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 - 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. * Privacy Policy: http://www.skypaw.com/decibelx/privacy_policy.html * EULA: http://www.skypaw.com/decibelx/terms.html

Easy to use
Easy to use, easy to compare from site to site, and easy to see reductions in noise environment. Great tool.
Very helpful for audio work
I use in my electronics lab and it is very helpful
Interesting, crippled all common/useful features
Most useful features can't be tested without premium subscription. For someone who's learning/playing with settings, at least a trial month would be beneficial, or month-to-month billing option. As a non-pro, not willing to sink that kind of money into an app I may or may not use extensively.
I used it for my baby!
This app was perfect to determine if we were too close to live music. Easy to use. Excellent dashboard. Saved my babies ear drums!! We had to move back because the db level indicated unsafe for 30 minutes sustained. Highly recommend this app!
What a decibel meter!!!
Whoa! I had no idea decibel meters could be this fun!
Great to monitor excessive noises.
Love it. Helps me monitor
True
This a pretty accurate app
Good app.
Interesting and helpful
Excessive noise
A great tool to measure how loud an area is
Funny how the phone distorts audio when recorded l
Today, I measured the sound of my school fire alarm, and it was really funny. I put my phone’s microphone directly next to the microphone, and it recorded a whopping 129 dB! After doing that I saved it as data, and when I listened to it, the output was really loud! Instead of making it sound like a fire alarm, it sounded like static! Decibel X is not only so useful, but it’s also funny! You should use this app to not only measure sound, but make and record funny sounds with this! I would really appreciate to use this for a long time!
