For hearing aid users, conversations with background noise are a serious challenge. Things get even more complicated when several people are involved as normal hearing aids operate on a line-of-sight principle. Rexton Reach is now introducing Multi-Voice Focus with 4 focus beams that constantly scan the surrounding environment 1000 times a second, allowing it to focus on multiple speakers at the same time. It constantly adapts to the changing dynamics of the conversation by boosting the prominence of those in the group who are speaking whilst even reducing background noise.
Track and detect multiple voices in 180° - 1.000x/sec.
Activate new types of beams to reach speakers and follow them as they move
Separate target speech from background noise to process them separately
Voice Stabilizer is an update to the existing Voice Ranger.
When background noise gets louder SNR is compromised.
Voice Stabilizer controls the compression knee points to secure that all voices within the focus beam are amplified in the best linear ways.
The separate processing of speech (in different beams/streams) and noise allows for more aggressive compression of the noise and more linear (and stable) processing of the speech - ensuring a strong contrast between speech and noise.
SoundPro 3.0 automatically steers all sound processing features, including the new Multi-Voice Focus* inputs, based on the analysis of the acoustic scene. When changing the strategy to Natural Focus or Speech Focus, the recommended balance of features is modified. The Balanced Focus is recommended for enhanced automatic performance./n*only for 2-Mic devices and binaural fittings.
Traditional hearing aids classify listening environments into a limited number of situations because they are based on modulation and intensity of signal.
Multi-Voice Focus adds a new layer of reliable processing. SoundPro 3.0 is now automatically steering all the sound processing including localization of active talkers and their proximity, number of conversation partners, turn taking and timing.
And this whole analysis has, in parallel, a very robust binaural wireless link transmitting those processing info from one HA to another, to assure precise synchronizing.
The new Reach platform is ready for Bluetooth LE Audio – the next generation of Bluetooth Connectivity. It is especially relevant to the latest Android devices allowing headset mode and tap control (phone streams to HI and HI MIC streams back to phone; user can accept / terminate call on HI) with very low power consumption. This feature will be made available via firmware update in the near future.
