the platform for Natural souNd

C-ISP communication platform

clear440 is a unique hearing aid – powerful on its own but strongest when coupled. The c-ISP commu-nication platform in clear440, with a total of three individually designed chips, makes this new power possible.

The natural next-step in the evolution of hearing aid platforms, it is devised to open the signal processing to input from a coupled hearing aid and take inte-grated signal processing to a new level.

This new c-ISP technology takes its cue from our acclaimed ISP platform. like its predeces-sor, c-ISP combines and manages a series of sound analysis and processing functions for clearer hearing. What’s different is its capacity for continual adjustment of discrete hearing aid functions both within hearing aids and between them – what we call Interear. The result is an un-equalled balance of performance that replicates the natural hearing experience even more closely.

• c-ISP ensures interaural coupling of the hearing aids. a clear440 hearing aid will perform strongly on its own, and even better as part of a pair.

• c-ISP allows connectivity to external sound sources – with seamless streaming in enhanced sound quality.

In short, c-ISP allows clear440 to coordinate fea-tures, calibrate decision-making and communicate to the user.

the technology for Natural souNd

WidexLink™ – the timing is right

Natural sound was the inspiration for clear440. Our next challenge was to develop a robust wireless link to facilitate

seamless communication and coordination between hearing aids – the best possible premise for natural sound.

Widexlink is the exclusive result.

The first, full-feature wireless link – designed especially for hearing aidsProprietary Widexlink™ is a wireless, high-speed data transmission technology that allows instant, ongo-ing communication between hearing aids and direct connection to external audio devices. Because of its speed and robustness, Widexlink allows instant syn-chronisation and coordination between hearing aids. This not only enables technologies to work effectively in one hearing aid – more importantly it ensures that a coupled pair of clear440 hearing aids have great potential in regard to sound quality and enjoyment of different sounds.

It also lets the user remotely manage a selection of features in the hearing aids simultaneously. and Widexlink allows high definition audio streaming between hearing aids and from discrete external audio inputs like a mobile phone, tele vision or radio.

real sound in real time

The Widexlink system is not only an accurate, high-speed delivery route, it is also an intelligent coding and decoding system that bundles and unbundles data bursts effectively. any missing or misinterpreted data is anticipated and corrected automatically.

This means there’s no need to retrieve a new signal – which ensures important analysis and processing communication is never impeded. and processing can be adjusted binaurally without delays or lags.

Seamless connectivityIn addition to inter-hearing aid communication, Widexlink solves a number of other challenges that have limited efficiency of hearing aids and accesso-ries until today:

• Transmitting from external sources – high definition hearing and control: Widexlink provides a high-speed and robust direct transmission for use with external devices such as a remote control, direct TV link and direct cell phone link. Its coding/decoding capabilities and signal strength ensure no loss of audio information, and consequently clearer sound in perfect synch with imperceptible audio delay.

• connectivity that lasts – Widexlink technology en-sures battery efficiency due to an efficient coding algorithm and our proprietary receiver technology. This minimises delays and disruptions for users, letting them enjoy their TV or cell phone for longer periods.

• Interear Partner Monitor – protecting the user’s investment in hearing: Because Widexlink allows hearing aids to communicate with each other up to 21 times per second, any disruption to that connec-tion produces an instant alert triggered by the Widexlink surveillance system. If one hearing aid loses contact for any reason, the user will know instantly.

Interear data

Up until now it has been difficult to truly reap the benefits of near-natural sound in two hearing aids linked together.

Our solution is the unique Interear or Ie. This ensures both coordination and synchronisation seamlessly.

Interear also ensures that the hearing aids communicate with each other up to 21 times a second, resulting in instantaneous near-natural sound in both.

The WIdex clear™440 models add new dimensions to signal processing, taking users closer to a natural sound experience that is audible, comfortable and understandable.

The development of clear440 signal process-ing was inspired by fundamental characteristics of normal hearing; for instance, the ability to single out a distinct speaker and to use the Interaural level dif-ference.

Our aim has been to exploit the potential of Widex-link to add a new dimension in processing. We call this 3d TruSound.

3d TruSound is natural sound perception and sound quality.

clear440 offers a vast range of new and exciting audiological and sound features. While each is unique on its own, together they are formidable.

souNd perception

Ie Speech enhancer – clearer sound in noiseNormal hearing listeners have the ability to focus on a speaker in a noisy environment and single them out. With a hearing loss, this ability is often compromised.

To meet this challenge, Widexlink makes it pos-sible to exchange significant percentile information about the type and level of input signal in each of the 15 processing channels of clear440. We call this Interear Percentile exchange.

The coordinated speech enhancement algorithm – Ie Speech enhancer – exploits the binaural percentile information to enhance speech above the threshold and attenuate background noise below it. In this way, coupled clear440 hearing aids attempt to single out a dominant speaker in background noise.

Interear TruSound compressionThe figure illustrates the level at the eardrum for the right ear and the left ear and the resultant Interaural level difference (Ild) when sound arrives from the right side of the head. The graphic compares three situations: normal hearing, coordinat-ed compression and uncoordinated compression. The essence is that the Ild for the normal hearing situation and the Ild for the coordinated compression are identical.

Normal Coordinated

Ie TruSound coordinated compression– extending the power of edrcThrough Widexlink, the Ie TruSound compression system can now exchange data in a coupled pair of clear440 hearing aids.

Ie TruSound compression amplifies soft, normal speech and loud inputs through an adaptive gain algorithm. Inspired by the theory of Interaural level difference, a prerequisite for sound source localisa-tion, Ie TruSound compression optimises the gain adjustments and overall output.

This inter-ear coordination means that a louder input level in one ear can guide the compression settings in both hearing aids in a binaural fitting.

digital Pinna effect – helps locate sound from any direction

It is well established that Behind-the-ear hearing aids disturb the natural pinna effect created by the outer ear. consequently, sounds reaching the ear directly from the front or back may be perceived as coming from exactly the same direction – and thereby make it difficult for hearing aid users to know the location of the sound source.

The Hd locator of the clear440 hearing aid is now expanded to include a digital pinna – an electronic pinna characteristic that recreates the natural shad-owing effect of approximately 4 dB to achieve a more natural front focus.

Ie volume control and program shift – instant synchronisation

The Interear volume control and program shift in clear440 ensures that if the user changes the volume on one hearing aid, the volume of the other hearing aid will change accordingly. Similarly, if they switch programs on one hearing aid, the appropriate program will be chosen automatically by the other hearing aid.

clear440 offers a broad selection of program pack-ages tailor-made to satisfy different user needs.

Ie Feedback cancelling – minimises whistling

Widex high-end hearing aids today all feature a multi-directional adaptive feedback cancelling system that minimises whistling. In clear440, an even more precise system is incorporated, coordinating informa-tion on feedback occurrence between both ears.

The potential in Interear data exchange is to make the Ie Feedback cancelling more agile in handling acoustic feedback in situations where the acoustic property of the feedback signal resembles that of musical instruments.

TruSound SoftenerThe graphic shows the integration of the TruSound Softener in the signal pathway.

TruSound Softener – intelligent comfort

Transient noises like the chinking of porcelain or slamming doors, which are short in duration and oc-cur abruptly, have an unfortunate sound impact for hearing aid users. That’s why handling needs to be instantaneous and intelligent to ensure comfort and maintain natural sound quality.

The TruSound Softener detects quickly occurring sound bursts with a steep gradient detector. This enables new extreme accuracy, determining sound bursts as either speech or noise transient sounds. Once detected, any disturbing or irrelevant transient is handled by the TruSound Softener in clear440 TruSound compression via a swift forewarning algo-rithm.

enhanced bandwidth – a fuller sound

Hearing at its best allows us to enjoy as much of the frequency range as possible. clear440 supports the widest bandwidth currently available in a hearing aid, including an enhanced low frequency bandwidth for the full enjoyment of music.

The broad bandwidth achieved in clear440 is also important in supporting the detection of the high frequency cues necessary for localisation. This is fully realised in the clear440 clearBand model.

The WIdex clear™440 series includes powerful new features that let you customise the user’s hearing experience even more effectively. The fitting for the user can be customised to reflect their preferences, including tailoring options that give them greater control of their hearing in their daily lives.

the freedom of Natural souNd

Hearing as the listener prefers it

FreeFocus – control listening direction

Having the freedom to shift focus is a luxury not eas-ily given back to people with hearing loss. during the development of clear440, we paid special attention to this challenge.

27

FreeFocus in clear440 allows users to hear in selected directions – without them needing to turn their heads. clear440 offers both front/reverse and right/left focus via the Mobile dex (or M-dex) selection panel. reverse Focus is also available in a dedicated listening program.

Phone+The Phone+ feature processes and transmits phone signals from one hearing aid to the other without de-lay. This means that for the first time, users can hear mobile and landline phone calls in both hearing aids without the use of extra devices.

definable volume control – improved flexibilityThe ability to adjust volume and change listening programs is important to hearing aid users. Some users prefer to control volume in large increments; others prefer the precision of smaller steps. Therefore clear440 offers a choice between 1, 1.5 and 2 dB steps.

either way, clear440 can be programmed to offer the flexibility that works best for them.

Ie Zen – natural relaxation

Our popular Zen dedicated relaxation and tone program has been enhanced. Sound generation is distributed between the hearing aids (Interear) – some instruments in one ear, different instruments in the other.

Ie Zen also features the option of choosing a noise style, complementing existing well-known musical Zen styles. Zen styles can now also be predetermined with a timer option – making it easy to create specific relaxation or concentration time periods.

Ie Zen listening programs can be accessed using the program button, the rc-dex or the M-dex.

wireless fittiNg

Professional and precise

Widex fitting tools have always supported audiolo-gists throughout the world in performing close to optimal fittings. Professional fitting is also about hav-ing the right tools to meet the fine-tuning needs of the user. That’s why we have added new fitting tools important for exactly meeting your fitting needs.

29

Wireless fitting – reliable, secure, easy to use fitting

clear440 extends Widex’ renowned excellence in precision fitting by introducing wireless fitting. Fitting WIdex clear™440 hearing aids could not be easier. Widexlink technology means that once and for all you can do away with cables and connectors and are ensured a seamless and reliable fit from the outset. Widexlink is convenient, easy and intuitive to use, giving the professional more time to focus on attain-ing the best possible fit for the user.

Widex has adapted the industry standard (near-com and NOaHlink) to provide professionals with the ultimate security in wireless fitting situations.

Widex feedback test

The Widex feedback test is an essential and integral step in the fitting procedure. It provides an evaluation of the fit and/or sealing of the earmould and initialises the adaptive feedback cancellation algorithm. It also includes the assessment of In-Situ acoustics (aISa).

AISAaISa is an objective way to estimate the acoustic influence of the user’s vent and leaks around the ear-mould during the fitting of a hearing aid. We call this the in-situ vent effect. Once this has been mapped, the fitting algorithm will ensure that the gain setting of the hearing aid compensates for the in-situ vent ef-fect so that audibility and perception of loudness for amplified sounds are not compromised.

In-situ recdIt is well-known among audiologists that special measures are necessary to obtain the correct gain in the smaller-than-adult ear canal.

Many audiological professionals choose to make an actual measurement of the individual ear acoustics. This can be done measuring the real-ear-to-coupler difference (recd).

It is possible to use the hearing aid itself to measure the recd in-situ. Once the data has been recorded, compass will automatically include this data in the gain prescription.

dedicated new software tools

Widex meets the wishes of the dedicated audiolo-gist by introducing an expanded fine-tuning matrix in the gain settings panel. This expanded option gives you better possibilities of meeting users’ needs and improved interaction between you and the user in the fitting and fine-tuning situation.

Furthermore the fitting software now also features a global acclimatisation function for the comfort of your first time users.

30

Giving you more control in-situ

The Widex in-situ fitting strategy is designed to enable a precise and uncompromised fitting. With clear440, mapping and correcting for the subtle individual differences in the outer ear (ear canal) are easily performed with the hearing aid in-situ.

Sensogramaudiometric thresholds are often prone to con-siderable measurement errors: in particular, the uncertainty regarding the actual sound pressure level presented at the eardrum of an individual during audiometry.

The range of variation of sound pressure levels is in excess of 20 dB at the high frequencies.

Our efficient solution to this problem is the Senso-gram. This utilises in-situ audiometry, which takes into account the individual characteristics of the ear canal and the hearing aid.

The WIdex clear™440 series of hearing aids al-ready opens a whole new world of sound to their us-ers. and now with our unique dex assistive listening devices, designed for wireless communication, they can take advantage of the entire soundscape.

M-deX is a user-friendly and stylish wireless device for mobile (cell) phone applications. The integrated microphone in M-dex makes it possible to use it as a handheld, remote talk-and-listen device using the hearing aids as wireless headsets.

advanced hearing aid features in the clear440 hearing aid such as FreeFocus and wireless sound transmission directly to the hearing aids can be controlled from the intuitive M-dex user interface. The unique room Off feature allows the user to con-centrate on a telephone conversation without being disturbed by surrounding noise that would otherwise be picked up by the hearing aid microphones.
