[QUOTE="Timber_MG, post: 547685, member: 18"] Guys, mobile phones don't have a noise floor low enough to measure so low and they are in no way calibrated. Even typical measurement mics DIYers use like the UMIK-1 or Behringer ECM-8000 have a self-noise floor in the 30s often. To measure on the order of 20dB and have any confidence in the measurement you need a 1/2" mic capsule (typical SPL meter) or something better in a 1/4" like Earthworks. [/QUOTE]
