OpenEar AcousticsOpenEar AcousticsTM For new users of modern hearing instruments, one of the unexpected dis-appointments has been the distortion of their own voice i.e. the occlusion effect (Kochkin, 2000). There has been much discussion about the origins and effects of occlusion, but the reality remains that there is only one clinically effective method to reduce or eliminate occlusion; allow the low-frequency sounds to escape via the ear canal through increasing the vent size. Oticon's solution for this is called OpenEar Acoustics. OpenEar Acoustics can be applied to any of the fitting rationales in Gaia. To fully utilize the concept, the instrument offers: (a) a short digital processing time, (b) a digital feedback control and (c) low-frequency gain compensation.
