The method for reconstructing the three-dimensional shape of the surface () of at least a portion of an ear canal () and/or of a concha comprises&#x2014;for each of a multitude of points () on said surface ()&#x2014;the step of using a chromatic coded distance measurement technique for determining a distance value () representative of a distance to said point (); and further comprises the step of reconstructing said three-dimensional shape based on said multitude of distance values (). The system for reconstructing the three-dimensional shape of the surface () of at least a portion of an ear canal () and/or of a concha, comprises a distance measurement unit for determining&#x2014;by means of a chromatic coded distance measurement technique and for each of a multitude of points () on said surface ()&#x2014;a distance value () representative of a distance to said point; and a reconstructing unit () operationally connected to said distance measurement unit for reconstructing said three-dimensional shape based on said multitude of distance values ().

Method and system for reconstructing the three-dimensional shape of the surface of at least a portion of an ear canal and/or of a concha

A body-worn device, such as a hearing aid, is adapted to the shape of an individual's body area, such as an ear. A digitized, three-dimensional representation of the area is prepared. At least one characteristic feature of the representation, such as a dimension of a part of the ear, is automatically determined. A shell is produced based on the characteristic feature. The body-worn device is assembled with the shell.

Method for manufacturing a body-worn electronic device adapted to the shape of an individual's body area

The invention relates to a hearing protection earplug () to be worn at least in part in a user's ear canal, comprising a shell () having a outer surface individually shaped according to the measured inner shape of the user's outer ear and ear canal, and a functional member () engaging said shell in a manner so as to be movable relative to said shell between a first functional position and a second functional position, said shell and said functional member having been produced by an additive layer-by-layer build-up process and having an elasticity of between shore D85 and D65.
