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.

This software is a must for sound engineer, to cut off any unwanted input signals to mixer, we can blocked and just accordingly without trial and error. With this apps, we can saw which signals is over and over the border band on Low and High.Mid signal also can be managed too.Just saw the graph and back to your basic physic engineering book.

The app itself is good (hence why at least 2 stars) and truthfully I’d only considered it for a single use case (ie. did not intend to use this regularly) and I’d only considered this one because of the free trial… only to see that they charged me the S$8.98 monthly subscription *the same day* as the free trial started. Which I only discovered 2 days later. And was unable to claim a refund. Whether it’s intended to be malicious or not, I can’t say but that’s a terrible way to gain customer trust.

Hi, gitcleanslate! Thank you for your feedback. If you only use our standard features, the app is totally free. In case, you want to use our premium features, you have 3-day-trial then update to our subscription package accordingly. You can unsubscribe anytime by following Apple Store instructions.
Nice in theory, terrible execution.

Looks nice on the app if you want to play. But if you want to do some serious data analysis it is terrible. Exporting in CSVs is supposed to keep data such as date and time, and its not even accurate. It shows some default date/time rather than the actual recorded one. It also doesn’t allow exporting the histograms and octave band charts. Very limited capabilities for a paid app. The subscription is completely not worth the money. Glad I didn’t pay for a year in advance.
This is the best
Cheese destroyer is a beast
It was so funny recording my best friends talking so loud and it’s funny for me good app in fact best app for tracking decibels
