* 1 A value obtained by converting the average value of noise output generated by a microphone into an equivalent input sound pressure when an airflow of 2 m / sec is applied to each direction of the microphone. (0dB = 2 × 10 −5 Pa)* 2 Equivalent input sound pressure equivalent value of input level that causes 1% waveform distortion at 1kHz when the microphone output signal is 0dB (2 × 10 −5 Pa)
