Processor Features in ELF
Feature Description
Background Noise Intended to reduce background noise
Reduction without reducing speech levels.
Impulse Noise Designed to reduce gain in the
Reduction presence of sudden, loud noises.
Wind Reduction Designed to reduce the noise
produced when wind is detected over
the Processor microphones.
Directional Mode The behavior of the microphones for a
given program.
Feedback Intended to prevent squealing of the
Cancellation Processors caused by feedback.
Acclimatization:
Automatic Provides gradual increases to gain
settings over a defined period of time.
Allows professionals to manually
Manual
manage gain settings for quick global
tuning adjustments.
Volume Learning The Processor tracks and remembers
volume control changes made by the
patient and gradually changes the
preferred volume level over time.
-
It is recommended that both
Processors be set to the
same microphone mode
-
Every program features
recommended defaults that
may be modified
Options
Off, mild, moderate, strong
Off, On
Off, mild, moderate, strong
•
Omni- amplifies sound equally from all
directions
•
Fixed- sounds coming from the front are
amplified and sounds from the back are
attenuated
•
Automatic adaptive- designed to actively
steer the microphones away from the
loudest noise source
•
Automatic fixed- automatically switches
from Omni to Fixed mode when noise is
detected
•
Off, Slow, Fast
When enabled, the following parameters can
be set:
•
Duration: the amount of time it takes to
progress from one level to the next.
Options include 1, 2, 3 and 4 weeks
•
Starting Level: 70, 80, 90% from the
targeted response
•
Frequency range affected: acclimatization
can occur for the entire frequency
response or for the frequencies only
(>5kHz)
•
Gain to Target off-sets options include 70,
80, 90 and 100%
•
Frequency range affected: acclimatization
can occur for the entire frequency
response or for the frequencies only
(>5kHz)
•
Off (default), On
