Abstract: The method for reconstructing the three-dimensional shape of the surface (14) of at least a portion of an ear canal (18) and/or of a concha comprises—for each of a multitude of points (12) on said surface (14)—the step of using a chromatic coded distance measurement technique for determining a distance value (40) representative of a distance to said point (12); and further comprises the step of reconstructing said three-dimensional shape based on said multitude of distance values (40).

Abstract: 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.

Abstract: The invention relates to a hearing protection earplug (10) to be worn at least in part in a user's ear canal, comprising a shell (12) 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 (20, 30, 120, 144, 220, 320, 420) 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.
