Decibel X PRO
"Decibel X PRO" is one of very few sound meter apps on the market that has highly reliable, pre-calibrated measurements and supports frequency weightings: ITU-R 468, A and C. It turns your iOS device into a professional noise 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 PRO" 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- 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 11OTHER 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 timeNOTES:- 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.If you like it or have suggestions, please support us by rating and giving us comments and feedback.
