Why FM for Cochlear Implants 


FM systems are able to improve the signal-to-noise ratio and thus the user's ability to understand speech in noise. Three major 
factors that influence the signal-to-noise ratio and the quality of the speech signal are: background noise, reverberation, 

and distance. By delivering the signal of interest via FM (radio waves), the strength and quality of the sound remains constant 
across the distance from the speaker to the hearing impaired individual. FM systems consist of a transmitter with the 
microphone and a receiver, which picks up the signal via radio waves directly from the transmitter. 


Individuals with Cochlear Implants experience the same difficulty as hearing aid users in challenging listening environments. 
These situations usually involve distance from a main sound source (someone with a soft voice), unfavorable positioning in a 
room with background noise, or listening to a TV, radio or computer. It is well documented that improving the signal-to-noise 
ratio (SNR) for cochlear implant recipients through the use of an FM system improves speech recognition significantly in 

the presence of background noise. 


The MicroLink FM System dramatically improves performance in noise by providing a much higher SNR (by 
transmitting the speaker's voice via FM directly to the listener). On top of that multi-microphone technology, high resolution 
noise cancellation and Smart Noise Blocker technology improve intelligibility and comfort even further.

Transmitters for Cochlear Implants 


The choice of transmitter is most commonly based on where the implant user is primarily using the FM system. 





SmartLink is the first communi- 
cation device to incorporate 
multiple solutions into one 
instrument. It offers three micro- 
phone settings and bluetooth 
link for hands-free cell phone 
use. It provides the most versatile 
and high tech access to commu- 
nication.

TeamTeaching, where two teachers 
address a classroom at the same 
time. The second teacher also wears 
a transmitter, e.g. ZoomLink or 
Campus SX. This is also popular 
option in classrooms where the 


students with Cls would benefit 
from a pass around microphone. 


MicroLink Receivers for Cochlear Implants 


The miniaturized MicroLink receivers are available in different configurations depending on the speech processor. 
All multi-frequency MicroLink receivers include a digital frequency synthesizer and allow Direct Frequency Synchronization 
(DFS) with the Phonak transmitters and Automatic Frequency Synchronization (AFS) with the WallPilot. 





The MicroLink CI S has a plug-in connection 
for the MicroMLxS receiver. This allows 

for universal FM use with all compatible 
speech processors.

The 3G MicroLink adapter with MicroMLxS 
provides an earlevel FM. The MicroMLxS 
receiver attaches directly to the adapter on 
the Cochlear ESPrit 3G BTE processor giving 
freedom from cables.

Frequency Flexibility 


The key Phonak FM systems use digital frequency synthesizers. The various MicroLink receivers are frequency flexible. 

This allows the user to change frequencies or channels, as easily and often as needed. With this break-through multi- 
frequency technology, Phonak successfully meets the demands for flexibility and practicality made by today's world. One 
convenient way to use the system is to set the frequency of the Campus SX and then use that transmitter, with the push of 
a button, to set the receiver to the same frequency. SmartLink, ZoomLink and EasyLink automatically synchronize at start-up 
nearby receivers to matching channels. 

Not only are these products synthesized, but they are also programmable. This provides convenience to both the user and 
the audiologist. The default frequency of each receiver can be changed as needed. The transmitters can be programmed to 
have up to 40 different frequencies available, if needed. For the user friendly FM Successware programming software and 
training, please contact your Phonak FM representative. 





MicroLink Frequencies 

MicroLink systems include state-of-the-art narrowband FM frequencies, designed for the specific needs of the cochlear 
implant user. They operate in the 169-176 MHz (H-Band) and 216 MHz (N-Band) range. All the multi-frequency transmit- 
ters and receivers can be programmed easily and quickly with the FM Successware. Use only frequencies which are legally 
allowed in your country.

MicroLink Cl S Gain Control 


The MicroLink CI S interface has a screw-set or wheel gain control. It is recommended that the gain is set to the minimum 
position for the initial system hookup. Gain can be increased by rotating the control in the clockwise direction. Once the 
receiver is plugged into the speech processor, some adjustment of the CI Interface MicroLink CI S gain and/or the cochlear 
implant speech processor may be required. Speech testing in quiet using the FM transmitter only should yield similar results as 
the same test presented through the Cl headpiece microphone. If results are poorer through the FM systems, it may be neces- 
sary to increase FM level with the gain control on the side of the MicroLink CI S interface. Retest until the input level of the 
FM signal is optimized for speech discrimination. If this level is exceeded the patient may begin to experience some distortion 
and performance will deteriorate. 


For children, the screw-set may be preferred, so that gain can be set without concern that the control will be changed 
inadvertently. Adults may prefer to have the volume control wheel for adjustment in different environments.

Audio Mixing 


Audio mixing is the ability to keep the CI microphone active when the FM system is being used. On some of the earlier models 
speech processors, the cochlear implant microphone is deactivated when the direct audio-input is utilized. This prohibits users 
from hearing others in the room as well as their own voice when listening to FM. The processors that do not have built-in 
audiomixing capability include early model Spectra and S-series devices. Neurelec offers the audiologist the possibility to set, 
for each type of processor, different configurations of audio mixing between the headpiece microphone and the FM system. 
Ratio ranges from O to 100% (microphone/FM). For each configuration it is possible to set a gain function for both inputs as 
required by the patient. It is also possible to turn off the microphone to concentrate on the sound from the FM system only, 
although a 30/70 ratio would be more commonly used: the patient will get the benefit from the FM system but remains con- 
nected to environmental sounds. 


MicroLink Channel 


Each multifrequency MicroLink receiver comes with a preprogrammed default channel. Every time the system is turned on, it 
will come on to this default. If there is a need to temporarily change that channel, this can be done by “synchronizing” the 
receiver with the transmitter or WallPilot to a different channel. This change is only temporary, as the receiver will come back 
on to the default channel when it has been turned off. The default channel can be reprogrammed internally if necessary with 
the Phonak FM Successware. 


MicroLink FM Advantage 


The MicroLink receivers come with an internal gain setting of 10dB. With most hearing instruments, this provides an optimal 
loudness, or "FM Advantage" for the FM signal over environmental inputs. In some cases with hearing instruments and 
cochlear implants, this internal gain needs to be adjusted. Gain changes can be made with the FM Successware. 


Patch Cables 


In order to achieve predicted performance with your MicroLink Cl and cochlear implant, the correct patch cable must be 
used to connect the devices. Please refer to the following list to confirm that you are utilizing the correct cable.

Fitting 


For each processor, the fitting will consist of 2 basic steps. First, the loudness of the FM system compared to the environmen- 
tal input must be optimized. With the MicroLink CI S, this can be done with the external gain control. With the MicroMLxS, 
this must be done with the internal gain level of the device. A range of -6 to +24dB is available with +10dB as the default FM 
advantage. The experienced FM advantage may be different than +10dB, depending on microphone sensitivity settings in the 
speech processor. The second step is confirming FM benefit in noise. Adjustments in the relationship between the FM input and 
Cl headpiece microphone (or environment) may be made to improve performance with the FM System compared to the Cl 
alone. The adjustment is accomplished differently depending on the implant. 


Processor Sensitivity (Cochlear) 


The sensitivity control on the Nucleus devices with audio mixing is a crucial variable in FM benefit. This includes most 22 
Nucleus sound processors and all sound processors for Nucleus 24 sound processors. This sensitivity adjustment controls the 
input from the headpiece microphone, ultimately varying the audio mixing ratio between the cochlear implant microphone and 
the Wireless FM system. This control allows the users to adjust the FM advantage to match the conditions. Adults are very 
comfortable adjusting their FM advantage based on current conditions. For children, one sensitivity level should be employed 
in typical FM/classroom use. In order to optimize the setting, test the patient's speech understanding in noise (i.e. g. at +5 dB 
SNR). If the user's performance is not improved compared to using cochlear implant alone, the ratio between the FM input and 
the headpiece microphone may need to be adjusted. In general, reducing processor sensitivity will result in a greater FM 
advantage as a result of reduced input through the cochlear implant microphone. Adults will often tolerate a very low sensitiv- 
ity with the FM signal in order to focus on the primary signal. Children often prefer higher sensitivity with the FM signal in 
order to continue monitoring their environment and their own voice. 


If processor sensitivity is not adjustable and a volume map is fit with the FM system, FM advantage is set at one point (con- 
trolled by the fixed sensitivity point in the map). The benefit can be evaluated in the same method described above. The 
Nucleus Freedom sound processor employs a software selected audio mixing ratio, which can be adjusted to control the 
amount of headpiece microphone attenuation when the FM signal is being used. 


Audio Mixing (Advanced Bionics) 


Advanced Bionics uses fixed audio mixing functions in the map to control the ratio of headpiece microphone compared to the 
FM input. In theory both signals are being received at full strength. In practice, however, a slight reduction of -3dB is applied 
to both signal pathways in order to avoid loudness summation. Given that the input level may be higher from the audio-appli- 
ance (e.g. from the microphone placement of a transmitter at 5- 15cm inches from the teacher's voice) the signal-to-noise 
advantage should be maintained. Sound input to the HI microphone should not be perceptibly different with the auxiliary 
audio device connected or disconnected. In some cases a 30/70 mixing function will be needed to achieve FM benefit. In a 
map with this ratio, less gain than normal will be applied to headpiece inputs but the listener will remain in touch with the 
environment. Normal gain is still applied to the FM in 30/70. Note that when the FM is not in use, the listener should return to 
a 50/50 map to return input levels to normal. 


Sensitivity (MED-EL) 


The sensitivity control on the Tempo processor will not affect the audiomixing ratio. When the FM is in use, the patient will 
experience equal levels of headpiece microphone and FM input (with a slight reduction to account for loudness summation). 
If the sensitivity control is turned to off (turned counter-clockwise past 11:00 position until click is felt), the headpiece 
microphone will be turned off, resulting in the FM only condition.

. Insert three 675 batteries designed for use with cochlear 


implants into the MicroLink Freedom battery rack. 


. Plug the MicroLink Freedom into the controller. 


Press the round power button to power up the speech 
processor. 


. Use a program that is set to normal signal processing (rather 


than beam, auto sensitivity or ADRO) 


. The Freedom processor will automatically detect the presence 


of the MicroLink Freedom. The recipient will hear the environ- 
ment through the headpiece microphone and the FM com- 
bined. 


. Test the patient's speech recognition in quiet at normal sensi- 


tivity with the Cl alone and then through the FM system only 
(out of range of the headpiece microphone). Performance 
should be similar between these two conditions. It is not rec- 
ommended to change the FM level of MicroLink Freedom with 
he FM Successware. 


. Repeat speech recognition testing in noise. Performance with 


he FM should be significantly improved over the implant 
only condition. Cochlear recommends using a sensitivity level 
of around 12 for normal use. If FM benefit is not documented 
in the noise test, it may be necessary to reduce the sensitivity 
by pressing the left side of the es button. The sensitivity 
evel will be displayed in the LCD panel with the letter S.

9. A default mixing ratio of 3:1 is used with the Nucleus 
Freedom. This reduces the headpiece microphone by 9dB 
when the MicroLink Freedom is in use. This ratio can be 
adjusted in the implant audiologist's programming software. 
In some cases the 2:1 or 1:1 ratios may be preferred for more 
normal environmental audibility, or higher ratios up to 10:1 
for an "FM only" setting. The headpiece microphone reduction 
is maintained when the FM transmitter is switched off and 
MicroLink Freedom goes into squelch. 


10. When FM is not in use, press both sides of the 
increase/decrease button 7 to toggle back to M only. This 
will resume normal head piece microphone function. To re- 
engage the FM, toggle with the $i} button until "EA" flashes 
on the display and the M remains active. 


Freedom Listening Check: 


1. Attach the Cochlear monitoring phones to the receptacle in

Fitting 
1. Turn the 3G, transmitter and MicroMLxS FM receiver off. 


2. The switch on the bottom of the processor should be in the 
‘M' (microphone) position. 


3. Set the 3G adapter to the FM+M position and attach to the 
bottom of the 3G (may need to remove the clear plastic port 
cover on the bottom of the BTE). 


4. Set the MicroMLXS in the double green dot position and 
attach to the 3G MicroLink adapter. If the patient prefers the 
FM signal to be softer, the single green dot position may be 
used. 


5. Switch the processor into program 1 (P1 on the dial). 
It is preferred that the sensitivity control is enabled 
in P1. It may be necessary to visit the mapping 
audiologist for this change. With a sensitivity- 
enabled map, the user can alter the rotary dial up or 
down to increase or decrease the amount of signal 
from the Cl microphone, relative to the amount 
of signal from the FM system, as necessary. Cochlear 
recommends that the microphone sensitivity level of the 
Esprit 3G is set to 21-24dB when it is used with an 
FM system. Use the programming software to find the 
number on the dial that equates to this level. It will vary 
slightly between each speech processor. When this dial 
number is known, the 3G user should be counseled to use 
this setting with their FM system as it will result in an 
appropriate mix of FM and headpiece microphone. 
Anything below 1.5 on the dial will be FM only.

7. Determine speech recognition in quiet with the Cl alone at 
normal sensitivity. Repeat through the FM transmitter out of 
the Cl mic range. If scores with the FM signal are poorer, 
increase the gain of the MicroMLsS using FM programming 
software and a FM programming interface until comparable 
performance is achieved. 


8. Determine speech recognition with the FM system in noise. 
Decrease the mic sensitivity until significant FM benefit is 
demonstrated. 


9. It is recommended that the monitoring earphones are 
disabled in P1 to conserve power for the FM system. Failure to 
do this may result in intermittency for Cl or FM. They may still 
be used in P2. 


Troubleshooting - Perform a listening check 


1. There is a socket on the side of the adapter to plug in the 
monitoring earphones. When the earphones are plugged in 
and activated the map, they allow a hearing person to check 
the sound being received from the ESPrit 3G microphone and 
the FM system simultaneously. Typically P2 is designated for 
the monitoring phones. If you do not hear anything when 
using the monitoring earphones turn the processor off and 
on to P2 and try again. If still nothing, review the recipients 
map or contact your Cl audiologist. 


2. To check the FM system, remove the MicroMLxS and plug it 
into a working hearing aid and audioshoe or a Phonak 
MicroLink Headset checker. Turn on the transmitter and listen 
for a clear signal. 


Note 1: The earphone cable may pick up some interference and 
therefore may be noisier than the actual input to the 
recipient. 


Note 2: If the 3G adapter is lose on the 3G, please take precau- 


tions not to loose the attachment. The BTE mic lock will 
help to maintain the connection.

10. Most recipients wear their sensitivity control between 3.5 - 
4.5. When using the MicroLink System, optimum sensitivity is 
about 18dB. The Cochlear programming software will let 
you know what dial position corresponds to this level. This 
setting will produce a beneficial audiomixing ratio between 
the headpiece mic and the wireless signal.

. Use the processor in the N setting. 


. Determine speech perception in quiet with the Cl alone at 


normal (4-5) sensitivity. Repeat test with FM system. If scores 
are poorer with the FM signal, increase the gain of the 
MicroLink CI S until comparable performance is achieved. 


. Determine speech perception with the FM signal in noise. 
Decrease mic sensitivity in single-unit increments until 
significant FM benefit is demonstrated. Typically maximum 
benefit is achieved at 2-3.5.

these programmes to different sound environments following the 
procedure below: 


= 


. Switch off the speech processor, FM receiver and transmitter. 


2. Plug the MicroMLxS FM receiver directly into the auxiliary 
("AUX") input of the processor. 


3. Switch the processor on in the position defined for the use 
of the auxiliary system, and switch on the MicroLink receiver 
(prefererence the single green dot position). The processor 
automatically detects the presence of the receiver. 


4. Use the implant programming software to adapt these 
specific programmes (copy the programmes and authorise 
the auxiliary input). Adapt the appropriate audio mixing of 
FM and headpiece microphone. 


5. Determine speech perception in quiet with the Cl alone 
and then through the FM system. Performances should be
