Powered by real-time audio analysis and an interface you can read at a glance, Decibel Meter transforms your iOS device into a capable sound level meter. Point your phone at the noise and see exactly how many decibels you are dealing with - no setup, no account, no internet connection needed. Key Features Real-Time Decibel Readings A large, instantly readable dB value backed by a live graph of the last two minutes, so you see not just how loud it is right now, but how it has been changing. (Premium subscription required.) Professional A, C and Z Frequency Weighting Switch between the IEC 61672 weighting curves the professionals use. A-weighting matches human hearing and drives most noise limits, C keeps the bass for music and machinery, Z is completely flat. Fast (125 ms) and Slow (1 s) response speeds included. (Premium subscription required.) Min, Average, Max and Peak Statistics Every session tracks the quietest and loudest moments, the true energy average (Leq) and the unsmoothed peak, so you can describe any environment with real numbers instead of opinions. (Premium subscription required.) Noise Dose Tracking See your exposure as a percentage of the recommended daily limit, based on the NIOSH standard of 85 dB over 8 hours with a 3 dB exchange rate. Know when it is time to walk away. (Premium subscription required.) Camera Mode with Live dB Overlay Put the decibel readout on top of what your camera sees and record it as a video clip - perfect for showing what was loud, not just saying it was. (Premium subscription required.) Saved Records with Location Tags Name each measurement, tag it with the place it was taken, and open it again later with the full graph and statistics intact. (Premium subscription required.) Manual Calibration Match the app to a reference meter once, and the correction is applied to every measurement from then on. (Premium subscription required.)
