Weighting
Considerations
The
A
weighting
curve
is
based
on
40
Phon
fletcher
‐
Munson
Equal
Loudness
Contour
.
For
noise
assessments
of
the
effects
of
noise
on
human
hearing,
the
A
weighting
mode
is
recommended.
The
C
weighting
mode
is
recommended
for
machine
sound
monitoring
(steady,
drone
type).
The
Z
weighting
offers
a
linear
signal
response
that
is
not
processed
through
the
meter’s
filter.
Z
weighting
is
suitable
for
monitoring
electrical
signals
(AC
or
DC
signals
for
research
purposes,
for
example).
