Getting started

Prior to connecting to ReSound Aventa 3:

1. ReSound devices require a battery when ﬁtting. Make sure the

battery is fresh and that it is inserted correctly.

a. For wireless ﬁttings, insert AirlinkTM/Airlink II in a USB slot on

the ﬁtting PC and wait for the message that new hardware

has been found. Then open ReSound Aventa 3.

b. For wired ﬁttings, ensure that the programming interface

(Speedlink, Hi-PRO or NOAHlink) is connected to the PC

before launching ReSound Aventa 3.

2. Launch ReSound Aventa 3. For new ﬁttings, ReSound Aventa 3

begins in the Start screen, where the patient’s experience with

ampliﬁcation can be selected. Selection of ﬁtting interface and

connection to the hearing aids is done in the upper part of the

Start screen.

Remove the stickers from the size 13 batteries to activate them.

Wait for 2 minutes for best results. Click “Connect” in the center of

the top ribbon of the ReSound Aventa 3 Start screen.

Insert the battery and close the battery door of each hearing

instrument to be programmed, and then click “Connect.”

Choose patient’s

experience level Click “Connect”

This ﬁtting guide gives an overview of how to ﬁt ReSound LiNX2wireless

hearing instruments with ReSound Aventa®3.9. A ReSound LiNX2962

wireless binaural ﬁtting is depicted. Not all features described in this ﬁtting

guide are applicable for LiNX27 and 5 ﬁttings.

ReSound Aventa 3.9 ﬁtting software supports all ReSound instruments built

on the ReSound RangeTM, ReSound Range II and SmartRangeTM chips.

1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 3 10/16/15 9:55 AM

The hearing instruments will appear in the “Select Instruments”

section. When all hearing instruments to be programmed have been

discovered, click on “Beep” to identify each hearing instrument, and

assign it as a right or left device. When each hearing instrument has

been assigned, click “Continue”.

or left ear

A window will appear showing the status of the connection, and will

alert you to recommendations for venting. Choose receiver and vent

conﬁguration as needed. Click “Continue.”

If you have selected “Experienced linear” in the Pre-Fit screen

and you are ﬁtting a UP receiver, you will be prompted to choose

an ampliﬁcation mode. Linear mode provides the same gain for

all input levels and has only one input level control. Semi linear

provides a lower compression ratio than WDRC.

1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 4 10/16/15 9:55 AM

At this point, you may pair ReSound UniteTM accessories by clicking

“Unite Accessories”, or proceed to the ﬁtting by clicking “Continue”.

In this guide, “Continue” is selected.

If ﬁtting a UP receiver, a progress window will alert you to the

capability of the hearing instrument to exceed 132 dB SPL. Click

“Continue.”

Next, a window will appear to prompt calibrating DFS UltraTM II.

Click “Calibrate” to begin the calibration procedure. The progress of

the calibration will be shown. Click “Continue” after calibration is

completed.

Gain adjustment

When the Fit screen is displayed, the hearing instrument gains and

MPOs can be adjusted, and advanced features can be accessed.

Fine-tune the hearing instruments

Safe ﬁtting on

Safe ﬁtting off

Maximum stable gain and Safe Fitting

Once DFS UltraTM II is calibrated, the Fit screen automatically opens

with two shaded grey areas visible on the graph (in most cases).

The darker grey shaded area indicates unavailable gain while the

light grey indicates added maximum stable gain provided by DFS

UltraTM II.

If Safe Fitting is enabled, gain settings will be locked at the dark

grey border. Safe Fitting can be turned off and on in the Fitting

menu or set as a user preference. Note that if you have not

calibrated DFS UltraTM II, there will only be one shaded area which

indicates the full-on gain of the particular hearing instrument.

1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 6 10/16/15 9:55 AM

Program management

The Program tabs are located between the graph and the gain

handles. This is where programs can be reordered, compared,

recalculated, autorelated, copied, pasted, added or removed.

Advanced features

Feature settings are accessed by clicking “Advanced Features”

in the “Tools” menu on the left side of the screen. These feature

settings apply to the currently selected program.

Directionality

Binaural DirectionalityTM II uses 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. The result may be a 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 user with the

optimal combination of speech understanding in noise plus a more

natural sense of surroundings - even in the most difﬁcult listening

situations.

Natural DirectionalityTM II: The Focus and Monitor ears are

prescribed based on the audiogram and any speech audiometry

data that may be available, but this selection can be reversed

through ReSound Aventa®.

Spatial SenseTM mimics the human ear’s natural response to

sound, which preserves spatial cues and helps with the localization

of sound sources.

SoftSwitchingTM seamlessly enables and disables AutoScope/

MultiScope Adaptive Directionality™depending on the listening

environment. The response can be either omnidirectional or

directional, based on the signal-to-noise ratio and direction of

speech in the listening situation.

AutoScope Adaptive DirectionalityTM enables the beam width

to automatically widen or narrow depending on the acoustic

surroundings.

If ear-to-ear is activated, SoftSwitching will ensure that the

microphone responses on both instruments are synchronized.

1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 7 10/16/15 9:55 AM

Directional Mix

The Directional Mix 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.

DFS UltraTM II

The “Mild” settings are most appropriate for speech and everyday

inputs, “Moderate”, and “Strong” are good for feedback-critical

situations like phone use. The “Music Mode” is designed for use in

a “Music” program.

Auto DFS allows for a standard setting of DFS to be applied without

calibration. If DFS has already been calibrated, the Auto DFS

options (“On” and “Off”) are automatically grayed out.

Sound ShaperTM

Sound Shaper is ReSound’s proportional frequency compression

system. Its default setting is “Off.” The recommended setting,

based on the audiogram, is in bold typeface when the menu

options are pulled down.

Low Frequency Boost

If ﬁtting a UP receiver, low Frequency Boost can be applied for

users desiring more gain from 250-1000 Hz. “Low”, “Medium” and

“High” settings will be achieved unless the maximal gain has already

been met at these frequencies.

NoiseTrackerTM II

In NoiseTrackerTM II, the degree of noise reduction applied at any

moment depends on the listening environment. Per environment

noise reduction levels can be customized via Environmental

OptimizerTM II.

WindGuardTM

WindGuardTM uses signal processing to reduce wind noise, and is

available in dual microphone devices.

of crossover frequency

1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 8 10/16/15 9:55 AM

ReSound Aventa®3.9 includes three input level controls at 50,

65 and 80 dB SPL. This allows for greater ﬂexibility for ﬁne-tuning

gains, By default, ReSound Aventa®calculates the gain settings

for the particular audiogram using the Audiogram+ ﬁtting rationale.

Other ﬁtting prescriptions can be selected from the “Fitting” menu.

To ﬁne-tune a program, adjust the gain manually by using the gain

handles or by using the ReSound Aventa®Guide, where ﬁne-tuning

solutions to patient complaints can be automatically applied.

Once ﬁne-tuning is complete, the relative gain changes can be

applied to any or all other programs by clicking the “Autorelate”

button in the program handling tool bar beneath the program tabs.

Select which programs to autorelate to by checking the boxes. You

may choose whether to apply changes made to MPO or Sound

Shaper or compression mode for each program.

Physical properties

Dome type and vent conﬁguration can be changed in Physical

Properties. 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. An option

to (re)calibrate DFS is provided in case the change entered in

Physical Properties accompanies a physical hardware change of

the vent/tube/dome on the hearing instrument.

Environmental OptimizerTM II

Environmental OptimizerTM II allows speciﬁc gain and NoiseTrackerTM

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 Ear-

to-Ear Communication is enabled, the hearing instruments will

optimize and synchronize the Environmental Optimizer II gain and

noise reduction settings for a binaural ﬁtting (Binaural Environmental

OptimizerTM II).

1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 9 10/16/15 9:55 AM

Ear-to-Ear Communication

ReSound LiNX2supports ear-to-ear communication. The master

switch to disable/enable this functionality can be found in the main

menu under “Instrument.” The “Ear-to-Ear Communication” window

keeps a continual record of the enabled Ear-to-Ear features.

Tinnitus Sound Generator

The default setting for Tinnitus Sound Generator (TSG) is off. When

TSG is in the “Standard” mode, TSG options such as noise type,

level, modulation and modulation speed can be changed; when

TSG is in the “Nature Sounds” mode, only sound level can be

changed.

Synchronized Acceptance Manager

Synchronized Acceptance Manager allows for gradual gain

increases from current gains to ﬁnal gains over a speciﬁed amount

of time. Synchronization of this feature is recommended in case of

a loss of one hearing instrument during the acclimatization time, as

this will prevent the remaining hearing instrument from progressing

more than 10% past the progression of the lost hearing instrument,

in the event it is found. Once activated, the Acceptance Manager

progress will appear on the Fit screen. Final gain levels will appear

as dotted lines. To set a ﬁnal level different than current gain

prescription, ensure the box above the gain handles indicates “End

Gains (B).” Select the gain handles desired and ﬁne tune the gains

to the desired levels.

Beeps and Volume Control

The “Beeps and Volume Control” window has two tabs: Standard

Beeps and Manual Controls. In the Standard Beeps tab, all the

acoustic indicators can be demonstrated, changed, added and

removed. Low or high frequency beeps can also be selected. The

Manual Controls tab contains options such as customizing push

button function, enabling and disabling the program button and

adjusting the volume control range.

1510_LN2_FittingGuide_MK604304_rB_8.5x11.indd 10 10/16/15 9:55 AM

Manage accessories

The functionality for managing connectivity to Bluetooth®Smart

devices and ReSound UniteTM accessories can be accessed both

from the Pre-Fit and the Fit screens.

To pair ReSound Unite accessories with the hearing instruments,

click “Add” and follow the instructions on the screen to put the

selected accessory in pairing mode. Accessory pairing can also be

achieved outside of ReSound Aventa®, with the hearing instruments

and the accessory alone.

Bluetooth Smart-enabled devices

Up to 5 Bluetooth Smart-enabled devices can be paired to the

hearing instruments, but pairing must occur outside of ReSound

Aventa.

Saving and completing the ﬁtting

Once the ﬁtting is complete, click “Save” at the bottom right

of the Fit or Summary screens. Once the data is saved to the

instruments and to the database, it is safe to disconnect the hearing

instrument(s).

Summary screen

The Summary screen allows the clinician to print information for

the patient, a third party, or for chart notes. Notes can be entered,

saved and printed as needed.
