  • Patent number: 7876918
    Abstract: For reducing wind noise effects in a hearing instrument, a converted acoustic signal is processed in a number of frequency bands, a low frequency band of which is chosen to be a master band. A wind noise attenuation value is determined in each frequency band, based on a signal level in the frequency band concerned and on a signal level in the master band. A further wind noise reducing effect may be achieved in hearing instruments with at least two microphones where in the presence of wind noise the instrument may be switched from a directional mode to a omnidirectional mode in which an average of the output signals of the two microphones is used as signal. In single microphone hearing instruments, the microphone signal and a delayed version of this signal are used to improve wind noise detection and reduction.

  • Patent number: 7444877
    Abstract: A directionally-sensitive device for detecting and processing vibration waves includes an array of polymeric optical waveguide resonators positioned between a light source, such as an LED array, and a light detector, such as a photodiode array. The resonators which are preferably oriented substantially perpendicularly with respect to incoming vibration waves, vibrate when a wave is detected, thus modulating light signals that are transmitted between the light source and the light detector. The light detector converts the modulated light into electrical signals which, in a preferred embodiment, are used to drive either the speaker of a hearing aid or the electrode array of a cochlear implant. The device is manufactured using a combination of traditional semiconductor processes and polymer microfabrication techniques.

  • Patent number: 7369670
    Abstract: The invention relates to an active hearing protection earplug comprising a shell (2000) to be worn at least in part in a user's ear canal and being adapted to attenuate sound waves arriving at the outer end (2001) of the shell, and an active system (2002, 2010) comprising an input transducer (2024) for converting ambient sound into audio signals, an audio signal processing unit (2028) for processing said audio signals, and an output transducer unit (2010) mounted within the shell for converting said processed audio signals into sound output at the inner end of the shell, wherein the amplification of the active system is negative and wherein the output transducer unit comprises at least two separate outputs (2032, 2034). The invention also relates to a method for manufacturing such an earplug.

  • Publication number: 20080078082
    Abstract: A system and appertaining algorithm provide a cutting and shaping of the hearing aid shell using an Ellipsoidal Line Cut that increases the speed of detailing operations and enables a creation of more cosmetically appealing shells. A contour algorithm determines a projected contour on the bottom cut plane that corresponds in shape to a portion of the line cut plane contour, and a merger algorithm defines a line cut surface between the portion of the line cut plane contour and the projected contour. An elimination algorithm eliminates parts of the new hearing aid shell design that extend beyond boundaries defined by the original hearing aid shell design.

  • Patent number: 7286679
    Abstract: A system and method for modeling binaural shells for hearing aids, wherein the system is configured to load data associated with a first and a second ear shell. The system is further configured to register the data associated with the first and the second ear shells and process the first ear shell and the second ear shells, wherein the processing on the first ear shell is automatically performed on the second ear shell.

  • Patent number: 7024012
    Abstract: A modular hearing aid for arrangement in a user's ear comprises a hollow plug (1) adapted to the ear canal and having a generally irregular conical shape and an exterior opening which is covered by a faceplate (2), in which a recess (8) is formed for removable arrangement of a battery (23) as well as an electronic module (4) comprising a microphone part (5), a signal processing part (6) and a sound reproducer (7). The recess (8) comprises a first region (9) for insertion of the battery (23) and a second region (10) coherent with the first region for placing of a socket part (11) of the electronic module (4), and at the edge of the recess (8) the faceplate (2) is formed with engaging means (12–16) for the socket part (11), whereas further parts of the electronic module (4) are placed below the faceplate (2). The recess (8) is formed such that at removal of the battery (23) the first and second regions (9, 10) together allow passage also of said further parts (6,7) for removal of the complete electronic module.

  • Patent number: 6920414
    Abstract: The present invention relates to a CAD/CAM system for design and manufacture of a hearing aid housing comprising a face plate and a shell that is matched to the auditory canal of a user, the system being adapted to receive and process data representing the shape of the auditory canal, forming a three-dimensional model of the shell based on the data, and outputting data representing the model for production of the shell and the face plate based on the model. Manufacture of the face plate includes at least one automatic processing step based on data from a CAD/CAM model of the hearing aid housing. For example, data relating to the circumference of the face plate may be provided to a numerically controlled machine that automatically cuts a separately manufactured face plate along the desired contour that matches the circumference of the corresponding shell. In another embodiment, the hearing aid housing is manufactured with an integrated face plate.

  • Patent number: 6829362
    Abstract: A curable composition and method for producing a soft yet durable elastomeric in-the-ear product having a Shore A hardness of about 55 or less upon cure. The curable composition incorporated in a hearing aid apparatus provides a soft, flexible tip member which was mated to a rigid hearing aid shell. The tip member provides better comfort, durability and acoustic performance for a variety of ear canal shapes and movements. The curable composition which provides these properties includes a urethane acrylate oligomer and a reactive plasticizer or reactive diluent to provide a Shore hardness of about 55 or less upon cure. The curable composition may be used for other ear-worn products where these properties are desired like for ear plugs, ear phones and ear connectors.

  • Publication number: 20040168852
    Abstract: A linkage assembly (140) is used for mechanically coupling an armature (124) and a diaphragm (118) of a balanced receiver (100), the linkage assembly (140) formed from a first linkage member (822) displaced from a strip of stock material (800) relative to the plane of the stock material (800) and a second linkage member (826) displaced from the strip (800) relative to the plane. The first and second linkage members (822, 826) are then joined while secured to the strip (800). At least one severable connecting member (870a-c) securing the linkage member to the strip (800) is severed to release the linkage member from the strip for assembly of the linkage member into the receiver. A method of forming a three-dimensional structure from flat stock is used to form the linkage assembly (140).
