Abstract: A method of manufacturing hearing devices comprising an otoplastic individually shaped for a user includes providing input data for each set of input parameters of an algorithm for determining target data for each of a set of target parameters, wherein at least a portion of said input data are individual to said user, and wherein said target parameters are parameters related to the geometrical and/or acoustical properties of a hearing device. The target data is determined by applying the algorithm to the input data. A suitable three-dimensional shape of the otoplastic is designed in dependence of the target data by means of otoplastic modeling software. The otoplastic is manufactured according to the suitable three-dimensional shape. Property data descriptive of properties related to the manufactured otoplastic are obtained using the otoplastic, and the algorithm is amended in dependence of the property data.

Abstract: This invention relates to an impression-taking pad (10) for taking an impression (20) of an ear canal (30) by an impression-taking material, having a lateral end (el) to be arranged away from a tympanic membrane (35) in said ear canal (30); and a medial end (em) to be arranged proximate to said tympanic membrane (35). The impression-taking pad (10) comprises an outer body (2) tapering from said lateral end (el) to said medial end (em).

Abstract: An antenna module for a hearing device includes a hollow core provided with an axial passageway and a winding around the core which is connectable with a hearing device. The antenna module is arranged to be at least partially contained within the ear canal of a user. This enables the antenna to be separated from sources of interference, since it can be positioned inside the ear canal away from hearing device electronics, thus reducing requirements for shielding and/or compensation. The invention further relates to an ear tip and a hearing device including such an antenna module.

Abstract: An ITE hearing aid having a shell worn at least partially in a user's ear canal, a faceplate closing the shell at a side oriented towards the exterior of the user's ear, and at least one microphone housed in the shell and acoustically connected to ambience via a sound port formed in the faceplate. The faceplate has a cover element covering a cavity of the sound port in a direction normal to a main plane of the faceplate and a lateral sound opening in a wall extending normal to the main plane. The cover element is elevated above a surface region surrounding the cover element, with the sound port wall extending between the cover element and this surface region. The shell is designed, with regard to shape and size, in a manner that the hearing aid is manually removable from the ear canal without the need to use a tool.
