Ideally the right calibration would be for random incidence but more often you only get 0\u00b0 and 90\u00b0 responses. With a Umik the random incidence is nearly 3dB higher at 20kHz than the 90\u00b0 response. It means that if you use the 90\u00b0 calibration, you are a bit over-correcting and the real response of your loudspeakers is about 1dB lower at 10kHz and 3dB lower at 20kHz. See hereunder corresponding graph from IEC standards. You can see some examples on measurement mics websites such as GRAS or Bruel&amp;Kjaer.<\/p>\n<p>Une mesure peut \u00eatre invalid\u00e9e par certains microphones : la mesure de distortion peut \u00eatre cach\u00e9e dans le bruit de fond intrins\u00e8que \u00e9lev\u00e9 du microphone.
