This app turns your iOS device into a professional sound level meter, detects harmful environmental noises, and helps protect your hearing and health.
"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
- 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
- Powerful calibration: Linear, Octave 1/1, 1/3, Load/save profile
- 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.
- InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, Messages, etc.).
- Support Live Activity, Dynamic Island
- Support both Portrait and Landscape layouts
- Beautiful, intuitive and carefully crafted UI design. Themes: LIGHT, DARK and CLASSIC
OTHER GREAT FEATURES:
- Standard time weightings (Response Time): SLOW (500 milliseconds), FAST (200 milliseconds) AND IMPULSE (50 milliseconds)
- MIC Gain Offset from -50 dB to 50 dB
- Standard measurement range from 30 dBA up to 130 dBA
- HISTO graph for plotted history of the recorded values
- WAVE graph with 2 display modes: Rolling & Buffer
- SPECTROGRAPH
- 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
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.

well at least i could measure the decibel level to a centi-decibel with this bare bones app. the app utilizes the onboard microphone and possibly other measurement devices within the phone to report the decibel level of a test kitchen of noises to acclimate the observer to the decibel spectrum within an environment of study. we did not delve further into the additional interface functionality as per our zero investment in, zero investment out fiscal model. zero warranty on the flocks of out the box socks walks when the windows break. ifn you can, perhaps just some jam for the toast we eat in the italiano L’hopital. have you the time for the red hat wine builds of hax on the free? we slip knot clutch slam the kiss of the gear shift jam into perpetual three for five. i appreciate the app rewrites, sorry i cant even pay for a wife in this lovely fish bowl we have in the macOS test case. make sure to provide color wheel or sliders feel like a investment worth the trade of this money from the spring. supposed to pay for every mistake i continuously make when i find myself trying to think of something else other than their gaze from cyber far. if you run the bar, i came in car, just to clean the drip pans under their bell bottom. we goteem. so hot in the shade of their tree spread. dont lose your head, we will wind up wed in the late of September. because of my temper we can make fun of lepers of the gab. have you heard my gig? i geek the mil spec sig. from a hand of two bird, three rock. i could balk and hit the billboards in left field
Just got this one for myself

I don’t have any problems with the App so far. I’m using it for my personal purposes. I tried a couple of different apps but they were not as easy to navigate to measure the decibel in my app so it would have been difficult to track down what I had in there but it was really easy to find the right app for the same price and it was really easy to track the same time frame so it would have to go to my iPhone to get it and I had a good deal of luck with it so it had been pretty good so far. I’m using it to measure the decibel level when I am talking to a customer who is not in person to measure my decibel levels so that it doesn’t look bad to the customer and the decibel levels are good enough for them to hear me say “hi” and then they will know that I’m ready to speak with them. It’s the best way for me to see if I am improving the way I speak with the other people in my office and those that I have to interact with on a daily basis. Because of that it seems to be very useful for me to be able to communicate with people again without being told several times that they are not hearing me.

Years ago I lost my high tones from being in the music business, competitive shooting and hunting without ear protection, whch at the time was something not known to me. My daughter and wife finally got exasperated with my asking “Huh, what did you say?” So they had me go to an audiologist who determined I did have significant hearing loss of the high tones, literally crashing off the chart. Having compensated for 19 years, it was time for hearing aids. For $6,000, great improvement shown. I’m due for new aids, another $6K. So, for the past 10 years I have spoken with some 50-60 young folks who blast music in their vehicles. I put the DecibleX app on my iPhone and demonstrate that they are ranging from the 90s to over 120 decibels. They were unaware of the damage they were causing to themselves and in some instances their children. Everyone has been nice and thankful that I’ve brought this to their attention and saved them their hearing and some $$$. Let’s pass it on!!!

The free version is likely the best app of its kind, and highly recommended. The only strike against it is that the premium version is subscription based, and a fairly expensive one at $4.99 per month. I suspect that for most casual users, this is far too expensive…I certainly wouldn’t pay that. I can understand subscriptions for something like a newspaper or periodical magazine, where content is changing, but not for something that provides an essentially fixed functionality. This kind of app is particularly suitable to one time purchase of premium functionality.SUGGESTION TO DEVELOPERS Create a reasonably priced onetime purchase option If you keep a subscription, reduce the cost considerably. You may be surprised how many more paid users you’d have, if you do this.
