The Challenges

• People with a hearing loss face challenges in noisy environments such as classrooms The work place and the home environment

• Extensive studies have shown that hearing instruments alone are often not enough and that intelligent solutions are called for

• This typically meant using FM

Phonak Moving Forward

4

• Advances in technology brings opportunities to develop new ways of working with the hearing impaired world

• Phonak have always pushed the boundaries of technology and Roger takes us all forward to meet these needs Worldwide for now and the future

• The new global standard has arrived

What is Roger? 5

Roger is the new simple to use adaptive digital standard which provides unrivalled SNR in noise

and over distance.

Why Roger? 6

Definition of ROGER —used especially in radio and signaling to indicate that a message has been received and understood

• Received Order Given, Expect Results

What did it stand for? 7

•  Anyone who struggles to hear in poor acoustic environments •  This is anyone with a hearing loss regardless of aids, implants BAHA

Where should it be used. •  Pre school •  Education •  At home •  At work •  Socialising

Who is Roger for 8

How many of these are used outside the school classroom?

•  Roger is a new digital wireless technology standard •  Allows for low delay and reliable long-range broadcast towards miniature, low-power

receivers •  Operates on 2.4 GHz band (ISM), with intelligent adaptive protocols •  Audio bandwidth up to 7300 Hz •  Privacy is guaranteed

What is Roger?

9

•  Audio signals are sampled, digitized and packaged in very short (160 μs) digital bursts of codes (packets) and broadcast several times, each at different channels between 2.4000 and 2.4835 GHz

•  The 2.4 GHz ISM (Industry, Science and Medical) band is globally license free •  Frequency hopping between channels, in combination with repeated broadcast, avoids

interference issues •  The frequency hopping is adaptive, both receivers and transmitters are sniffing

continuously to find free channels and to avoid occupied channels •  End-to-end audio delay is well below 25 ms, and Roger systems are secure

Radio aids – What to look for?

1.  Overview 2.  Hearing Aid Checks 3.  Transmitter Checks 4.  Receiver Checks 5.  Audio Shoe Checks

1. Overview

•  Maintenance:- Roger combined with the latest paediatric aids will give your child every opportunity to make full advantage of every educational opportunity. However like all electronic devices they need to maintained on a regular basis to ensure that they are operating at their full potential.

•  Aid Functionality: It is also important to ensure that the hearing aid is also functioning optimally as The Roger System cannot function if the hearing instrument is not working optimally.

•  Basic Checks: Modern hearing aids and Roger are highly sophisticated, however there are still basic checks that can be performed, without the need for specialist equipment or knowledge. Enclosed are basic routines that can be performed on a regular basis to ensure that all the equipment is operating as it should be.

•  Preparation: The first check is to ensure that the aid or implant is set to The Roger or FM program. This may seem unnecessary but it is a common fault.

2. Hearing aid Checks Batteries

•  If you have any suspected issue the first option is to change the battery.

•  The battery has to work hard to power Roger and the hearing aid and this will cure most issues.

•  A battery tester is not a reliable checking device as the battery will not

be used in a real life scenario, powering the aid and the receiver. It could be that it is good in the tester but may not work in the aid.

•  It may also be that the aid will work but there is not sufficient power to

drive the receiver. This is common and can lead to confusion with suspicion, mistakenly falling on the Roger or FM system.

Hearing aid checks Moulds

•  If the mould is damaged battery consumption may be excessive as the aid fights to control feedback.

•  Visually inspect the ear mould and tubing for blockages or any signs of hardness or damage.

•  Cup your hand over the hearing aid whilst still in the child's ear. If you

hear a whistle then the mould should be investigated further.

Hearing Aid microphone checks

•  Front line care service and maintenance of the aids

•  Many modern aids have covers to protect the microphones and to reduce wind noise.

•  These can become blocked and may reduce the function of the aid. There are no rules as to when they need to be changed. This may be In different intervals depending on the child's life style. However a visual inspection is simple and should be implemented at least once per week. They should be clean and a light grey colour as shown.

» Damaged poor condition

Hearing aid contacts: Cleanliness & Corrosion

•  The commonest cause of intermittency of any device is corrosion or damaged contacts on the aid. This can cause intermittent FM / Roger signal or excessive battery consumption or general poor signal.

•  This is often mistaken for damaged audio shoes or malfunctioning radio aids so it is strongly advisable to make this a priority.

•  They should be cleaned at least once per week with a soft alcohol swab, to prevent corrosion build up. You should avoid any sharp or hard tools as, this may damage them.

•  Once these contacts are damaged the aid will need to be replaced.

3. Transmitter Checks

•  inspiro checks itself on start up so, will usually identify if there is an issue.

•  The best way to test transmitter is at distance. If you cannot get a colleague to help, plug an audio source into the transmitter and check the signal quality with a checker or via an aid and receiver you know works.

•  The battery should last about 12 hours – check charging routines. •  The microphone can only be tested via replacement with a spare,

speech or via a test box.

Advanced Transmitter Testing

•  If you are using a test box please ensure you use verification mode and the environment is as quiet as possible. Modern aids and Roger are very sensitive and it is easy to correct for apparent set up issues that have been mistakenly caused by noise in the environment.

•  Please also note that for test box verification microphone position is highly sensitive. Don't correct for this with out ensuring consistency first

4. Receiver Checks

•  Receivers are also susceptible to corrosion in extreme conditions and over long time periods so a visual inspection and monthly cleaning with a soft alcohol wipe is recommended.

•  Check With Roger inspiro or Monitor with FM inspiro is also a useful function to detect receiver damage.

» Damaged poor condition

Implants

•  Implants can also suffer form the same issue such as dirty contacts.

•  It is important o ensure that all electrical contacts are clean and free from damage.

•  This also includes connections to the batteries and the receivers.

5. Audio Shoe Checks

Ensure clean and free form damage

•  Audio shoes after contacts are probably the biggest source of problems.

•  They are constantly being removed and can become damaged.

•  It is difficult to predict how long they will last. It really depends upon how well they are looked after.

•  The only real maintenance that can be done is occasional cleaning of the contacts.

•  If you suspect they are faulty exchange for a new set.

•  Please ensure you destroy any suspect shoes as they have a habit of returning causing further issues

Audio Shoes Physical & Mechanical Checks

•  Please also monitor the mechanical fit of the shoe.

•  Check for loose fitting or damage.

Hearing Aid related issues •  Remember also the aid case wears over time.

•  You will notice this if you are having to replace shoes over a short period.

•  The only solution to this is to replace the aid.

Very isolated cases

Radio Aid • Check battery condition • Check shoes • Monitor/Check •  Frequency matched/Connected • Muted • Check Microphone condition •  Swop Receivers •  Swop shoes •  Listening check. Primary function • Use TEST KIT or another child as

tester or use their aids

Phonak aids in Test Boxes

1. Obtain the baseline printout as soon as you can 2. Important to compare like for like

What Test Box are you using? What software does your test box have? What stimulus are you using?

Verification with Test Boxes

July 2014 Roger Focus 35

Hearing Aids 1. Aid is on the correct Roger/FM program 2. Verification mode on transmitters. – to put in non adaptive Omni directional mode 3. 65dB transparency - compare curves 4. 80dB optional. Care must be taken as due to WDRC 10dB advantage is not always achievable. 5. Distortion. Is not measurable on a modern digital aid so should be listened for

Implants 1. Due too the nature of implants verification is not recommended by implant manufactures and ourselves. 2. The radio aid system should be checked in isolation prior further testing 3. However functionality of the receiver can be checked by using by the listening ear phones

Checking in order of priority

Typical questions are:- How long do you think a shoe will last? Can we mix technology? FM and Roger How do I connect to Audio Media? Can we connect to Hall PA systems? Do I need to Synchronise or Connect every day? What is Team teaching? What frequencies are the best? How do I connect to Soundfield? Do they work with all Cochlear Implants? What adapters are required? What shoes go with what aid? Why is Direct Input different from Loop systems ? Can we get coloured shoes? Etc

Q&A’s 37

We try to make it as simple as we can
