Wind
noise is the vaiue measured
by ap-
plying a wind velocity of 2 m/sec. from
all directions
to the microphone.
The
mean
value
is taken
and
converted
to
the equivalent input sound level.

induction
noise
is measured
with
the microphone
placed in an alternating magnetic field of
5OHz,

The
maximum
noise value is taken and the converted to
the equivalent input sound level.
