Conductive Loss: Patient VT, Right Ear
The Alpha System™ can be used by any age patient. This graph show examples of results typical with the Alpha 1™ magnetic hearing system. Note that the unaided free field thresholds are better than the air conduction thresholds as these patients had normal hearing in the non-implanted ear and the masking was not perfect.
Typical Results
This table outlines typical results for patients with monaural and binaural conductive loss as well as mixed loss. Averages are computed from 500, 1000, 2000, 3000 and 4000 Hz.
