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 ( 140 _r# and 140 _l#) 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 ( 140 _r#) is digitally mirrored at the digital model of the sagittal plane (SP_#) resulting in a mirrored digital model ( 140 _m#). Then the other digital model of the application area ( 140 _l#) and the mirrored digital model ( 140 _mr#) are brought into best possible covering alignment ( 140' _l#). Units to be positioned in predetermined mutual relationship are applied to the models in best possible alignment.
