what and to rate the app. So I have now. The dosimeter addition seems really nice but have yet to try it. I’m sure it works great but I paid money for this app and I’m upset I’m being bombarded with messages to pay a subscription.

  • Autobilling is immoral and you know it
    by Kcirtap si enam ym on May 19, 2022 at 12:11 am

    Other than that the app is fine

  • Always crashes
    by sshampton on May 18, 2022 at 1:41 am

    Decent app. Too bad it literally closes every time I try to open it up.

  • Starting use.
    by Acrobatic don on May 17, 2022 at 2:40 pm

    Seems like a promising app. I have asked for help to get started using features. Will report as I learn.

  • No video duration option for iPad
    by Mel Jozsa on May 16, 2022 at 11:18 pm

    I paid for a monthly subscription and the video is still recording as seconds. No video option for longer duration.

  • Looks good
    by Jhhhggffddddffgggh on May 16, 2022 at 2:11 pm

    And easy to use But not very accurate. So it does everything well except the most important thing

  • Great app
    by tbsmil on May 15, 2022 at 10:08 pm

    Works very good.

  • It let me rate it
    by isthisthirtycharactersyet????? on May 10, 2022 at 3:23 pm

    Ur mom

  • Brilliant!
    by morgywn on May 6, 2022 at 10:39 pm

    Perfect app. I have not tested for accuracy, but functionality is phenomenal. Kudos.

  • Like app. Change pricing
    by KabookieP on May 3, 2022 at 10:37 pm

    I am a stereo guy so I use this for my listening volume. I use it often but not a lot of the super advanced features. Because I use it I feel it is right to pay for it but not on a subscription basis. Can there be a one time price option for us less than premium people?

  • Not a free app
    by William Ross on April 26, 2022 at 5:31 pm

    Misleading App Store listing. Unable to run app at all without subscribing to some payment plan. Worthless.

  • It works
    by 1989 tiananmen square massacre on April 22, 2022 at 1:42 am

    It reads the decibels, and the UI looks cool. 12/10 would recommend:

  • The Best
    by Space III on April 20, 2022 at 7:55 pm

    It’s the best noise app out there!

  • So cool
    by magogony on April 18, 2022 at 11:32 pm

    love it everything about this app is so cool so many cool features

  • Requires subscription but doesn’t warn
    by PaintMyCats on April 18, 2022 at 12:12 am

    Only after installing does it say PAY.

  • Sound check
    by huntertl67 on April 14, 2022 at 11:10 pm

    The best way to see what’s going on with your system

  • Good
    by good man 123106 on April 14, 2022 at 2:29 am

    Good

  • Can’t use without immediate payment
    by Ponzored on April 11, 2022 at 2:18 pm

    Just make it a paid app then

  • Subscription
    by unknownjenkins on April 8, 2022 at 4:46 pm

    A subscription for a decibel meter? Extremely greedy. Rather a free one.

  • No free option
    by goooooooface12345 on April 8, 2022 at 2:16 pm

    Asdf

  • Great
    by HeBetterMan on April 1, 2022 at 11:05 pm

    Love it. Saves my ears

  • I hate my friends
    by nsunker on March 21, 2022 at 4:18 pm

    This is how I keep them quiet

  • Bummer
    by LaRoe/Stacey on March 21, 2022 at 3:57 pm

    What did I expect from a cheap app? I hoped it worked. Instead it gave me a one time use and then harasses me to upgrade thereafter-NOT HELPFUL (if you don’t mind paying extras, please don’t mind this review:)

  • Useful and interesting
    by Snowballs on March 20, 2022 at 11:16 pm

    Convenient and accurate for those occasional circumstances when noise or it’s absence becomes noticeable.

  • Sound professional
    by Bummed km on March 19, 2022 at 8:27 pm

    I really like this app. Thanks for making it available. K.M Certified sound engineer.

  • Don't bother, they have a surprise for you.
    by Dddd852 on March 17, 2022 at 3:50 am

    They want you to try it – a free trial! Oh goody! There are way too many accurate tools on the Internet that are free, to ever need this one!

  • How I love Decibels
    by J16_Trader on March 17, 2022 at 3:22 am

    I looooooooove the app because it measures how loud something is

  • Greed at it’s finest
    by DCGoth on March 13, 2022 at 8:04 am

    While the app is usable, the forced subscription model for premium features is a corporate cash grab. I’ve paid a good amount for professional sound software and would have no issue with paying a flat fee to unlock features, as I’ve done with other apps; however, the slow bleeding of the consumer is a joke. If I can’t pay a simple, singular, unlock fee, I’m not interested in being milked on a monthly or yearly basis. It’s not like this app provides updated monthly content, like a Netflix or Showtime app does. It simply unlocks features. Stop trying to cheat your customer base.

  • Did not work
    by nanokelp on March 12, 2022 at 6:34 pm

    Would not progress past initial screen

  • Decibel meter
    by flatsflyer on March 12, 2022 at 12:40 pm

    Very good app.

  • Sound Meter
    by oldtimey man on March 11, 2022 at 11:06 am

    Amazing app😊

  • Good tool for environment noise detection
    by Pggwy on March 9, 2022 at 3:32 pm

    Yep

  • App got me arrested
    by fknfhhyhf on March 7, 2022 at 9:36 pm

    Title says it all. This app is directly responsible for getting me arrested

  • Amp saver
    by LRS71 on March 6, 2022 at 3:01 pm

    I was never impressed with my Denon 5.1 sound. I ran the auto set up multiple times with the small microphone in different viewing areas. After reading an article, I used this app, along with physical distances of each speaker to the viewer. Wow, day and night. Much better surround sound. My understanding is to bring all speakers to an equal level by adjusting the individual dbl of each speaker on the amp, using this app to measure the output. I had to lower the front to match the rear, however you can increase the volume once you are done balancing your system.

  • DBx
    by Stupendouslywonderful on March 5, 2022 at 2:30 pm

    Good

  • Canceled before date and was still charged monthly subscription
    by RayzrzEdge on March 4, 2022 at 7:38 pm

    I canceled before the end of the trial and was still charged

  • Solid app so far
    by Smurdamat2 on March 3, 2022 at 11:52 pm

    Like all the features so far. Is there a way to toggle off and on the definitions of the DB level in the top left corner?
