Acquired by setting the AUTO/MAN switch and the ATT switch to “AUTO” and “10dB,” respectively.
*1
Acquired by setting the DIGITAL/ANALOG switch to “DIGITAL.”
*2
Equivalent sound pressure level value converted from the average value of the noise that is output from the microphone when a wind velocity of
2 m/sec. is applied. (0 dB = 2×10 -5 Pa)
*3
Equivalent sound pressure level value converted from the input level value that is acquired when 1% waveform distortion is produced by 1 kHz
output signals from the microphone. (0 dB = 2×10 -5 Pa)
