There are a variety of accessories available to assist you with better hearing outcomes in different situations.
There are a variety of accessories available that can assist with your hearing performance when using the Cochlear Hybrid™ System.
The following accessories, or wired assistive listening devices, can be connected to your processor.
Personal audio cable
The personal audio cable can be connected to personal music systems, handheld games or other battery powered equipment to your processor.
The TV/Hi-Fi cable can be used to connect a TV, Hi-Fi or stereo, personal computer or other mains powered sound source to your processor.
*Note: You should use the mains isolation cable when also connecting to sound sources that use mains power)
Monitor earphones can be used by another person (with unaided hearing) to listen to the sound signal from the:
- in-built telecoil
- microphone and in-built telecoil together
- lapel microphone
- or an accessory (other than the lapel microphone) and microphone together
The lapel microphone can be used to improve communication in noisy environments. When using a lapel microphone, you will only hear sounds through the lapel microphone. Adjusting either the microphone sensitivity or volume changes the level of sound heard through the microphone.
The FM cable can assist in sending sound signals from a commercially available FM listening system to your processor.
In addition, commercially available wireless technology assistive listening devices you may want to try include:
Induction loop systems
The built in telecoil operates with induction loop systems
FM systems (such as the MicroLink Freedom)
The MicroLink Freedom® is a Phonak product that fits the Freedom BTE controller only. It will not fit into the Freedom mini BTE * controller.
The microphone protector should be in place at all times. Clean daily with a soft brush or cloth, while they are positioned on your processor. Replace the microphone protector when sound quality is degraded or it becomes dirty. If you are unsure they need to be replaced, try using new protectors and if the sound quality improves or is louder, dispose of the old protectors. Replace the protector every month (at the very least) to ensure optimal sound quality and hearing performance.
The Mic lock is a retention device used to hold your processor in place behind the ear. The Mic lock cannot be used while the Acoustic Component is connected to your processor.
The band version Mic lock can be used on the Freedom BTE (behind the ear) Controller, the Mini BTE Controller and the Bodyworn cable. The stirrup version Mic lock is for use with the Freedom Bodyworn cable only.
The standard ear hook enables the processor to be worn without the earpiece and cable.
The HybridTM acoustic component is a detachable part of the Freedom Hybrid sound processor. It is made up of an earhook, earpiece and cable. When connected to the sound processor, it is used to provide acoustic amplification of low frequency sounds that can be heard using the residual hearing in the recipient’s implanted ear. The Freedom Hybrid sound processor and acoustic component together amplify low frequency sound and send the acoustic output to the earpiece of the acoustic component, via the earhook and connecting cable.
The acoustic component plugs into the Freedom 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.
The earpiece sends low frequency sound directly into the ear. The acoustic component utilises eight fixed high-resolution filters, which operate between 125 Hz and 1800 Hz. Access to the entire sound spectrum is achieved by the combination of acoustic amplification and electrical stimulation. The active amplification range can be adjusted during programming. This means you can access low pitched sounds through the acoustic component and high pitched sounds through the Cochlear Implant sound processor. 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 clinic or hearing health professional will need to determine the necessary length of the acoustic component cable of the recipient. The cable length is pre-adjusted to the length determined by the clinic. The cable length can be further finely adjusted by +/– 3 mm. An over-travel marker (red dot – see Figure) indicates that the earpiece cable has been pulled out to the maximum length of extension.
