Less than 5 dB SPL/m gauss
*1 Wind noise is the value measured by
applying a wind velocity of 6.6ft/second from all
directions on the microphone. The mean value is
obtained and converted to the equivalent
input sound level. 0dB = 2x10
*2 The external magnetic field
induction noise is measured by placing
the microphone in an alternating
magnetic field of 50 Hz, 1 m gauss. The
maximum noise value is measured and
then converted to the equivalent input
sound level. 0dB = 2x 10
