dB Volume

With dB Volume you turn your iPhone into a Sound Pressure Level (SPL) Meter. You can choose between the industry standard weighting curves and response times. Use dB Volume for measuring environmental noises - it offers now Leq measurement! dB Volume features: - response time modes: impulse, slow, fast - weighting functions: A B C Z (unweighted) - peak hold function - Leq measurement We calibrated dB Volume as carefully as possible for all available devices. But: keep in mind, that due to manufacturing tolerances this calibration does not necessarily apply to your device – it’s still an iPhone and not a calibrated measuring instrument!
