A clear connection to people
Beltone LINQ brings people together. Clear sound, focused on the spoken word without annoying distortions, puts hearing impaired people clearly back in the picture.
Always focusedBeltone LINQ’s adaptive directionality correctly identifies the surrounding environment and targets the speaker. It updates itself 750 times per second and automatically adjusts to reduce torso, shoulder and head sound diffraction effect. This multi-dimensional polar plot continuously focuses on frequency-specific noise sources to enhance the directional beam.
Always clearTo provide an even clearer sound, Beltone LINQ incorporates SPDExtra, a new modulation-based noise reduction system. Activated over Beltone LINQ’s 9 channels, SPDExtra operates quickly to reduce irrelevant background noise in those frequency areas where no speech is detected. The result is better communication in the form of more comfort with less listening effort.
Whether sitting around a dinner table with family, having a quiet conversation with a spouse, or walking down a crowded street talking to a friend, Beltone LINQ will help users connect to the people in their lives.
The diagram above illustrates how Beltone LINQ’s adaptive directionality attenuates concurrent multiple noise sources. The dark red color represents the front of the user. The blue color represents the area towards the back of the head. In this simulation, two noise sources were simultaneously attenuated: distant traffic noise at 500Hz directly behind the wearer (180°) and a whistling tea kettle at 3300Hz on the user’s left (270°). The position and depth of the indentations illustrate the flexible nature of Beltone LINQ’s directional system.
- Ability to focus: Adaptive directionality, effective at all frequencies, enhances those frequencies with high speech content while attenuating multiple noise sources.
- Clear signal: Precise and up-todate modulation analysis identifies frequency areas with poor signal-to-noise ratio.
- No distractions: Selective and fast noise reduction feature over 9 channels lessens irrelevant background noises.
The diagrams above show how two Beltone LINQ hearing aids process the same speech mixed with traffic noise. The SPDExtra feature is only activated in the right instrument. It is thus clear that the SPDExtra reduces the general amount of noise (red areas in the low frequencies and overall green/yellow areas) while leaving speech formants (red areas in the mid-high frequencies) unaffected.
