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 hearing device having at least one of an acoustical/electrical converter and an electrical/acoustical converter respectively with an acoustical input or output. The input or output, as the case may be, is linked to a coupling opening at the outer surface of the device via a channel. At least a part of the outer surface of the device is formed by a one-part shell. The shell defines an inner space of the device, with the channel being provided within and along the part of the shell and being formed within the material of the shell.

Method of manufacturing an ear plug device with embedded venting grooves formed in its outer surface

An in-the-ear hearing device comprises an outside body, which is at least in part of textile material (). The textile material allows to optimally adapt shape and shape dynamics as well as biocompatibility to the respective characteristics of an individual ear canal.

In-the-ear hearing device

Hearing device with embedded channnel

A hearing device and process for its updating, including a resilient outer shell and one or more internal units, with the outer shell conforming in shape to at least one of the internal units so that the internal unit is held snugly in place. The outer shell can be replaced using either a destructive or non-destructive disassembly method to re-use at least one of the internal units.

Custom-molded ear-plug, and process for producing a custom-molded ear-plug device

A hearing device for inserting into or adjacent to the ear of an individual. A shell is custom-shaped to fit the individual. The shell is made mainly of a first material and includes a part made mainly of the first material. The part has an inner surface. A pattern of embossments or indentations is provided in the inner surface. The pattern is made out of the first material. The pattern represents an individualized identification code of the part or the device. The pattern is generated concurrent to the manufacture of said part. The pattern can be generated using a laser sintering process, a laser lithography process, a stereo lithography process, or a thermojet process.

Custom-moulded ear-plug, and process for producing a custom-moulded ear-plug device

A hearing device is manufactured for an individual based on: information about individual audio needs, information about a three-dimensional shape of the application area for the hearing device, information about individual non-audio needs of the hearing aid device, and information about the feasibility of hearing devices; thereby creating a three-dimensional visualization of the device controlled by the individual, and creating data defining the visualized device for subsequent realization of the device.

Method for manufacturing hearing devices

A hearing aid ear-plug device and process for its manufacture, including a resilient, custom-molded outer shell adapting to the dynamics of its area of application including the ability to adapt to dynamic movement of the auditory canal. The outer shell may include fins and/or ribs integrated internally or externally with the shell. Any internal components of the device are protected while ensuring the structural stability of the device.

Custom-moulded ear-plug device

A process for manufacturing custom-moulded ear plug device, such as in-ear hearing aids used in an area subject to dynamic and individually different movements. A three-dimensional image of an area of application of the device is taken at two or more positions of movement. Data from the images are used to design the outer contour of the device for optimal fit and performance.

Production process for custom-moulded ear-plug devices

A hearing aid device and process for its manufacture, updating, and/or repair including a resilient outer shell and one or more internal units, with the outer shell conforming in shape to at least one of the internal units so that the internal unit is held snugly in place. The outer shell can be replaced using either a destructive or non-destructive disassembly method to re-use at least one of the internal units.

A device and process for uniquely identifying customized hearing aids and hearing aid parts. The device and process is also useful for facilitating the manufacture of a customized hearing aids and customized hearing aid parts by uniquely identifying the parts as belonging to a particular individual. Thus, the device and process ensures that hearing aids designed for a particular individual is properly and uniquely identifiable.
