Abstract

The aim of the invention is to produce shells for in-ear hearing aids which are to be adapted very precisely to the individual auditory canal shape. To this end, a mould is made of the individual auditory canal and a hearing aid shell is created using an additive construction technique such as laser sintering, stereolithography or the thermojet technique, which is controlled with the mould data.

Claims (6)

1. A method for producing in-the-ear hearing devices, in which .cndot. a mold in the shape of the individual auditory canal is made, .cndot. a hearing device shell corresponding to the mold is produced, .cndot. functional parts of the hearing device are installed, wherein the shape is digitized in 3D and the hearing device shell is thus created by an additive construction method, in which one sectional layer after the other is deposited on top of one another, characterized in that firstly sectional layers of a plurality of individual hearing device shells are respectively created virtually in parallel, before the following sectional layers of the individual hearing device shells are deposited on already created layers in the additive construction method.
2. The method as claimed in claim 1, characterized in that an impression is taken of the auditory canal, is scanned and the scanning signal is digitized.
3. The method as claimed in one of claims 1 or 2, characterized in that the digitization of the shape is performed at distributed front centers, the data corresponding to the mold are transmitted to a production center, where at least the hearing device shell is created.
AMENDED SHEET
4. The method as claimed in one of claims 1 to 3, characterized in, that laser sintering, stereolithography or a thermojet method is used as the additive construction method.
5. An in-the-ear hearing device with a device shell, characterized in that it consists of solidified thermoplastic material.
6. The method as claimed in one of claims 1 to 5, characterized in that a plurality of hearing device shells are created virtually in parallel.
