Abstract: The present invention relates to recipient fitting of a hearing device. An embodiment of the present invention determines the transmission loss for sound applied to the recipient by the hearing device. Separate gains are then determined for compensating for the determined transmission loss and the measured hearing loss of the recipient. For example, in an embodiment, the hearing device may compensate for transmission losses in a 1:1 manner (i.e., the transmission loss in 100% compensated for). The hearing device may apply a different gain to compensate for the hearing loss, such as a gain that is a fraction (e.g., 33-55%) of the measured hearing loss.
Abstract: A method for pre-processing a channelized music signal to improve perception and appreciation for a hearing prosthesis recipient. In one example, the channelized music signal is a stereo input signal. A device, such as a handheld device, hearing prosthesis, or audio cable, for example, applies a mask to a stereo input signal to extract a center-mixed component from the stereo signal and outputs an output signal comprised of a weighted combination of the extracted center-mixed component and a residual signal comprising a non-extracted part of the stereo input signal. The center-mixed component may contain components, such as leading vocals and/or drums, preferred by hearing prosthesis recipients relative to other components, such as backing vocals or other instruments.
Abstract: A bone conduction device configured to couple to an abutment of an anchor system anchored to a recipient's skull. The bone conduction device includes a vibrating electromagnetic actuator configured to vibrate in response to sound signals received by the bone conduction device, and a coupling apparatus configured to attach the bone conduction device to the abutment so as to impart to the recipient's skull vibrations generated by the vibrating electromagnetic actuator. The vibrating electromagnetic actuator includes a bobbin assembly and a counterweight assembly. Two axial air gaps are located between the bobbin assembly and the counterweight assembly and two radial air gaps are located between the bobbin assembly and the counterweight assembly. No substantial amount of the dynamic magnetic flux passes through the radial air gaps.
Abstract: Presented herein are trans-modiolar stimulation techniques in which stimulation current is sourced (delivered) by at least one intra-cochlear stimulating contact and is sunk at a group of other intra-cochlear stimulating contacts. The group of other intra-cochlear stimulating contacts is positioned (located) across a section of the recipient's modiolus from the intra-cochlear stimulating contact that sources the stimulation. As such, stimulation current generally passes through the modiolus to stimulate spiral ganglion cells and evoke a hearing percept.

Abstract: A device, system and method for inserting a pre-curved electrode array (100) held in a substantially straight configuration by a straightening member (101) into a cochlea of a subject. As the electrode array (100) is inserted into the cochlea by the device, the straightening member (101) is held by the device such that the electrode array (100) advances off the straightening member (101) such that it is free to take on its pre-curved configuration in the cochlea of the subject.

Abstract: Methods, systems, and devices for receiving a data signal and a power signal by a hearing prosthesis are disclosed. An input signal is received at a first unit of a hearing prosthesis. The first unit receives the input signal at a wired interface module that conforms to a standardized interface. The first unit identifies a data signal and a power signal included in the input signal. The first unit transfers at least a portion of the power signal to a second unit of the hearing prosthesis. The second unit is implanted in a body and is configured to stimulate an auditory organ, allowing a user to perceive at least a portion of a sound.

Abstract: Embodiments presented herein are generally directed to a protective sleeve for an external component of a hearing prosthesis. The protective sleeve comprises a base plug configured to be inserted into a main body. The main body and base plug are each primarily formed from a substantially flexible material and each comprises one or more substantially rigid members. When the base plug is inserted into the main body the substantially rigid members operate to deform a portion of substantially flexible material forming part of the main body or base plug to seal the base plug to the main body.
