POSITIONING AND ORIENTING A UNIT OF A HEARING DEVICE RELATIVE TO INDIVIDUAL'S HEAD

摘要

Digital models of the application areas of a left-ear and of a right-ear hearing device are established. The models (140r# and 140i#) are displayed on a computer display. The location of the model (SP#) of the sagittal plane of individual's head is estimated with respect to one of the two digital mold models. Then that one digital model (140r#) is digitally mirrored at the digital model of the sagittal plane (SP#) resulting in a mirrored digital model (14CW) Then the other digital model of the application area (140i#) and the mirrored digital model (140mr#) are brought into best possible covering alignment (14O'i#) . Units to be positioned in predetermined mutual relationship are applied to the models in best possible alignment.
