Listening effort is reduced by making speech understanding easier. Contrast achieves reduced listening effort in a wide variety of speech environments. This is achieved by selectively activating and steering three key technologies in parallel: Noise reduction, directionality and now with Contrast, by steering amplification to target and elevate the dominant speaker over all other sounds in any environment. We call this SpeechMaster.

With Contrast, we introduced true binaural processing with e2e wireless 3.0 data transmission technology. In a bilateral fitting, e2e wireless 3.0 directly transmits audio signals between the two hearing aids. As a result, the hearing aids not only use the information picked up by their own two microphones, but also the acoustic signal from the two microphones of the other Contrast hearing aid. This way, each hearing aid works with input from four microphones. Together as a bilateral pair, they create a virtual eight-microphone network that causes a heightened sensitivity of the acoustic environment.

Thanks to narrow directionality and SpeechFocus, Contrast allows patients to focus precisely on their desired sound source, whether it comes from the front or behind. To the front, it can narrow the beam of the directional microphone so much that it helps patients understand speech in difficult listening situations.

Thanks to true binaural processing, Contrast ensures optimal sound quality – even in challenging situations. In the presence of wind, eWindScreen™ binaural strategically transmits audio signals from the aid with the better audio quality to the other ear. This effectively reduces the annoying effects of wind, without compromising spatial perception or speech intelligibility. eWindscreen binaural is available as an optional program in Contrast hearing aids.

Spatial Configurator is the easy user control by which the experienced patient can steer their hearing aids in unique listening situations according to their listening preferences. Span allows the wearer to control whether the hearing aids should focus on the speaker from the front, or pick up the soundscape from all around them. Direction allows the wearer to dictate to where the directional microphones should focus, whether it is the front or the back.

Ideal for patients with un-aidable hearing loss in one ear: CROS and BiCROS solutions are based on e2e wireless™ 3.0 with its industry benchmark for low energy consumption.

A CROS RIC transmitter is worn behind the un-aidable ear and the sound it receives is sent wirelessly to the Contrast hearing aid on the other side, thus allowing the wearer to hear sounds from both sides.
