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
- 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

- 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.

Very useful tool for initial setup and monitoring!

It’s ok

Ben3729 on

United States

It’s ok but the watch app is very laggy and inaccurate

Elaborate app, developer MIA

jd2020 on

United States

Amazingly robust app. But it’s offered in both subscription and paid version. It’s too difficult to figure out the differences (e.g. onetime payment is less than the subscription?). The developer didn’t reply to requests for help.

OK

Great app

Delawareteacher on

United States

I downloaded this during a Phillies Orioles game at Camden Yards. First- mothers bringing babies into this stadium should know the decibels when the Orioles hit home runs are too loud for infants. It was easy to download and fun to see how loud the crowd cheers

Great App

Paul Sukhu on

United States

It would be even better if it supported landscape mode on iPad.

Spying with microphone.

Audio Oddities on

United States

Pretty sure this company is spying on people. Every time I grab my phone that app would be open, listening, even though I did not open the app , but it would open by itself and be on every time I turn my phone on. Shady. I deleted it.
