*1 The average noise output generated by the microphone when an airflow of 2m/sec is directed in each direction of the microphone, converted into equivalent input sound pressure. (0dB = 2 x 10-5 Pa)
*2 Equivalent input sound pressure converted to the input level at which the microphone output signal produces 1% waveform distortion at 1 kHz (0dB = 2 x 10-5 Pa)
