3Oticon Product RangePREMIUMREFERENCESTANDARDBASICThe point to stress here is that Oticon is now really a full range supplier and not just a supplier of high end solutions. We have developed new and dedicated solutions in each price category.Premium. DigiFocus IIReference. DigiLifeStandard: ErgoBasic: SwiftAll of these instruments are programmableAll can be programmed by EasyFit or OtisetAll offer the highest quality hearing care in their particular segment.The point is that from a Swift, one can expect a good sound quality with low distortion and background noise individually fitted according to an accepted fitting protocol. The other instruments offer tangible user benefits from this starting point. Ergo offers feedback management, programmable t-coil and greater fitting flexibility. The digital instruments offer fully automatic operation and better speech understanding in noise. Which instrument is the best depends on the lifestyle, needs and spending power of the hearing impaired person.- a full range of competitive programmable products

5Operations Concept Developed with focus on efficient operations Automated production with use of robotsReduced number of componentsIn order to develop lower priced quality hearing instruments, Oticon has developed a new manufacturing process. The efficiencies gained by this process are what enables us to offer high quality hearing care at lower prices.High quality components. The new Oticon lower priced units are made in Denmark with the highest quality transducers and amplifier units available. Cost savings have not be achieved through the use of cheap components.Reliable and well established technology. The use of microchip technology has enabled the use of a very reliable and robust solid print technology in the amplifier unit.Automated production requires precision and control over all aspects of the manufacturing process. Once established, there is very little spread in the quality of the finished product.Reduced components. By placing most of the instruments components on a new microchip, there has been a very big reduction in the number of components. This enables for reductions in manufacturing and servicing costs associated with the instrument.

This took its starting point in looking are reliability statistics over what things tend to cause the most problems in BTE instruments and improve them. These are :Switches. All switches on the BTE instrument are of a simple and robust design.Battery damage. The potassium hydroxide that leaks out of zink air batteries causes corrosion in switches and amplifiers. This problem has been addressed in the BTE instruments by use of the tin coated stainless steel battery contacts and the battery wall to hinder battery fluids from entering the instrument.The swivel hook prevents damage caused by over tightening. It provides a tight acoustic seal and the components have been exhaustively tested to ensure that the hook does not become loose even when turned thousands of timesThe capillary design of the join between the over and under shells conducts moisture along the capillary rather than allowing it into the instrument.Chip on board means that all but three components can be included in an integrated circuit (chip). The solid board gives a base upon which such fixtures as solder points to transducers and volume control can be attached or removed easily, with minimum chance for damage. If sweat enters the instrument from the VC hole, then it will not collect in folds, but will eventually evaporate. The amplifier is conform coated for extra moisture resistance.

10Ergo means ‘therefore’ in latin Ergo means ‘therefore’ in latin. When we have presented all of the good features in Ergo therefore we think dispensers should prescribe it. It is not because of ergonomics, although the instrument is very strong on this point as well. The word Ergo is presented with an explanation mark when used as a logo to emphasise the point. We recommend that Ergo is always presented prior to Swift if presenting the two instruments at the same time.
11Redefining the fundamentals in hearing care We have carefully chosen to never use the word ‘basic’ in any of the Ergo material. This is not just another standard instrument. The word “fundamentals ” is carefully chosen and it is important to emphasize that with Ergo the user will get more than previously possible in this segment. The fundamentals that we ‘redefine’ are we set new standards in terms ofReliabilityFeedback controlSound qualityEasy of useEase of fit and acceptanceRedefining the fundamentals in hearing care
12The Ergo Product Concept Cosmetically attractive & easy to handleEasy to fit, flexible programmingExcellent sound qualityFull range of stylesAll essential features and optionsNew solutions to fundamental challengesWhen developing the new BTE instruments we worked closely with the worlds largest dispenser of hearing aids, the National Health Service in the UK . They were adament that the single most important feature for delivering high volume hearing care is reliability. Therefore the whole development process started with aiming to develop the most reliable instrument in the market.Sound quality we define as low distortion and low internal noise. It is important to get the customers to listen to the instrument before the workshop is finished. All experiences show that they will be impressed. Users of the instrument experience the sound quality as being clear and undistorted.Easy to fit. The experience of Microsoft shows that clearly people do not like learning new software packages.The same goes for hearing instrument fitting software. Once people know one or two packages, they are reluctant to change. The fitting software in Ergo is straigtforward, but people will only believe this after they have used it. Every demonstration of Ergo or Swift must be accompanied by allowing the audience the chance to fit the instrument. This should be enough to get them started with fitting the instrument after the presentation.Ergo is a range of instruments where cosmetics have been placed in a high priority. New instruments these days must take cosmetics into account.The Ergo range will include such features as tamper resistant vc cover, battery drawer , CROS etc that are required in a complete instrument series

14The Ergo BTE Attractive Flexible Reliable Programmable Simple to fit to useto repairErgo is to be positioned in Dispensers minds as a high quality, versatile hearing instrument range which can be used in a wide variety of fitting situations and meet a wide variety of different client needs.It is positioned as an instrument range which provides a better hearing instrument than the current PerSonic and CommuniCare instruments. It is important to note that Ergo should be able to increase the market share of Oticon instruments in its price category. It is not simply the intention to go after current PerSonic or CommuniCare dispensers and get them to change to Ergo. We wish to get dispensers fitting instruments such as Swing and Logo to see the advantages of Ergo and switch to this product.

Also show that the battery can be “picked up directly from the palm.the use of a shoe for programming means that the dispensers will not need any new cables. They can use a standard Oticon #3 cable. which is also used for most other instruments. It is also Siemens compatible.GSM immunity is one of Ergo’s strongest features. It show the best test results we ever measured on any instrument (including DigiFocus). Some may say that old people do not use cellular phones - but they do sit next to others that do. With Ergo you can normally use a GSM phone on the same ear that you wear the instrument. This one features alone puts Ergo in a class of its own. The test results are just as good for Swift, but we emphasise them more with Ergo.

17Ergo BTE Fitting Range Re. NAL RP The fitting range range is calculated using NAL RP (Revised Power) - one of the World’s most known rationales for linear hearing aids.NAL RP is also the default rationale setting in OtiSet for Ergo and Swift. Other options are Pogo II and Corell.The icons show the type of hearing losses you can fit with Ergo - reverse sloping, flat, sloping and steeply sloping. Please emphasize that the gray icons represent hearing losses, where Ergo is not recommend - cookie bites, ski slopes and left corner audiogrammes - for these very difficult and special hearing losses we recommend DigiFocus II.Underline for the workshop that the audience should not try a difficult audiogram “to see if it fits”. Because the instrument is not designed for these.In other words - Ergo will fit 80 percent or more of all hearing losses in a normal clinic. Presbyacusis, conductive, mixed etc.Ergo BTE can replace PerSonic 400, 410, 420 and much of 440. With one instrument. That is why we call it flexible...Re. NAL RP

Patients used to the PC sound (with a lot of distortion). Most new patients will prefer the AGC slow, whish is very comfortable. No other instruments have the AGC slow (which is very slow - release time 1.2 second). Demonstrate the comfortable sound and the turn the AGC fast on and say - that is how other instruments sound.- The preset gain range is also very large. The large gain and MPO range make Ergo and extremely flexible instrument - is replaces PerSonic 410, 410, 420 and in many cases 440. In other words . the dispenser can use BTE instrument for a lot of different hearing losses -which is a clear benefit.Feedback management system is also one of Ergo’s unique selling points. The system is new and we have filed a patent application for it. It is nothing like any older systems. Make sure to include the three slides with Feedback Management in any presentation and makes sure to know how to sell the system and how to demonstrate it in the workshop.The programmable telecoil is also an Ergo specialty. Most other instruments in this class will have such a feature and it is well suited to position Ergo as a “top-up” instrument.

24Ergo Programming with EasyFit or OtiSet BTE:Programming cord and shoeITE:Programming cord and FlexConnect
25Programming with OtiSet ‘Agram slope’ is a combined Low Frequency and High Frequency cut filter control. It is a new word and needs to be explained. In other Oticon systems ‘A-gram’ refers to a low frequency cut function The word ‘slope’ is included in the title to underline the fact that the controller is for with high frequency and low frequency control and is therefore used to shape the overall frequency response to fit the overall audiogram shape.The gain is the preset gain control.The section on feedback manager should be presented first from a theoretical perspective ( following slides) and then given a practical demonstration.To demonstrate the feedback management control in a workshop connect the instrument to OtiSet. Turn the volume up until the instrument starts to whistle (i.e. 3.4). Then turn the feedback management control down until it stops to whistle (3.2 in this case). Then turn the volume up and demonstrate that now the instrument will no longer whistle - even with the volume at 4.0.The most effective demonstration of the AGC system is for dispensers to listen to it. This should take place during the fitting workshop.
26Programmable T’coilFrom the this screen the following changes can be made to the t-coil setting:1. Any combination of M or T. The T can also be disabled.2. The level of the t-coil beep. The number in this field indicates that equivalent input level of the t-coil beep. Ie if this number is 70 the the output level of the beep will be 70dB + the gain of the instrument.3. This control activates or deactivates the 6dB t-coil boost relative to the microphone setting.
27Ergo Feedback Management Feedback elimination at the click of a mouseEssential high frequency gain is retained in normal volume control settingsMake sure always to include the feedback management presentation in any presentation for Ergo. It needs explanation and when properly explained it is one of the strongest selling features.
28Feedback management Ergo vs ordinary HF cut system In an initial fitting both systems can usually match a target gain with vc at the normal listening position 3HF cutThe presentation compare two different feedback management techniques - the Ergo and a HF cut which is the only other ‘feedback’ management system used in other linear analog instruments ( DFS from Danavox excepted). The HF cut is the sytem used by Siemens Swing, Starkey sequel and Phonak PICS in addition to PrimoFocus Pro II and CommuniCare !22P.What this slide shows is that with a modern programmable instrument, a reasonably good fit to a target gain can usually be achieved. Given that a comfortable fitting which also takes account of occlusion is also required in addition to matching target, then assume that for a sloping HL such as this, a reasonably large vent is also required.What this slide shows is that most instruments can hit the target insertion gain with the volume control at 3, giving 10dB reserve gain. No problems.
29Feedback elimination - two techniques When the vc is increased to 4, instruments often feedback.This feedback can be eliminated by activating the feedback manager or the HF cut.ErgoHF cutThen the Volume control is turned up to level four. Feedback can often be the result, especially if a large vent is selected in order to improve sound of own voice and eliminate occlusion problems. For ordinary instruments dispensers can deal with this problem by activating the HF cut. The alternative is to reduce the vent - which in turn can lead to more occlusion problems. The feedback can also be elimated by activating the Feedback Manager in Ergo. In both cases, high frequency gain will be reduced.
30Feedback management vs Feedback elimination The vc is then returned to 3.Ergo’s frequency response is back on target.For the HF cut instrument, there is a substantial deviation from target.ErgoThe problem with using a HF cut to eliminate feedback can be seen when the volume control is returned to level 3. Here, the HF cut the instrument is off target. Here, essential high frequency amplification is lost and will be lost for all volume control settings. This approach removes gain from the area where the hearing impaired user needs it most - from the area where the hearing loss is gretest. Is is also gain in this area which is most needed to give speech understanding especially in situations where the VC is reduced because of the overall noise level.With Ergo it returns and hit the target gain. The reason is that Ergo only cut high frequencies above the level at which the feedback manager control is set. If the feed back manager is set to level 3.6 high frequencies are only cut with volume control above 3.6.Now you can demonstrate that the instrument will not whistle at any volume control setting.Furthermore it is important that with a traditional HF cut system the client will loose high frequency amplification also when the volume control is set at lower levels. That have serious implications for speech understanding especially in noisy environments - which is where the client will have the volume turned down low. Here the high frequency amplification (the consonants) is necessary.HF cut

41Swift Product Concept Highest value low priced hearing aid ReliableGood sound qualityEasy and quick programming and fittingEasy to use and handleProgrammable alternative to low priced analog instrumentsSwift was designed to offer a significantly higher level of reliability than any other instrument in its class.It has a low level of distortion and circuit noise which contribute to an experience of good sound quality for the wearerProgrammingIt is important to stress that Swift as its name suggests was designed for quick programming. To achieve this, the programming is very straight forward and the software makes most of the decisions relating to the setting of the instruments. All the fitter has to do is to enter the audiometric data and the instrument is already set to a NAL target. Fine tuning involves two trimmers. The aim is for the fitter to avoid spending large amounts of time making very small adjustments to a large number of parameters.The advantage to the wearer is that they can now be accurately fitted with a low distortion reliable instrument for the same cost as for low performance analog instruments.
