The range 30 dBA - 130 dBA is the standard usable range and an average quiet room will be about 30 dBA. Please do not expect a quiet room reading will be 0 dBA. Reset and clear current recording at any time "Keep Device Stay Awake" option for long duration recording
Quick reference text to help you compare with real-life examples Display Current, Average/Leq, and Max values with both nice and clear digital and analog layouts WAVE graph with 2 display modes: Rolling & Buffer HISTO graph for plotted history of the recorded values
Standard measurement range from 30 dBA up to 130 dBA Trimming calibration from -15 dB to 15 dB Standard time weightings (Response Time): SLOW (500 milliseconds) and FAST (200 milliseconds) Beautiful, intuitive and carefully crafted UI design Support both Portrait and Landscape layouts InstaDecibel to capture your dB report overlaid on photos and easily shared via popular social networks (Facebook, Instagram, etc.). + Fullscreen mode to give overview the whole history of an record + Each record can be exported as hi-res PNG graph or CSV text via sharing services + Recording data can be saved into a list of history records for future access and analysis Powerful, smart history data management: Real time predominant frequency is also displayed. Those are very useful for frequency analysis and musical tests. Spectrum analyzer: FFT and BAR graphs to display real time FFT. Frequency weighting filters: ITU-R 468, A, B, C, Z The precision is matching with real SPL devices Trusted accuracy: the app is carefully tested and calibrated for most devices. 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. This extremely useful and beautiful tool will not only be an essential gadget for many uses but also bring you a lot of fun. It turns your phone device into a professional noise meter, precisely measures the sound pressure level (SPL) all around you. "Decibel X" 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.
