audifon, Kölleda
audifon avacio – one of the smallest BTE hearing aids a with 2-microphone system

With the new avacio, audifon is continuing its tradition of manufacturing one of the smallest BTE hearing systems in the world – because along with functionality, many customers attach importance to an attractive design. Apart from a pleasant design, audiofon avacio is equipped with a 2-microphone system for optimising directional hearing. Using the audifit fitting software, the system can be programmed to switch between either an omnidirectional or a directional microphone, or between an omnidirectional microphone and telecoil. audifon avacio's signal processing is based on an up-to-date, high-resolution digital sound processor (DSP) using four channels and adaptive 128-band noise reduction. The audifon avacio satisfies the highest auditory requirements. The combined DSP and directional microphone system optimises speech intelligibility in noise or offers precise sound impressions from the environment in its entirety. Thanks to its adaptive feedback suppression, the audifon avacio supports a wide fitting range, which makes for high flexibility in hearing aid fitting – even for open fittings.


Audio Service, Herford
Luxor 1 and Monza – top quality in every price segment

The new Luxor 1 hearing system is top-class in Audio Service's product range. Four feature groups offer rapid and optimum fitting, further improved speech intelligibility, natural loudness perception and perfect user-friendliness. Luxor 1 guarantees optimum hearing comfort.

Audio Service also presented TRC (Twin Ratio Compression), an innovative concept for natural loudness perception. Using two variably adjustable compression ratios for dynamic compensation, TRC allows close approximation to normal loudness perception. This means more natural hearing and improved speech intelligibility for the customer.

Offering a particularly attractive price-performance ratio, the Monza 1 and Monza 2 hearing systems are now available in the mid-range segment.

The new amplifiers are combined with two new BTE housing variants.

The three systems are equipped with Push-Scroll, an entirely new kind of patented control that combines the functionality of a digital volume control with the options of a program pushbutton.


Interton, Bergisch Gladbach
BIONIC technology – better quality of life thanks to better speech intelligibility

With BIONIC technology, Interton was presenting an absolute innovation concerning speech intelligibility. Due to cutting-edge linear signal processing, the hearing aid user can hear speech much better, even in background noise. The technology used results, for instance, in a highly optimised signal-to-noise ratio.

The BIONIC NanoTwin open hearing system, available now with a thin and unobtrusive sound tube, also benefits from BIONIC technology. The highest wearing comfort and an option for open fittings are guaranteed.

BIONIC ShapeTwin, the new design hearing system, is equipped with an external receiver, which makes for an exceptional hearing solution. An innovative approach permits combining the receiver with an individually shaped earmould. Apart from that, it is possible to clip the external receiver into the otoplastic, which is highly convenient and user-friendly.

Interton has an innovation in fitting software to offer: CompuFit 4, which can be used for all Interton hearing aids, facilitates fitting and fine-tuning.


Oticon, Hamburg
SAM – patented innovation in hearing aid fitting

At this year's EUHA Congress, Oticon was presenting a world-first in hearing aid fitting. The patented Sound Activity Meter (SAM) developed by the Danish company succeeds in taking into account for hearing aid fitting data that are usually not available. SAM enables the hearing aid acoustician to consider the client's individual auditory lifestyle. The measuring device is only two centimetres long and can be worn on the lapel. Within I few days' time, SAM analyses the wearer's personal auditory environment, thus permitting precise and individual fitting. With SAM, Oticon is paving the way for an entirely new dimension in hearing aid fitting. Combined with Oricon's intelligent Syncro hearing systems, this is the basis for an excellent fitting.
