  • Automated equalization of microphones
    Patent number: 9813830
    Abstract: An automated microphone calibration starts with reference microphone calibration. Measurements are scaled to sound pressure levels (SPLs). The reference microphone is positioned close to the internal microphones and their frequency responses are measured. Then delta calculation is done in selected sub-bands including reference microphone correction and then a correction filter is defined.
