Advanced features
Advanced features are prescribed per program and can be modified from their default
settings selecting from the drop down box or by moving the slider to the desired value.
The defaults are set based on the program environment which is selected in the program
tab.
Directionality
All Access Directionality*: automatically adjusts directional microphone patterns to put clients in the best
position to hear what’s important and still monitor the sounds around them. By allowing clients to access
more sounds than other hearing aids, it lets their brains classify what is important, not their hearing aids.
M&RIE* (Microphone & Receiver-In-Ear): combines the two traditional microphones with a third that sits
discreetly inside the ear canal as an integrated part of the receiver module. It uses the unique shape of
the ear to collect sound the way nature intended. The result is an immersive and individualised hearing
experience with greater direction and depth.
Ultra Focus*: In particular situations, the user may want an extra boost in order to only listen to a talker
directly in front. The user-controlled Ultra Focus uses a powerful directional pattern to focus on the
person in front of your clients in very noisy environments. By uniquely using the speech frequencies for
targeted directionality and the high and low frequencies to monitor the environment, they can hear
speech and still maintain spatial cues from around them.
Spatial Sense: An omnidirectional microphone response which mimics the human ear’s natural response
to sound, which preserves spatial cues and helps with the localisation 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 aid(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 aid model selected and the
degree of low-frequency hearing loss. If the user is still experiencing diculty hearting in noise increasing the
directional mix may help.

the feature. Some

DFS Ultra III*
This is the feedback control. It is activated when the devices have been calibrated for DFS Ultra. 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 user 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 7 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 user is reporting
specific issues such as hearing conversation in restaurants, for example, the fitter 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 personalisation. 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 we
viewed on the screen.

11
Impulse Noise Reduction
Sudden impulse sounds can be quite uncomfortable for those using hearing aids. Impulse Noise Reduction
detects the loud impulse sound and attenuate 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 user
is experiencing too much wind noise, increase the setting to a stronger level. If the user 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 aid has been
calibrated for DFS Ultra III. Once DFS Ultra III has been calibrated, this setting is hidden, and cannot be
reselected unless the hearing aid has been restored to factory settings. Auto DFS is designed for use when a
user is unable to return to the clinic for the fitting, and the hearing aid is instead shipped to the user from the
fitter. It can be turned o if the fitter does not believe the user will need any feedback control, in the case of
very low gain settings. It applies a mild level of feedback cancellation, but as it has not been calibrated for the
user’s ear, it may not be as eective at controlling feedback as a Mild setting of DFS Ultra III.
Sound Shaper
Sound Shaper applies proportional frequency compression to the fitting. Higher frequencies are lowered to
a more usable or audible range for the user. As user candidacy criteria for the use of frequency lowering is
based on many factors, the default setting is O. However, if the fitter perceives the user 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. Not oered in M&RIE (MM) fittings.
Low Frequency Boost
Should a user with fit with a UP 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.

12
Phone Accessories
Features related to the streamed sound from a ReSound 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 and Noise Tracker II 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
aids will optimise and synchronise the Environmental Optimizer settings for a binaural fitting. If a user
experiences diculty in a particular listening environment adjust the sliders to assign environment
specific gains and noise reduction without requiring a manual program change.
