  • Patent number: 8238565
    Abstract: A system for adapting a hearing aid to a user includes a unit generating an image of the user's ear together with a model of the hearing aid, wherein the model of the hearing aid in-situ includes a physical model of the hearing aid inserted in the user's ear prior to generating the image. The system also generates a mesh based on the image, calculates acoustic response to a simulated acoustic signal in the mesh, calculates a frequency response curve for a fixed position in the mesh, and identifies an optimal position of a microphone of the hearing aid in-situ from the acoustic response. They system also includes a comparator configured to compare the frequency response curve for the fixed position in the mesh with a maximum frequency response curve for the mesh stored by the system.

  • Patent number: 8233649
    Abstract: With a hearing aid device which can be worn in the ear, a barometric pressure equalization which is needed for the sound transducer, such as a microphone or receiver, is to be achieved in a simple and cost-effective fashion. To this end, a converter protection facility is proposed with a membrane, with a pressure equalization channel, which connects a sound channel to the interior of the hearing aid device, extends through the transducer protection facility at least in one section. Replacing the transducer protection facility thus also replaces this subsection of the pressure equalization channel. A possible blockage of the pressure equalization channel which exists in this region as a result of dirt or moisture is eliminated as a result.

  • Patent number: 8218803
    Abstract: In the case of a receiver facility to be fixed in the auditory canal, particularly for hearing devices with an external receiver, the receiver is to be mounted in the earmold in an acoustically advantageous fashion which guards against contaminations and is also easily exchangeable. Provision is thus made for a receiver facility with a longish receiver and a earmold, which has a borehole, into which the receiver is inserted. A tubular connector, which is more elastic than the receiver and the earmold, is used to accommodate for the most part the longitudinal extension of the receiver in a friction-locking fashion. The connector is for its part force-fitted into a borehole of the earmold in a friction-locking fashion. The receiver is thus elastically mounted and can be easily removed from the earmold together with the connector with the aid of a pin-like tool for replacement purposes.

The housing (G) and any protective devices (K) which are to protect from contamination, are provided with a dirt-resistant layer. In this way, the dirt adheres less strongly to the hearing aid, so that if necessary it can be removed by means of tapping.

    Abstract: For the protection of an in-the-ear hearing aid against contamination by ear wax through the acoustic outlet port (34a) or a vent, a replaceable ear wax guard (36) is inserted in the aid and includes an essentially tubular element with a through-going cavity and an abutment collar in one end for sealing abutment against the hearing aid housing (31). For an easy and safe insertion and removal of the ear wax guard (36), an applicator is used, which in one end has a smooth pin for introduction in the through-going cavity of the ear wax guard (36) and in the other end a harpoon-shaped catch member. For mounting of the ear wax guard (36) a hose or tube member serving as acoustic outlet canal (34) is connected to an abutment collar (33) in abutment with the outside of hearing aid. The abutment collar is designed with oversize standard dimensions and adapted to an individually user-adapted hearing aid housing by preparation of its periphery edge.

  • Publication number: 20080298618
    Abstract: A cerumen protection system is to be held more securely in an earpiece of a hearing apparatus which can be worn in the ear. In particular, this is to be able to be ensured for the earpiece piece of an external receiver of a behind-the-ear hearing device. An earpiece with a sound exit opening and a cerumen protection facility which has an annular carrier and which is arranged in the sound exit opening, is provided, with the earpiece being manufactured from a rubbery-elastic material. A securing ring is also provided, which surrounds the sound exit opening, the inner diameter of which is smaller than the outer diameter of the carrier of the cerumen protection facility, which is less elastic than the earpiece and is fixedly integrated in the earpiece. The sound exit opening is thus reinforced so that the cerumen protection facility is not able to slide out thereof.

  • Publication number: 20080253597
    Abstract: A method and appertaining system provide for automatically adding a wax guard to a hearing aid shell impression. The location of a canal, tip of the canal, and central line of the impression are automatically identified in a digital 3D representation of a hearing aid shell impression. A first wax guard plane is determined at a predefined flip distance from the canal tip along the central line, and a second wax guard plane is determined at a predefined canal tip offset distance from the canal tip along the central line. A size and position for a feature of the wax guard is calculated based on predefined parameters, and the wax guard is constructed utilizing the calculated side and position. The type of wax guard can be a bell bore design, an open design, a Philip design, or a flip design.

  • Patent number: 7313245
    Abstract: An acoustically permeative intracanal cap is adapted to be worn semi-permanently deep in the ear canal for shielding a hearing device positioned deeper within the ear canal against moisture and debris infiltration. The intracanal cap conforms circumferentially to the walls of the ear canal for occlusion thereof, and comprises a porous membrane with pores sized to prevent water and solid debris from entering the ear canal while allowing air-conducted sounds to freely reach the microphone of the shielded hearing device. The intracanal cap may be entirely separate from the hearing device for independent insertion and removal, or attached to a lateral section of the hearing device for concurrent insertion and removal therewith into and from the ear canal.

    Abstract: With a hearing aid device barometric pressure equalization is intended to be achieved in a simple and economical manner in a sound canal between an earpiece and a cerumen protection system with a gas-tight membrane. To this end a pressure equalization canal is proposed, which opens into the sound canal. The pressure equalization canal preferably connects the sound canal to a vent. It can be produced in a simple manner when manufacturing the housing of the hearing aid device using a computer-aided manufacturing method.

  • Patent number: 7215789
    Abstract: A disposable hearing device is adapted to be positioned entirely within an ear canal for extended wear therein. The device includes a core assembly and a sealing retainer. The core assembly includes a lateral section of generally oval cross-section and generally elongated cylindrical shape for alignment substantially along the ear canal's longitudinal axis, and a receiver section having a receiver coupled to the lateral section for medial positioning in the ear canal's bony region. The lateral section includes a microphone and a battery assembly, and is dimensioned to avoid occluding the ear canal while it is at least partially laterally suspended therein. The sealing retainer is concentrically positioned over the receiver section, and has a composition to conform to the ear canal's bony region wall to seat the hearing device and acoustically seal it in the ear canal to inhibit feedback therein.
