Advanced features
Advanced feature settings can be modified by selecting the appropriate drop down menu
or by moving the slider to the desired level. These feature settings apply only to the
currently selected program.
Directionality
Binaural Directionality III: Leverages ReSound’s 2.4 GHz wireless technology to allow the hearing
instruments to work together, dynamically selecting the best microphone response for the listening
environment. Possible configurations are bilateral omnidirectional, bilateral directional or an asymmetric
omnidirectional and directional response, depending on the analysis of speech and noise detectors from
both hearing instruments. This provides the optimal combination of speech understanding in noise plus a
more natural sense of surroundings.
Natural Directionality II: The Focus (directional) ear and Monitor (omnidirectional) ear are prescribed
based on the audiogram and any speech audiometry data that may be available.
Spatial Sense: An omnidirectional microphone response which mimics the human ear’s natural response
to sound, which preserves spatial cues and helps with the localization of sound sources.
Soft Switching: Seamlessly enables and disables AutoScope/MultiScope Adaptive Directionality™
depending on the listening environment. The response can be either omnidirectional or directional, based
on whether noise is present and the direction of speech in the listening situation.
Auto Scope: Adaptive Directionality enables the beam width to automatically widen or narrow depending
on the acoustic surroundings.
Directional Mix
All directional microphone modes have both omnidirectional and directional processing through the
frequency spectrum. The setting determines the degree of directionality in the output of the hearing
instrument(s). Directional Mix applies omnidirectional processing below a crossover frequency and
directional processing above that frequency. The default setting is prescribed depending on the hearing
instrument model selected and the degree of low frequency hearing loss. If the patient is still experiencing
diculty hearing in noise increasing the directional mix may help.
Note: Click the
information icons for
a short explanation
of the feature. Some
information text
may be clickable and

DFS Ultra II
This is the feedback control. It is activated when the devices have been calibrated for DFS Ultra II. The default
setting is Mild. Adjust the setting to a stronger level (Moderate or Strong) if concerns for feedback arise. The
Music Mode setting is a Mild setting, typically used for music programs or if the patient experiences feedback
only when tonal sounds occur (for example, from a musical instrument).
Noise Tracker II
Noise Tracker II noise reduction uses spectral subtraction to reduce noise between words and syllables in
many real-world noisy environments. The Per Environment setting allows for personalized noise reduction
settings in seven environments. The environments include Quiet, Soft Speech, Loud Speech, Moderate
Speech in Noise, Loud Speech in Noise, Moderate Noise and Loud Noise, and classification is performed
on a continuum if the listening situation has characteristics of more than one listening environment. If a
patient is reporting specific issues such as hearing conversation in restaurants, for example, the hearing
care professional can precisely increase the Noise Tracker II setting only for restaurant-like environments,
including Moderate Speech in Noise or Loud Speech in Noise. This maintains the setting for other
environments, permitting a great amount of fitting precision and personalization. Alternately, the Mild,
Moderate and Strong settings of Noise Tracker II apply the same level of noise reduction for all listening
environments, when noise is present.
By scrolling down or
pulling up the lower
part of the Advanced
Features screen, all
the features available
for the connected
hearing aid can be
viewed.

Impulse Noise Reduction
Sudden impulse sounds can be uncomfortable for those using hearing instruments. Impulse Noise
Reduction detects the loud impulse sound and attentuates it instantaneously. The feature can be set to
three dierent degrees, with mild as the default setting. Increasing the setting will decrease the threshold
to which the feature will react, or in other words, increase the aggressiveness. Stronger setting will also
increase the amount of attenuation.
Wind Guard
Wind Guard applies noise reduction specifically for windy situations. The default setting is o. If a patient
is experiencing too much wind noise, increase the setting to a stronger level. If the patient experiences the
hearing aid becoming quiet occasionally in outdoor situations, reduce the setting to a milder level.
Auto DFS
Auto DFS is a feedback control setting that is activated automatically before the hearing instrument has
been calibrated for DFS Ultra II. Once DFS Ultra II has been calibrated, this setting is grayed out, and cannot
be reselected unless the hearing instrument has been restored to factory settings. Auto DFS is designed
for use when a patient is unable to return to the clinic for the fitting, and the hearing instrument is instead
shipped to the patient from the hearing care professional. It applies a mild level of feedback cancellation, but
as it has not been calibrated for the patient’s ear, it may not be as eective at controlling feedback as a Mild
setting of DFS Ultra II.
Sound Shaper
Sound Shaper applies proportional frequency compression to the fitting. Higher frequencies are lowered to a
more usable or audible range for the patient. As patient candidacy criteria for the use of frequency lowering
is based on many factors, the default setting is o. However, if the hearing care professional perceives the
patient could benefit from frequency lowering, in the case of continued diculties with speech recognition or
previous success with frequency lowering features, Sound Shaper can be activated.

10
Low Frequency Boost
Should a patient fitted with an Ultra Power device feel that the sound is not full enough or loud enough,
low frequency boost is a quick way to increase the low frequency gain from 250 – 1000Hz.
Phone Accessories
Features related to the streamed sound from a Phone Clip+, or a smart device that is capable of direct
streaming, are located at the lower portion of each environmental program tab. Streamed sound will
inherit the gain settings of the environmental program that is being used during the time of streaming.
While the phone accessory features can be adjusted within the individual program tabs, it is important
to note that settings are applied across programs, therefore phone accessory features changes made
in one program will also be reflected in others. Please note when viewing Data Logging the time spent
streaming from the phone will be collected within the manual program that is being used during
streaming.
Environmental Optimizer II
Environmental Optimizer II allows specific gain adjustments for seven dierent environments, ensuring
the user receives optimal gain and noise reduction settings as the acoustic environment changes.
Classification is performed on a continuum if the listening situation has characteristics of more than
one listening environment. With binaurally fit wireless devices the hearing instruments will optimize
and synchronize the Environmental Optimizer II settings for a binaural fitting. If a patient experiences
diculty in a particular listening environment adjust the sliders to assign environment specific gains
without requiring a manual program change.

11
