* Wind noise is the value measured by applying a
wind velocity of 2 m/s (6.6 ft/s) from all directions
to the microphone. the mean value is taken and
converted to the equivalent sound pressure level
(0 dB =
20
µ
Pa).
**External magnetic field induction noise is measure
with the microphone placed in an alternating
magnetic field of 50 Hz, 1 mG. The maximum noise
value is taken and then converted to the equivalent
sound pressure level (0 dB =
20
µ
Pa).
Design and specifications are subject to change
without notice.
