*"
Wind noise is the value measured by applying a wind velocity of
0 dB =2x 10 "bar
*" The external magnetic field induction noise is measured with the
microphone placed in an alternating magnetic field of 50 Hz, 1 milli-
gauss.
The maximum
noise value is taken and converted
to the equiva-
lent input sound level.
