Electro-Acoustic Stimulation (EAS)
EAS is a general term that refers to the simultaneous delivery of electric stimulation (cochlear implant) and acoustic amplification
(hearing aid) to the same ear.
Naída CI Q90 EAS System
The Advanced Bionics Naída CI Q90 EAS system is designed to provide amplification of the low frequencies up to 1600 Hz in combination
with electrical stimulation delivered along the full range of the implanted electrode. The Naída CI Q90 sound processor integrates both the
acoustic and electric sound processing within one device. Fitting of the acoustic and electric parameters of the system is completed within
the SoundWave™ software program in one simplified workflow.
Naída CI Q90 EAS System Components
The Naída CI Q90 EAS system includes the following components:
• Naída CI Q90 sound processor
• Universal Headpiece (UHP)
• Power Source (PowerCel™ battery)
• Naída CI Q90 Acoustic Earhook
• Earpiece (SlimTip or Dome)
Naída CI Q90 Acoustic Earhook
The Naída CI Q90 Acoustic Earhook is required for the delivery of acoustic amplification to the implanted ear. It is connected to the Naída
CI Q90 sound processor and consists of the following parts:
• xReceiver Unit – the speaker is inserted into the ear canal to deliver an
amplified acoustic signal. The Naída CI Q90 Acoustic Earhook uses a Phonak
xP receiver adapted to attach to the Naída CI Q90 sound processor.
• Sound Outlet – where the amplified acoustic signal exits the receiver. It is
important to keep the Sound Outlet clean and clear of wax and debris.
• Retention Hook – may be used to securely maintain the receiver within the
ear canal.
• Retention Hook Guide Dash – illustrates where and how to place the
retention hook on the xReceiver unit. Refer to the guide included with each
Naída CI Q90 Acoustic Earhook for detailed instructions on the removal and
placement of the retention hook on the xReceiver unit.
• Side Indicator – indicates which ear the receiver is designed for, blue for left
and red for right.
The Naída CI Q90 Acoustic Earhook may be ordered in one of five different lengths (00, 0, 1, 2, 3) for either the left or right ear. The
length is noted on the xReceiver unit on the side indicator (ex. 2xP). We have provided you with a measurement tool that you can use to
determine the appropriate length for your patient. Please refer to the guide included with each Naída CI Q90 Acoustic Earhook for detailed
instructions on how to attach the Earhook to the sound processor using the pin removal tool provided.

Naída CI Q90 Acoustic Earhook Accessories
Several accessories are provided with each Naída CI Q90 Acoustic Earhook.
• Power Domes – an earpiece option provided in three sizes (S, M, L).
• Closed Domes – a less occlusive earpiece option provided in three size (S, M, L).
• Cerustop WaxGuard – required for minimizing damage to the xReceiver from wax buildup.
• Pin Removal Tool and Pin – required for attachment and removal of the Naída CI Q90 Acoustic Earhook.
The SlimTip earpiece is the recommended ear coupling for better retention and optimal sound delivery. The SlimTip is a custom earpiece
that must be ordered from Phonak and is not provided with the Naída CI Q90 Acoustic Earhook. If Phonak is unable to manufacture the
SlimTip due to the small size of the recipient’s ear canal then the Power or Closed dome options can be used.
Programming in SoundWave
The Naída CI Q90 EAS system is fit using SoundWave™ 3.0 software. You will find that fitting the Naída Q90 EAS system is very similar to
fitting the Naída CI sound processor with SoundWave with a few additional steps as described below.
Set-Up
Before Programming in SoundWave
Verify that the recipient has good residual hearing by performing unaided Pure Tone Audiometry across the frequency range:
a) Obtain Air Conduction Thresholds (AC)
b) Obtain Uncomfortable Loudness Levels (UCL) – optional; defaults will be used if not measured
For Existing Recipients - Upload programs from Naída CI sound processor
• Open SoundWave™ 3.0 software and connect the recipient’s Naída CI sound processor to the CPI-3.
• Recipient’s name will appear in the Action Pane. Select Open [Patient Name].
• Recipient’s current Naída CI programs will download and synchronise with SoundWave 3.0.
• Once the programs have been downloaded, disconnect the Naída CI sound processor.
For New Recipients - Create Patient File
• Choose the Patients Tab, then select New in the Action Pane.
• Enter all required information into the New Patient window, then select OK.
• The Implants window will open. Select New, enter the required information, then select Ye s for EAS, and click OK.
Note: The New Implant window will also appear when the headpiece is placed on the recipient.

Connect the Naída CI Q90 sound processor to SoundWave
• Connect the recipient’s Naída CI Q90 sound processor to the CPI-3.
• Prepare and initialise the processor, if necessary.
• Run an impedance measurement.
Enter Acoustic Parameters
• Select the Acoustic Parameters Tab and then select New Right or New Left.
Enter the Audiogram
In the Audiogram tab, enter the recipient’s unaided Pure Tone Audiometry Air Conduction (AC) Thresholds and Uncomfortable Loudness
Levels (UCL) across the frequency range.
Note: Values may be typed into the data grid or clicked and entered directly on the audiogram. If no response was noted for a specific frequency, select the
highest tested level, and then right-click on the value in the audiogram to select “Mark as No Response.” If a value is skipped, the data will be interpolated.
If UCL values are not entered, default values will be determined by the system based on the recipient’s AC threshold values.
Enter RECD values (optional)
• Select the RECD tab, and enter the recipient’s RECD values.
• If no values are entered, default adult RECD values will be applied.

Select Earpiece
• Under “Configuration”, select the appropriate Earpiece from the dropdown menu.
• Available options: Power Dome, Closed Dome, and SlimTip (with various vent sizes).
• The recommended SlimTip vent size is based on the entered audiogram and will be indicated with an asterisk (*).
• Save and Close the Acoustic Parameters.
Create a Program
Creating a Baseline Program
• Select Programs Tab.
• For recipients with existing programs, select their everyday program and open a copy of it.
• For new recipients, create a new program.
• Verify/set electric settings (e.g., Strategy, M-levels, T-levels, ClearVoice™, etc.) as per usual.
• Verify/set general settings (e.g., Audio Mixing, Mic Mode).
• For the everyday EAS program, an Omnidirectional Microphone Mode and Mic Only Audio Mix is recommended.
Note: Mic Source will default to “Processor Mic” and this is not editable in SoundWave.
• Turn on Live Speech stimulation and verify that the baseline program is at a comfortable level, making changes as needed.
• Turn off Live Speech stimulation.
Enable EAS in Program
• Under “Acoustic Settings,” enable the EAS Program by selecting On.
