Introduction

Purpose of this manual

This User Manual provides detailed step-by-step instructions on how to use, maintain and troubleshoot your Freedom™ Hybrid™ Sound Processor.

If you are new to your processor it is recommended that you read the Freedom Hybrid Quick Start Guide before reading this manual. The Quick Start Guide will provide you with the essential information you need to familiarise yourself with the basic operations of your processor.

Once you understand the basic functions of your processor, this manual provides more in-depth information that’s outside the scope of the Quick Start Guide – particularly in the areas of advanced user operations, maintenance and troubleshooting.

This manual provides the most comprehensive source of information available for your processor.

Overview

Your processor enables the combination of electrical and acoustic hearing in a single Behind The Ear (BTE) processor.

The processor is suitable for recipients who have residual levels of low frequency hearing. It is used together with a Nucleus

Hybrid Implant, Nucleus Freedom Implant or a Nucleus 24 Implant, (speciﬁ cally the CI24R and CI24M models) to transmit sound to the cochlea.

Your processor consists of the Processing Unit, coil, Freedom Hybrid Acoustic Component and a choice of three wearing options.

The BTE Controller allows your processor to be worn behind the ear as a BTE Processor. It is powered by three 675 disposable batteries or the BTE rechargeable battery.

The Mini BTE Controller also allows your processor to be worn behind the ear as a BTE Processor. It is powered by two 675 disposable batteries.

The Bodyworn Controller is worn on the body. It uses either two AAA nickel/metal-hydride (NiMH) batteries, or disposable alkaline batteries.

The three wearing options can be used interchangeably with the same Processing Unit.

Overview of your processor components

This section of the manual describes the component parts of your processor.

How your processor works

Sound can be received in four ways by your processor from:

The microphone• The in-built telecoil• An accessory• A mix of microphone sound and sound from the in-built telecoil •

or an accessory

Sound is then processed in the following way to produce hearing:

The sound is coded by the Processing Unit and transmitted 1. through the coil to the cochlear implant.

The low-frequency sound is transmitted through the Acoustic 2. Component directly into the ear through the earpiece.

The implant’s electrodes stimulate the cochlea’s hearing nerve 3. ﬁ bres, which relay the signals to the brain to produce hearing sensations.

Your processor has been programmed for use with your implant only. It is important to only use your own processor, to never swap yours with another person, and if you have two implants, to correctly match your processor to the correct implant.

Processor with BTE or Mini BTE Controller

Both the BTE and Mini BTE Controllers are normally attached to the Processing Unit and worn behind the ear. The Mini BTE offers a smaller two Zinc Air battery option than the standard BTE, providing a smaller and lighter wearing option.

Processor with Bodyworn Controller

The Bodyworn Controller is worn separately to the Processing Unit and attached with the Bodyworn Cable. The large screen makes it easy to view and change settings for adult users. The Bodyworn Controller is easily interchangeable with the BTE and Mini BTE Controllers.

The Processing Unit

The Processing Unit, incorporating Nucleus SmartSound™ technology, is the brain of your processor, where sound signals are encoded for transmission to the implant.

The Processing Unit is worn on the ear, with either the BTE Controller (or Mini BTE Controller) or the shoe that connects it to the Bodyworn Controller.

Both the coil (attached to the cable) and Bodyworn Cable are available in a variety of lengths and colours.

The controller

In addition to housing the batteries, controllers have:

A display that indicates the operations occurring.• Buttons that operate your processor.•

The BTE Controller contains three 675 disposable batteries or the BTE rechargeable battery. The Mini BTE Controller contains two 675 disposable batteries. The BTE and Mini BTE Controllers attach directly to the Processing Unit when worn.

The Bodyworn Controller can be worn in a pouch on a harness or attached to a belt. It can also be held in a pocket or secured to your clothing.

Freedom™ Hybrid™ Acoustic Component

The Acoustic Component works in a similar way to a standard hearing aid. The Processing Unit ampliﬁ es low frequency sound and sends it to the earpiece through the earhook and connecting cable. The earpiece sends low frequency sound directly into your ear canal.

Acoustic Component: with earhook (1), cable (2) and earpiece (3)



Avoid placing the Acoustic Component Earpiece against the magnet of the coil or against any other magnets, due to a low risk of damaging the receiver in the earpiece.

Wearing your processor

System diagrams of the different wearing options can be found in Overview of your processor components. They provide a good reference on how to assemble your processor.

Positioning your processor and coil

Your processor is contoured to ﬁ t neatly and comfortably behind the ear. A magnet holds the coil in place over the implant.

You may ﬁ nd it easier to turn your processor on before placing it on your ear. To turn on your processor push and hold the Select button for a few seconds, until you either hear sounds (if your processor is in place on your head), or the active program (P1, P2, P3 or P4) shows on the display.

Placing your processor on your ear/head

To place your processor on your ear/head:

Place the earhook over your ear while simultaneously holding 1. the coil in either of your hands. Do not let the coil hang freely as the strain can damage the cable.

Place the coil on your head; the magnet should hold it in place 2. over your implant.

Place the Acoustic Component Earpiece in your ear.3.

For a more secure or comfortable ﬁ t you can:

Use a standard Hybrid earhook if you no longer use the • Acoustic Component

Adjust the coil length and magnet depth/strength• Change the coil• Use a Mic Lock•

™

with the standard earhook

Adjust the length of the Acoustic Component Cable (this should • be performed by your clinician only)

Read the following sections for more details.

182630 Hybrid SP User Guide ISS2 D02 RJD.indd 11182630 Hybrid SP User Guide ISS2 D02 RJD.indd 11 3/08/2009 12:42:32 PM3/08/2009 12:42:32 PM

Removing your processor from your ear/head

To remove your processor from your ear/head:

Grip the earpiece with one hand and loosen it. Take care not to 1. hold the earpiece by its cable.

Continue to remove the earpiece with one hand, while removing 2. the Processing Unit and coil with your other hand. Take care not to hold the Acoustic Component Cable or coil cable.

Changing the Acoustic Component

The Acoustic Component plugs into the Processing Unit at the earhook connector. If you no longer wish to use the Acoustic Component, you can replace it with a standard earhook that does not include an earpiece.

It is not possible to remove the earpiece from the cable and earhook. The earpiece is part of the Acoustic Component, which cannot be disassembled. The Acoustic Component can only be separated from the Processing Unit at the earhook.

The shape of the Acoustic Component Earhook cannot be adjusted but it provides an excellent ﬁ t due to the presence of the earpiece and connecting cable.

Two different earhooks are available:

The earhook that comes as part of the Acoustic Component • An alternative standard earhook that enables your processor to •

be worn without the earpiece and cable

To remove the Acoustic Component or standard earhook, twist the earhook 90 degrees as shown and pull it away from the Processing Unit, taking care not to pull the cable.

To attach the Acoustic Component or earhook to the Processing Unit, simply push the plug on the Processing Unit into the socket of the earhook.



To avoid damaging the cable, grip the Acoustic Component by the earhook when pushing it in, or pulling it out. Do not hold it by the cable.

Adjusting the coil and magnet

Make sure the coil is positioned correctly against the implant by placing it where the magnet “pull” feels the strongest.

You can change how close the magnet sits to your head by changing its depth in the coil, effectively changing its “strength”. You can also replace the magnet with a stronger or weaker one if changing the depth of the magnet in the coil is not sufﬁ cient.

Changing magnet depth

To adjust how tight the coil sits against your skin, try adjusting how closely positioned the magnet is to your head by changing its depth in the coil before changing the magnet itself.

Adjusting the magnet

To adjust the magnet position (depth in the coil):

Insert a thin coin or screwdriver into the magnet slot on the 1. topside of the coil.

Twist in a clockwise direction from above to increase magnet 2. strength, or twist in an anticlockwise direction from above to reduce magnet strength.

Do not force the magnet to turn if it becomes difﬁ cult to turn during insertion or removal. The movement should be smooth and turning should need only a small amount of force. If turning becomes difﬁ cult:

The magnet may not be correctly aligned in the coil.• You may be turning the magnet in the wrong direction.•

Changing magnet strength

To change the magnet to a stronger or weaker one:

Insert a coin or screwdriver into the magnet slot on the topside 1. of the coil.

Twist in a clockwise direction from above to remove the 2. magnet.

Insert the new magnet into the underside of the coil.3. Twist in a clockwise direction with your ﬁ ngers from below to 4.

further insert the magnet. If necessary, use a coin or screwdriver from above to further 5.

adjust.

If the magnet strength is too weak the coil may fall off. If it is too strong, it may cause discomfort or skin irritation.

Consult your clinician if you wish to change the magnet strength. Store spare magnets safely. Store them away from credit and other

cards that have a magnetic strip.

Changing the coil

Coils are available in various colours and lengths. If you wish to change coil colour or ﬁ nd that the cable is too long or too short, you can change the coil. The coil cannot be separated from the coil cable.

To remove the coil from the Processing Unit, always hold the plug securely with two ﬁ ngers and pull it away from your processor. You may damage the plug, cable or the Processing Unit if you pull the cable or twist the plug.

The coil plugs into the Processing Unit as shown below. Make sure the coil is securely attached to the Processing Unit by pushing the plug ﬁ rmly into the socket.

Changing the coil

Regularly check to see if there are any breaks in the coil cable, particularly if you are experiencing intermittent sound. If there are breaks you will need a new coil. If there are no visible breaks it is still a good idea to test the coil by using a new one.

If you plug the coil cable into the Processing Unit when your processor is turned on, your processor may turn off. If this occurs, hold down the Select button to turn your processor back on, that is, until you either hear sound or the display shows.

A secure ﬁ t using the Mic Lock™

When using the standard earhook instead of the Acoustic Component, a Mic Lock

™

can be used to hold the Processing Unit in place behind the ear. The Mic Lock cannot be used while the Acoustic Component is connected to your processor.

The tube Mic Lock can be used on the BTE Controller, the Mini BTE Controller and the Bodyworn Cable. The stirrup Mic Lock is for use with the Bodyworn Cable only.

To ﬁ t the Mic Lock:

For the tube Mic Lock, thread the earhook and Processing Unit 1. through the Mic Lock tube and move it down the unit until it ﬁ ts ﬁ r m l y .

For the BTE or Mini BTE Controller, position the Mic Lock between the buttons, so the transparent band covers the display. Alternatively, clip the stirrup Mic Lock into the two holes towards the base of the Bodyworn Controller shoe.

Put your processor on your ear. 2. Bring the tubing around to the front of your ear and up to the 3.

earhook. Either sized earhook can be worn with the Mic Lock.

If the tube Mic Lock does not feel comfortable, for a better ﬁ t, rotate the band around the base of your processor.

Hold your processor ﬁ rmly in place, and determine where the 4. tubing should be cut.

Mark the tubing, allowing for an additional few millimetres, so it 5. can attach to the earhook.

Cut the tubing only when you are certain the length will allow 6. a secure and comfortable ﬁ t. It is important not to cut it too short.

Feed it on to your earhook. 7.

Fitting the Mic Lock

To wear the Processing Unit with the Mic Lock in place, fold your ear down and gently pass your ear lobe through the loop made by the Processing Unit and Mic Lock until it is in position on your ear. Alternatively, bring the tubing to the front of your ear and feed it on to your earhook.

Your processor should ﬁ t securely with the Mic Lock in place. To remove the Processing Unit with the Mic Lock attached, fold

down your ear lobe and reverse the process. Alternatively, ease the tubing off the earhook.

The display generally shows the program in use, for example, P1 and whether the microphone, in-built telecoil or both are operating. The information on the display varies according to the program and functions being used.

When the lapel microphone is used with the BTE or Mini BTE Controller, no M or T shows on the display.

The Bodyworn Controller display (backlight) will light up for a few seconds when a button is pressed, or a help message ﬁ rst shows on the display.

In addition, help messages may show, either as a warning or sign that action needs to be taken. For example H2 shows for low batteries, or H3 if the coil is not in place or is not working. For more information on help messages, see Troubleshooting.

When the microphone sensitivity or volume is changed, the symbol, S or V will show on the display correspondingly. This lets you know which function you are changing. The sound level will show as a number, and change when you push the increase or decrease button.

The display will return to the normal P status when no further changes to the level occur.

Processor programs

Up to four sound processing programs (P1 to P4) are available for your use, providing that your clinician has enabled them for you.

You can change programs to help you hear better in different listening situations.

Program options available

The program levels and features are selected at the programming session, when your clinician programs your processor to suit your hearing needs.

By including different features, the programs can be varied to help you hear better in different listening situations:

Programs can include ways to improve your hearing, using • Nucleus SmartSound.

While you are normally able to vary settings for microphone • sensitivity or volume, your clinician can also have them set at a ﬁ xed level within a program so they cannot be changed.

If the private or public tone is not operating, you will not hear any tones when you press the Select button. However there will be a slight gap in sound while changing between the programs. To continue changing to another program, wait until you hear the sound from the new program before you press the button again. If you press the Select button when there is no sound, your processor will not move to the next program. You need to wait for the sound ﬁ rst before you press the Select button again.

Continue pushing the Select button brieﬂ y until you reach the program you want. Your processor will only move through the number of programs that your clinician has set up. For example, if you only have two programs set up, it will only move through P1 and P2 (P3 and P4 will not show).

The program you select operates until you press the Select button again. When you switch your processor off and on again, it will return to the program and settings you were using before you switched it off. That is, your processor will remember the last program you used, including any changes to the microphone sensitivity and volume settings you made.

Changing your perception of loudness

You can use the microphone sensitivity and volume controls to change the loudness levels of the sounds you hear.

Your clinician will set up your programs so you:

Can change both microphone sensitivity and volume.• Can change microphone sensitivity only.•

Cannot change microphone sensitivity and volume.• Each of your programs may be set up differently. Microphone sensitivity and volume settings are saved for each

Controlling microphone sensitivity

The microphone sensitivity controls the softest level of sound picked up by the microphone. The recommended level is 12. Your clinician, however, may have programmed the sensitivity control to change the sensitivity of the implant sound and volume of the earpiece simultaneously.

If sensitivity changes are enabled, you can:

Decrease the sensitivity of the implant sound to reduce • background noise in noisy situations.

Increase the sensitivity of the implant sound to hear very soft • sounds in quiet situations.

To change the microphone sensitivity:

BTE and Mini BTE

1. Brieﬂ y push either the Increase or Decrease button.

The display shows the current sensitivity level.

2. Continue pushing until you reach the sensitivity level you want.

Bodyworn

Change the volume of the implant sound alone.• Change the volume of the earpiece alone.• Change volume of the earpiece and sensitivity of the implant •

sound simultaneously.

If volume changes are enabled, you can:

Reduce the volume if sounds are uncomfortably loud.• Increase the volume if speech, including your own voice, is too •

soft. The volume level is shown as a number between 0 and 9. If you are adjusting the volume setting often, or if adjusting the

volume causes you discomfort, consult your clinician. To change the volume level:

BTE and Mini BTE

1. Push either the Increase or Decrease button and hold for more than one second.

Using SmartSound™ in different listening environments

Your processor incorporates innovative Nucleus SmartSound technology.

SmartSound is designed to mimic the ear’s adaptive capabilities, delivering improved hearing outcomes and behave in the same way as natural hearing, providing control over how sound is processed in different listening environments.

There are various SmartSound 2 options available, grouped within four hearing environments. The following functions may be included as options, within a program:

Everyday is ideal for the typical listening conditions of everyday • life and can automatically adjust the sounds you hear for maximum clarity and comfort.

Noise is suitable for environments with signiﬁ cant background • noise, improving the audibility of wanted sound from various positions.

Focus is useful where there is signiﬁ cant background noise but • focus is needed on a single source of sound.

Music is used to listen to all types of music from any audio • source.

Discuss with your clinician how you want these options applied to your programs. You can only use these options if your clinician has set them up in one or more of your four programs. You can then use a SmartSound 2 option by changing to the program(s) where it is available.

Using the Telephone with your processor

You may use your telephone and your processor with:

The normal microphone setting.• The telecoil, which is displayed as the T on the display.• The telecoil and microphone on at the same time (depending on •

how your clinician has set up your processor), which is displayed as MT on the display.

To use the telephone with your processor on the microphone setting:

Position the telephone handset by lining it up with your 1. cheekbone.

Move the handset up and backwards so that it is slightly above 2. the ear.

Turn the handset so that the earpiece touches your head. This 3. will help you hear the voice on the phone more clearly.

To use the telephone with the telecoil or telecoil and microphone setting:

Press the Increase and Decrease buttons for a few seconds until 1. your processor changes to the T or MT setting.

Position the handset slightly lower on the ear and further back 2. than the position suggested for the microphone setting.

Do not hold the handset too high or too far back behind the ear. In these positions the signal will not be optimal.

The optimal position will be different for different telephones. Try moving the phone earpiece around to achieve the best sound.

For information on the warning sounds or indicators, see Troubleshooting.

Remove batteries when they are ﬂ at, or when the battery holder is to be stored for a period of time.

Use only battery types recommended by your clinician or Cochlear Limited. Other types may not have sufﬁ cient energy to allow your processor to either function properly or last for a long time.

When using disposable batteries, never mix fully charged batteries with partially charged ones. Always change each battery. It only takes one low or ﬂ at battery to stop your processor from working. Similarly, never mix brands or battery types, for example, Zinc Air with alkaline batteries.



Flat batteries may leak corrosive ﬂ uids and cause damage if left inside your controller.

Dispose of used batteries in accordance with your local

regulations.

Never dispose of batteries in ﬁ re.

Do not let children replace batteries without adult supervision.

Make sure that batteries are kept out of reach of young

children.

All battery types

Carry spare batteries in a closed plastic bag for safety, making •

sure they do not come into contact with either each other or

metallic objects, for example coins or hair clips. Any of these

situations may accidentally short circuit the battery, which may

heat up and even crack open.

Only charge rechargeable batteries. Do not recharge disposable •

batteries, e.g. zinc/carbon or alkaline batteries.

Store batteries in cool places. •

Do not heat batteries, for example never leave batteries in •

sunlight, behind a window or in a car.

Never immerse batteries in water. •

Do not deform batteries. For example, do not force them into •

your processor. Do not drop batteries on hard ﬂ oors.

If a battery has leaked ﬂ uid, do not allow the ﬂ uid or liquid to •

come in contact with skin or eyes. If contact is made, wash with

a lot of water and seek medical attention. It is always a good

idea to wash your hands after you have handled batteries.

Rechargeable batteries

Ensure your battery charger is suitable for the type of battery •

you are using.

After storing rechargeable batteries for an extended period, •

it may be necessary to charge and discharge them (that is, use

them until they are fully ﬂ at) several times to obtain maximum

performance.

Remove rechargeable batteries from the charger, immediately •

after they are charged.

As you use rechargeable NiMH batteries, their battery life will •

shorten. When batteries no longer last for a reasonable period

of time, dispose of them carefully, in accordance with local

regulations.

Replacing the microphone protector

Replace the microphone protector when sound quality is degraded or it becomes dirty. If you are unsure if it needs to be replaced, try using a new protector and if the sound quality improves or is louder then dispose of the old protector. Replace the protector every month (at the very least) to ensure optimal sound quality and hearing performance.

You can also ask a hearing person to check for the presence of sound by using the monitor earphones. Refer to Monitor earphones for further information.

1. Pull out the coil by holding the plug ﬁ r m l y .

Do not pull the cable.

2. Remove the dirty protector using your ﬁ n g e r n a i l .

3. Attach the new protector.

Always use the microphone protector. It protects your processor from dirt and moisture.

Cleaning the Acoustic Component

Clean the Acoustic Component on a regular basis so as to remove the build up of wax and to optimise acoustic performance.

Two tools are supplied with your Acoustic Component; a brush and a vent cleaner. The brush is used daily to clean both the ear shell and the WaxBuster ﬁ lter if you have it (see Using your wax management system below). The vent cleaner is used to remove wax from the earpiece vent. Do not use the vent cleaner to clean any other part of the Acoustic Component or processor.

Clean the earpiece daily with a dry cloth. Clean away any traces of wax from around the vent opening. If necessary, clean the earpiece with a cloth slightly dampened with cleaning ﬂ uid that is suitable/ recommended for standard hearing aids. Always handle the Acoustic Component with care on a ﬂ at surface and take particular care not to drop it or to twist the earpiece cable. The wax ﬁ lter should be cleaned (WaxBuster system) or changed (NoWax system) when it is clogged with wax or when the earpiece does not sound normal.

Remove the Acoustic Component from the Processing Unit monthly and clean the connectors with a dry cloth. Do not use chemicals to clean the connectors.

Using your wax management system

The excretion of wax inside the earpiece can reduce hearing performance. Two wax management systems are available from Cochlear that help to prevent wax from entering the earpiece: NoWax and WaxBuster.

Your audiologist will help you to decide on the most suitable wax management system for your needs.

NoWax system

Depending on the amount of wax deposited, Cochlear recommend that you change the NoWax earpiece ﬁ lter every month. Change the ﬁ lter if you perceive a decrease in acoustic hearing performance or if you notice that the ﬁ lter is blocked.

To change the NoWax ﬁ lter:

1. Remove the tool (3) from the shell (1). One arm of the tool is a ﬁ lter removal tool (4) and the other holds a new ﬁ l t e r ( 2 ) .

2. Push the removal tool into the used wax ﬁ lter on the earpiece and remove the ﬁ lter.

3. Push the new ﬁ lter into the earpiece.

4. Dispose of the used removal tool and used ﬁ lter.

WaxBuster system

You do not need to change the WaxBuster ﬁ lter. Use the cleaning brush supplied by Cochlear on a daily basis to remove excess wax from the ﬁ lter. Clean the ﬁ lter with a dry cloth.

If you think that there might be a problem with your WaxBuster ﬁ lter, please contact your audiologist. Do not try to remove or replace it yourself.

Care

Your processor and Acoustic Component should work well, even when used in very cold or hot outdoor temperatures. Generally, in cold temperatures your body heat is sufﬁ cient to keep your processor warm and working well. In very cold weather, wear a hat or headband over your processor. When not worn, do not leave your processor in very hot areas, for example in sunlight, behind a window or in a car.

For information on the temperature ranges your processor is tested to perform within, see Technical information, Environmental conditions.

Do not wear your processor while bathing or swimming. If your processor does get wet, wipe it dry with a soft cloth and place it in the dry aid kit or Dry & Store

for at least 12 hours. If it subsequently does not work, return it to your clinician. Cochlear Limited cannot guarantee that they will be able to repair any water-damaged part.

Take off your processor when sleeping as you may put strain on the earpiece cable and damage it.

Take off your processor when applying powder, makeup or hair product. These substances can get into and damage your processor.

Avoid getting sand or dirt into any part of the system. If this happens, shake out as much as possible, and if necessary contact your clinician to arrange for its repair.

Storage

Store your processor overnight or when you are not using it, in a dry aid kit or drying pack such as the Dry & Store. Moisture or humidity may cause your processor to cut-out or stop working. Before using the dry aid kit, read the manufacturer’s instructions for use. It is recommended that you store your processor and Acoustic Component fully assembled.

Dry aid kit Dry & Store

By not wearing the processor and Acoustic Component overnight you will help your ear to dry and minimise the risk of putting strain on the earpiece cable while turning in your sleep.

To store your processor overnight, you may either leave your battery/batteries in the controller, or remove the battery holder from the controller and place it separately, with the batteries in the holder, in the drying kit.



Keep the drying chemical material away from young children. Swallowing this material can cause serious internal injuries.

For long-term storage, remove the batteries from the controller. Remember to store them separately, to avoid them from short circuiting each other.

You can also buy dry aid kits or drying packs for use with your processor, from an electronics store or pharmacy.

Disposal

Dispose of electrical components in accordance with your local regulations.

High-pitched tones are heard when:

Your processor completes a function.• The buttons are locked or unlocked.• You change programs. For example, when you move from P2 •

(program 2) to P3 (program 3), three tones are heard.

Low-pitched tones are heard when:

The battery/batteries are low (two low tones).• The batteries are ﬂ at (four low tones).•

A high-pitched tone followed by a low-pitched tone is heard when the wrong button is pressed.

If you have difﬁ culty hearing the private tone, ask your clinician to adjust it at your programming session.

Public tones

The public tone is only available with the Bodyworn Controller. Both you and people around you hear it. It allows people around you to assist you when there is an alarm, for example when the batteries are going ﬂ at.

Public tones can only be heard if your clinician activates them for a particular program.

Low-pitched tones are heard when:

Your processor completes a function.• The buttons are locked or unlocked.• You change programs. For example, when you move from P4 •

(program 4) to program P1 (program 1), one tone is heard.

High-pitched tones are heard when:

The battery/batteries are low (two high tones).• The batteries are ﬂ at (four high tones). • A H3 coil error or H4 audio error occurs. You will hear four •

high-pitched tones, which will repeat every minute until the problem has been ﬁ xed.

A high-pitched tone followed by a low-pitched tone is heard when the wrong button is pressed.

Hybrid Hybrid is the brand name of the electro-

acoustic hearing solution available from Cochlear Limited, that enables hearing by means of both electrical stimulation of the cochlea and acoustic ampliﬁ cation of sound into the ear canal.

Hybrid Acoustic Component

Part of the processor that channels low-frequency sound through the earpiece into the ear. The Hybrid Acoustic Component Consists of the Hybrid earhook, earpiece and connecting cable.

Implant An implanted electronic device that bypasses the

damaged hair cells in the inner ear or cochlea and stimulates the hearing nerves directly. It consists of a receiver stimulator and electrode array.

MAP A MAP (or program) can be described as the

settings that determine how a processor converts environmental sound into channel stimulation data for the recipient’s electrode array.

Mini BTE Controller

The Mini BTE Controller contains two 675 disposable batteries and is slightly smaller than the standard BTE Controller. It has a display that indicates the operations occurring and buttons that operate your processor.

Mic Lock A ﬁ xing aid used to hold your processor in place

behind the ear.

Nucleus Cochlear Limited was established as a division of

the Nucleus Group in 1981, and was the original startup company in Sydney. Nucleus is used as a brand name for much of the Cochlear product range.

Program See MAP.

Processing Unit Component of the processor where sound signals

are encoded for transmission to the implant.

Processor See Sound Processor.

SmartSound SmartSound is a suite of four input processing

technologies. These technologies can be applied to your available program slots, providing control over how sound is processed in different listening environments.

SmartSound 2 SmartSound 2 is an application of SmartSound

technology. It is designed to mimic the ear’s adaptive capabilities, delivering improved hearing outcomes and behave in the same way as natural hearing, providing control over how sound is processed in different listening environments.

Sound Processor

Captures and codes sound which is then transmitted through the coil to the cochlear implant. It consists of a Processing Unit, controller and coil.

Telecoil The in-built telecoil allows you to receive signals

from a hearing aid compatible telephone, a room ﬁ tted with an induction loop, or personal induction loop, such as a neck loop or cushion loop (commercially available).
