With dB Volume you turn your iPhone into a Sound Pressure Level (SPL) Meter.
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!

Je voulais mesurer si la balance dans mon casque etait ok, j'ai pu la regler au db pres. Pour avoir le spectre, et des analyses frequentielles, il faut acheter la version +, normal ;)
