DFS Ultra™ II
DFS Ultra II combines feedback cancellation and WhistleControl™.
Possible settings are "Off", "Mild", "Moderate", "Strong" and "Music
Mode". Choosing "Off" disables DFS Ultra™ II entirely. The "Mild",
"Moderate", and "Strong" settings are most appropriate for speech
and everyday inputs, and refer to the levels of WhistleControl™
that will be active together with the feedback cancellation.
WhistleControl™ restores gain to the desired response in feedback-
critical situations like phone use. The new "Music Mode" setting
controls feedback while maintaining a truer representation of
music. The default setting for DFS Ultra™ II is "Mild" in every
program except the Music program, in which the default setting is
"Music Mode". If gain increases are made during fine-tuning, or if
intermittent feedback is reported by the patient, the setting should
be changed to "Moderate" or "Strong".
Auto DFS is a new feature option that allows for a standard setting
of DFS to be applied, in certain cases where it is not possible to
calibrate DFS while the patient is wearing the hearing instrument
(e.g., if the hearing instruments are being pre-programmed or the
patient is not present ). Auto DFS is automatically turned 'On'
when the "No" response is chosen for the auto-prompt to calibrate
DFS. Auto DFS can also be turned 'Off' in the "Advanced Features"
section. If DFS has already been calibrated, the Auto DFS options
('On' and 'Off') are automatically grayed out.
Expansion
Expansion options include "Off", "Mild", "Moderate" and "Strong".
These settings are available in all microphone-enabled programs.
NoiseTracker™ II
In ReSound Verso, NoiseTracker™ II is set to be environmentally
dependent for all listening programs except Music. This means that
the degree of noise reduction applied at any moment depends on
the listening environment. NoiseTracker™ II settings include the
traditional "Mild", "Moderate", "Considerable" and "Strong" settings
per program, or the "Per Environment" settings (see "Binaural
Environmental Optimizer™ II" in this guide for further information).
WindGuard
TM
WindGuard
is available in dual-microphone Verso models, and
TM
uses signal processing to reduce wind noise. Available settings
include "Off", "Mild", "Moderate" and "Strong".

Physical Properties
Physical Properties can also be found in "Tools" on the Fit screen.
Dome and tube selection, as well as vent configuration changes
can be made. Apart from record-keeping for the fitting, selections
in this screen affect the display of gains in the Fit screen. For
example, when venting is changed, the amount of roll-off in the
low frequencies will be adjusted to show how this physical change
affects the expected real ear response.
Environmental Optimizer™ II
Another tool in the Fit screen is the Environmental Optimizer™
II. General gain and noise reduction adjustments in a given
program may not be optimal for all types of listening environments
encountered while the listener is in that program. The Environmental
Optimizer™ II allows specific gain and NoiseTracker™ II
adjustments for a possible combination of seven different
environments, ensuring the user receives optimal gain and noise
reduction settings as the acoustic environment changes. If device-
to-device communication is enabled, the hearing instruments will
utilize the ReSound's 2.4 GHz wireless communication to optimize
and synchronize the Environmental Optimizer™ II gain and noise
reduction settings for a binaural fitting.
Every listening situation is accurately classified with
respect to seven different environmental catagories
- the most detailed classification offered by any
manufacturer. The instruments then automatically
adjust gain optimal audibility. And our industry-leading
Noise Tracker™ II sets the most appropriate level of
noise reduction for optimal listening comfort in every
environment.
