A hearing aid shell fixture is formed that comprises an interior region identical in shape and size to an interior region of an actual hearing aid shell, and a replica of one or more shell components that is positioned so as to replicate a position and size of one or more real shell components in the actual hearing aid shell. The hearing aid shell fixture is placed onto a faceplate assembly that comprises a floating component, and a position of the floating component is adjusted to avoid contact with the replica of one or more shell components. The hearing aid shell fixture on the faceplate is subsequently replaced with the actual hearing aid shell. | 03-05-2009 |
20090063107 | Manufacturing Process of Hearing Aid Shells With Reduced Surface Distortions and Adaptive Shell Surface Modification to Improve Fit and Appertaining System - A method and appertaining system is provided for reducing distortions in a hearing aid shell having complex surfaces with areas having high and low curvatures, the distortions occurring due to uneven material loss during tumbling and buffing operations. The method determines the curvature in defined regions of the shell and determines a new shell surface that is dependent upon the curvature in each respective region. Templates may be utilized th further define the new surface. With the new surface thus defined, the tumbling and buffing operations result in an end product having the desired shape. | 03-05-2009 |
20090067656 | Protective Finishing Plug For A Hearing Instrument Shell - During tumbling, a plug may be inserted into the opening of a hearing instrument shell to protect the hole and minimize additional cleaning operations subsequent to tumbling. A suitable conforming plug may be fabricated at the same time the shell is made. | 03-12-2009 |
20090123015 | Composite Receiver Tube For A Hearing Instrument - The compliance of a receiver tube for a hearing instrument may be enhanced by fabricating it as a composite assembly of a tube and a compliant insulator positioned between the tube and the receiver. The material of the insulator is selected such that it has a greater compliance than that of the tube. | 05-14-2009 |
20090196447 | Assembly Method of Custom Hearing Aids - The present invention relates generally to a method for assembling a hearing aid device, comprised of providing a software system that determines a position for a virtual receiver and a position for at least one component of a virtual faceplate inside a hearing aid shell. The present invention also includes utilizing guides to replicate the position for the receiver and the position for at least one component of the faceplate during construction of the shell, and providing the software system to verify that the receiver and one or more components will not collide with the faceplate and guides. The present invention is further comprised of providing the software system to merge the shell with the guides. | 08-06-2009 |
20090238388 | Hearing Aid With Enhanced Vent - A hearing aid with a microphone for receiving acoustic signals and converting them to electrical signals, electronic circuitry for processing the electrical signals, and a speaker for converting the processed electrical signals into acoustic signals, has a shell that encases at least portions of the microphone, the electronic circuitry, and the speaker, the shell further encasing an inside volume. The hearing aid further has a vent that provides an opening between the inside volume and a region external to the hearing aid. A flexible membrane is provided that covers an opening of the vent and an acoustic resistor that contacts the flexible membrane. The membrane helps prevent wax fumes from entering the inside volume, and the acoustic resistor helps to reduce distortion in the frequency response of the hearing aid. | 09-24-2009 |
20090285427 | Receiver Tube and Retaining Clamp Assembly for a Hearing Instrument Receiver - A receiver tube for a hearing instrument may be securely affixed to the instruments receiver with a retaining clamp. Such an arrangement facilitates assembly and repair, and provides a positive means for the securing the receiver tube. | 11-19-2009 |
20090296971 | Hearing Instrument Receiver With Improved Low-Frequency Efficiency - The low frequency efficiency of a hearing instrument receiver can be improved by increasing the unoccupied rear volume. The receiver may be configured with one or more motor and diaphragm assemblies. The receiver may also be fabricated using multiple, conventional receivers with an added housing to create the increased, unoccupied rear volume. | 12-03-2009 |
20100092001 | COUPLER FOR OPEN FITTING HEARING AID MEASUREMENTS - In a system and method for open fitting hearing aid frequency response sound measurements, a test space is provided having located therein a sound source, a hearing aid with a microphone, and an open fit receiver. An acoustic shield is provided and within the acoustic shield an ear simulator coupler is provided having an ear extension attached thereto, the ear extension having mounted thereto at least a portion of the open fit receiver. A measurement unit receives sound signals from the ear simulator coupler. | 04-15-2010 |

20120008808 | HEARING AID WITH OCCLUSION REDUCTION - A hearing aid having hearing loss-compensating components, active occlusion reduction components, a vent, a tuned piston, and a flexible surround. The piston and the surround combination are assembled on the faceplate and cover the outside end of the vent that is situated on the faceplate. The piston and the surround combination minimize the adverse effects of walk-induced head vibrations. | 01-12-2012 |
20140161267 | Method for Determining the Sound Pressure Level at the Eardrum of an Occluded Ear - The sound pressure level at the eardrum may be determined by constructing an optimized model of the ear canal and then calculating the simulated sound pressure level at the eardrum. The model is obtained by comparing real-ear-to-coupler differences between the sound pressure level measured at a fixed distance from a hearing instrument and a simulation of the measurement, optimizing the model by varying the length and/or diameter of the canal model, repeating the simulation and determination of simulated real-ear-to-coupler difference until the differences between the measured and simulated values are minimized. The optimized real-ear-to-coupler difference at the eardrum may then be determined and in turn the sound pressure level at the eardrum may be calculated. The sound pressure level at the eardrum may then be used to acoustically fit the hearing instrument to the person. | 06-12-2014 |
20140251716 | Conformable Dome Ear Canal Tip for a Hearing Instrument - An ear canal tip for a hearing instrument comprises a series of slits in the ear canal tip surface to allow the ear canal tip to conform to the shape of the ear canal when the ear canal tip is inserted into the ear canal. | 09-11-2014 |
