One of the most common complaints of older technology was the Occlusion Effect.  This was a source of irritation for both users and hearing care professionals alike.
For many years,it was an unfortunate side-effect, but now with OpenEar Acoustics™ the occlusion effect can be eliminated or reduced – without feedback. In addition to reducing or eliminating occlusion, this system preserves the important characteristics of more natural hearing, making it easier for first time users to adapt to their new hearing aids. OpenEar Acoustics™ is made possible by the patented Dynamic Feedback Cancellation system, short processing time and low frequency gain compensation, permitting substantially larger venting. The result is an extremely effective system for reducing occlusion, without annoying feedback.
