For example, data relating to the circumference of the face plate may be provided to a numerically controlled machine that automatically cuts a separately manufactured face plate along the desired contour that matches the circumference of the corresponding shell. In anothe r embodiment, the hearing aid housing is manufactured with an integrated face plate. The invention further provides a hearing aid. |
