EXP_slope_Hd 0 for a typical
office

the noise
reduction
algorithm
altogether
The expander threshold for the
headset.
These thresholds correspond to the
maximum amount of expansion that
is applied in the transmit path. These
numbers define the slope of the
expander curve.
Note:
Note:
When Noise
Reduction is
enabled, you can
use the same values
from NR_thresh_Hd
in
EXP_slope_Hd.They
have analogous
meanings. For
example, the NR
numbers refer to
noise reduction
thresholds while the
EXP numbers refer
to the slope of the
expander curve.
NR_thresh_Hd=3
means that there is
no Noise Reduction
and EXP_slope_Hd
means that the slope
is linear (Expander is
off).
