www.siemens.com/binax . The world’s first technology that outperforms normal hearing. Information for Hearing Care Professionals. Life sounds brilliant. Binaural redundancy A few of the most important binaural processes include binaural redundancy, binaural squelch, and binaural directed listening. monaural Binaural directed listening binaural Binaural squelch monaural binax technology also sets new benchmarks for wearer convenience. Now for the first time, wearers have the possibility to remotely control any binax hearing instrument regardless of size, and without having to carry around an extra gadget. To localize sound sources, maintain spatial orientation, and understand speech better, our brain utilizes information from both ears. This is especially helpful in noisy and challenging listening situations like restaurants or parties. binaural A well-fit pair of hearing instruments is a good start towards restoring binaural hearing. But in challenging listening situations, this is not enough. binax™, the next generation of BestSound™ Technology, simulates the effects of binaural hearing and brings these advantages back to the wearer. It is so powerful that for the first time, wearers can understand speech in demanding environments even better than people with normal hearing.* The effects and advantages of natural binaural hearing. monaural As we continue to raise the standard of Soundability™, we always draw inspiration from the healthy auditory system. There are good reasons why we have two ears. Binaural hearing increases loudness, enhances clarity, and adds richness and superior quality to sound. However, the benefits of binaural hearing deteriorate with age and hearing loss. Binaural hearing means better hearing. binaural Opening up a new dimension of hearing: Our brain combines the input from both ears to create a central perception that is better than the individual signals. Binaural squelch enables our brain to clearly separate a speech signal from background noise and to give it more prominence for better speech understanding. With binaural directed listening, our brain can focus on one specific sound source while suppressing all others – even when there is a mix of many sounds. * Two clinical studies have shown that binax provides better than normal hearing in certain demanding environments (University of Northern Colorado, 2014; Oldenburg Hörzentrum, 2013): Speech Reception Thresholds (SRT) in cocktail-party situations improved up to 2.9 dB for wearers with mild to moderate hearing loss using Carat binax or Pure binax hearing aids with narrow directionality, compared to people with normal hearing. 3 High Definition Sound Resolution for the best binaural listening experience ever. binax: Outperforming normal hearing – with minimum power consumption. In order to emulate natural binaural listening, we first need to link the two hearing instruments, just like the brain uses input from both ears. Building upon the original e2e technology, which won the prestigious German Future Award in 2012, e2e wireless™ 3.0 enables exchange of audio signals between two hearing instruments. This virtual eight-microphone network provides a heightened sensitivity of the acoustic environment: We call this “High Definition Sound Resolution” or HDSR. HDSR is the basis for the binax features that offer an exceptional binaural listening experience. In fact, HDSR is so powerful that binax hearing instruments are clinically proven to allow wearers to hear in cocktail-party like situations even better than their normal hearing counterparts.* As a result, the hearing instruments not only use the information picked up by their own two microphones, but also the acoustic signal from the two microphones of the other hearing aid. This way, each hearing instrument works with input from four microphones. So together as a bilateral pair, these hearing aids create a virtual eight-microphone network. What’s more, this outstanding hearing technology is incredibly energy efficient. While providing outstanding HDSR, the revolutionary e2e wireless 3.0 technology requires just 1.6 mA with all binaural features active. As a result, all binax features – binaxFocus, binaxSound, and binaxGuide – can be engaged automatically and as often as necessary to offer the best binaural listening experience ever, without compromising battery life. * See legal note on final page in this document. e2e wireless 3.0 creates a virtual eight-microphone network. binax top technological facts: e2e wireless 3.0 transmits 1,000 x more data per second than the previous generation Advanced binax features for a new level of Soundability. binaxSound binaxGuide binaxFocus New: e2e wireless 3.0 transmission of audio signals 16 % more transistors than micon 20 % more instructions per second than micon 48 channels, 12 kHz of bandwidth Power consumption: Only 1.6 mA with all binaural features active 4 The combination of HDSR with low power consumption enables three binax key features: binaxFocus, binaxSound, and binaxGuide. Together, these features create the perfect equilibrium between sound quality and audibility for each individual wearer – raising the bar for Soundability. 5 binaxFocus. Opening up a new dimension of audibility. Narrow directionality Spatial SpeechFocus Automatic focus on main speech source Normal hearing Standard microphone technology Narrow directionality binaxFocus’ narrow directionality automatically focuses on the speaker immediately in front of the wearer. It is able to narrow the beam of the directional microphone and to help wearers understand speech in noise. In fact, clinical studies have shown that narrow directionality is so effective that it allows users to understand speech better than those with normal hearing in situations like cocktail parties.* Spatial SpeechFocus™ automatically focuses on the main speech source – be it from the front, back or even sides – while at the same time attenuating noise from other directions. It is automatically activated as soon as a car situation is detected. * See legal note on final page in this document. Watch the video on binaxFocus’ narrow directionality here: 6 Hearing that is more precise than ever. Environments with a lot of background noise have always been a challenge for wearers of traditional hearing instruments. With binaxFocus’ narrow directionality, wearers can fully enjoy a superb binaural listening experience, even in noisy places like restaurants or parties, and immerse themselves in conversations without a second thought. Watch the video on binaxFocus’ spatial SpeechFocus here: Understanding everybody clearly – from all directions. Wearers of traditional hearing aids can find it hard to focus on speech when it comes from different directions. binaxFocus’ spatial SpeechFocus highlights speech, regardless of direction, while suppressing background noise – even in cars. binaxSound. Opening up a new dimension of sound quality. eWindScreen binaural binax fit Input eWindScreen binaural Left freq. Right freq. Replacement Output Challenging windy situations Left freq. binaxSound continually monitors both hearing instruments and strategically uses eWindScreen™ binaural when wind is detected to transmit audio signals from the side with the better sound quality to the other ear. Watch the video on binaxSound’s eWindScreen binaural here: 8 Thanks to HDSR, unmatched spatial awareness is maintained. Additionally, binaxSound’s eWindScreen binaural preserves a high level of sound comfort – even in the most difficult windy situations. Right freq. Intelligent audio data exchange for the best possible sound: binaxSound replaces the inferior audio signal with the better audio signal. As is often the case with binaural features that involve streaming of signals from one side to another, a sacrifice has to be made in terms of spatial sound perception. So the challenge is to design hearing instruments with binaural features that offer the benefits of improved audibility without sacrificing sound quality – in this case, spatial sound quality. This is the purpose of binax fit. Building upon the success of micon™ fit and micon compression, binax fit follows the same strategies for frequency shaping and compression setting. It also takes into account the effects of automatic features both monaural and binaural, so that they work in concert to promote sound quality and audibility. This way, binax fit not only ensures that the sound impression of the binax hearing instruments stays natural and consistent. It also makes sure that all features maintain spatial cues at all times. Only the best audio output. Being outdoors on a windy day often means annoying wind noise for wearers of traditional hearing instruments. Thanks to binaxSound’s eWindScreen binaural, wearers will always maintain natural spatial awareness and optimum listening comfort – no matter how windy the environment. 9 binaxGuide. Opening up a new dimension of individuality. Automatic setting Spatial Configurator: Span Automatic setting Spatial Configurator: Direction Manual override Manual override Manual override Individual adjustment of direction Manual override Manual override Individual adjustment of span As an addition to automatic functions that adapt to changing acoustic environments, spatial Configurator empowers wearers to take control of how and what they want to hear. Watch the video on binaxGuide‘s spatial Configurator here: 10 They can individually adjust the span of their directional microphone focus beams, and decide how much of their environment they want to hear. Spatial Configurator also gives wearers the ability to indicate the direction of where their microphones should be focused – the front, the back or even the sides. Completely personalized hearing. Even the smartest hearing instruments won‘t be able to know how the wearer wants to hear all the time. binaxGuide’s spatial Configurator enables wearers to temporarily override their automatic hearing instrument settings in unique listening situations. So they can decide how they want to hear. This offers wearers the most individual binaural hearing experience available. 11 Opening up a new dimension of sound: Our product portfolio.
