of occlusion. This technology is called OpenEar
Acoustics and it makes a major difference in
the way hearing aids can be built. Thanks to
this technology, Adapto and Gaia hearing aids
can be fit with spacious ventilation channels that
allow natural sound to come in and body-transmitted
sounds (like talking and chewing) to escape
without the risk of whistling.
Both In-The-Ear (ITE) styles and Behind-The-Ear
(BTE) styles have large vents. Perhaps the most
important benefit of these vents is that they make
one’s own voice sound more natural. Additionally,
they act like a mini air conditioning system, ensuring
optimum air circulation inside the ear canal for
ventilation.
With conventional hearing aids, larger vents almost
always result in whistling, but Oticon’s advanced
signal processing addresses this problem. OpenEar
Acoustics delivers clearer, more natural sound,
exceptional use of remaining hearing, and a
reduction or complete elimination of annoying
whistling.
