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.

Really Nice; How About This.
This is a great tool for audio enthusiast and semi pro apps.. very useful. How about this developer... what if you had a filter for the audio enthusiast that instead of showing air plane, riveter, streets noise, etc, it showed whispering, quiet conversation, normal conversation, public speaking, quiet church music, typical church music, loud church music, Jazz, Orchestra, Country Music Concert, Rap Music, Rock Concert. Each of these have associated typical levels such as...
60~67 Quiet Conversation
67~70 Normal Conversation
70~72 Public Speaking
82~92 Quiet Church Music
92~95 Typical Church Music
95~102 Loud Church Music
115~125 Rock Concert
Etc... you get the idea
These are all subject to I individual styles and preferences but the ideas is to get close, some type of base line for people who really have no idea what they’re doing but they knobs anyway (and you know who you are). This is very common in church music and small clubs where speakers mics are either so soft people lose interest or so loud it’s annoying. Or when the band is so soft it ruins the mood or so loud it’s dangerous to your ears. Many churches have no idea what is appropriate sound levels or what is borderline dangerous. I think this might be very helpful.

Very Good, With One Quibble...
I’ve used a couple sound meter apps over the last few years along with a commercial quality sound level meter. I would put this up there with the best of what I’ve used. This review is for the purchased, “pro” version of the software. That I can pay $4.99 and use the processing capabilities of my iPhone in leu of spending $150+ on a professional, stand-alone meter blows my mind.
The level of detail shown in the various portions of the screen offer a broad range of information to the user. You get both numerical and graph output as well as dial analog output of minimum and maximum readings, duration, etc.
One quibble is that when I pause the meter and reset it, it asks if I really want to, which is okay, but immediately restarts the sound reading, even if I don’t want it to. Also, I’d like for a reset to take the meter back to “0”. It restarts at the prior average. I would like to see these twin issues corrected, and I’d then give the app 5 stars.

Misleading app name, free version measures dBZ only
The app name is dB, dBA Noise Meter but what the developer doesn't tell us is that the app only reads Z-weighted decibels (dBZ) and not A-weighted decibels (dBA) in the free version. All the guidelines and standards say to measure noise levels in dB(A) as A-weighted decibels correspond to human hearing. So it's really misleading to the public who don't know any better.
dB(Z) levels are typically 10 decibels or more higher than dB(A) so people are always getting the wrong readings, unless they purchase the A-weighted portion. No explanation is provided, it's truly a disservice to people who think they're getting a good reading of their noise environment. Remember, a 3 dB increase in level means double the energy that reaches the ear, so 10 dB at the ear is a huge difference.
Developer should make this information available to the public. They benefit from their top ranking on the app store but forget they are spreading misinformation by not explaining to the public the difference between dBZ and dBA. I will gladly pay $10 for an app that provides readout in A-weighted decibels.

Today we are looking at decibel meter apps to measure noise levels. Do you work in a loud factory and want to see just how much damage is happening to your ears when you “forget” your ear plugs? Maybe you frequent the shooting range and want to see just how loud your new rifle will be before hunting season?
Maybe you work in the mining industry where some equipment can be so loud that when you are in certain areas you have to use inner ear AND ear muff ear plugs. Are you a sound technician for concerts, amateur bands, or your church? Maybe you just like going to concerts and want to know how loud it is where you’re sitting?
Whatever your reason we are sure there are many we have not thought to list here; however we know that there can be endless reasons for wanting to know how loud your immediate environment is.
We are also guessing that you don’t want to spend anywhere from $200 to $3,000 or more on a tool to satisfy your curiosity. With that in mind, here are our picks for the seven best apps to measure noise levels in decibels (dB.)
Sound Meter & Noise Detector
Coming in at number one we really like “Sound Meter & Noise Detector.” This app is excellent at graphing sound while running in the background on your device; all while saving battery since your screen doesn’t have to be on all the time. The only reason this app is listed so low in our top 5 list is the fact that it’s a little overpowering in the ad’s department. If that’s something you can live with then be sure to download and try it today!

Sound Meter – Decibel Meter & Noise Meter
In second place is the “Sound Meter – Decibel meter & Noise meter.” In this app you will find the ability to calibrate, save recordings, and more options that might typically only be available in a pro app. One really unique thing about this app is the fact that you can earn coins by watching a few videos; then you can use those coins to remove ad’s! This is one way to gain a “pro” app without spending any of your hard earned money! Get yours today!

Sound Meter Pro
Next up we have an actual pro app… when this article was written “Sound Meter Pro” was listed lower than the average gas station pop coming in at $1.50. While the low cost would be well worth the ad-free app in itself; this app also shines in that it seems to be very accurate even comparing to professional dB monitoring tools. The app programmer regularly monitors feedback and encourages email to figure out why if something is not working quite right. They also have a blog where they update users of any pertinent information and note the limitations of this app. Be sure to check this app out when you download it today!

Sound Meter – Decibel
Our pick for fourth best dB meter is “Sound Meter – Decibel.” This app has an awesome user interface and several different ways to display the dB’s it is reading. Add to that the abilities to keep the screen on while monitoring, play pause or refresh the recording; the ability to calibrate the device depending on your phone’s hardware and many more options.
Download Db Meter Iphone
What you really have here is a professional level sound meter app with a free price tag. Enjoy when you download it today!

Sound Analyzer App
For our number five pick we have the “Sound Analyzer App.” Really this is packed with so many features that they should be charging… lucky for you and us it’s free! Even beyond the features available the owner is easy to reach for support and is eager to explain how to use certain features in this app. Like a few other apps listed here, this app can be calibrated to the device you are running it on giving you a far more accurate sound meter. Grab yours today!

Decibel – Threshold
Up next, we have Decibel – Threshold. This one is able to easily measure noises with a built-in decibels indicator (dB) in real time. In addition to that, it should show you the reference value for each type of environment as the sound level we are (i.e. this is the sound of a semi truck passing by, or a kettle going off).
This one actually works really well, and should work with most phones. This does require that the phone is at least running Android 5.0.
Download it now:Google Play
Sound Meter Simple
Sound Meter Simple is as simple as it sounds. Load up this app, and the built-in reader is able to show you what the dB level in the room is. It’ll show you noise levels, and warn you as to what’s dangerous and what’s fine.
However, there isn’t an actual reference point, except for on the app description.

Db Meter App Download
Verdict
Db Volume Meter Download Free
Most of the apps listed above have the option to calibrate them to your device. Most people don’t know that the average phone mic is limited to the 30-96 dB range (the human voice being an average of 40-60 db.) Some phone mic’s start higher and end lower. For the most accurate results with any app listed above you need to know your equipment… test it with an actual sound meter and calibrate your chosen app to your individual phone; doing that you can get very accurate results within the capabilities of your phone. One of these app’s may not replace a sound meter completely; but it may be helpful when you don’t want to drag that around! Whichever app you choose above, good luck and we hope it works well for you!
