Improved approaches are disclosed to update existing hearing devices by downloading software resources over a network from a remote server to a local client. The software resources are then stored in the existing hearing devices, thereby upgrading the functionality or operation of the existing hearing devices. Accordingly, existing hearing devices are able to be upgraded at convenient locations in a largely automated fashion. The invention is particularly useful for hearing aids or other sound systems for the hearing impaired.

A low-cost, four-channel cochlear stimulation system utilizes a completely passive, implantable receiver/electrode array that is inductively coupled to an external wearable processor. The receiver/electrode array is formed in a silicone rubber carrier adapted to be implanted in a deaf patient. At one end of the receiver/electrode array, positioned subcutaneously near the surface of skin above the ear, four receiving coils are arranged in an appropriate pattern. Such receiving coils are held within an hermetically-sealed titanium case. At the other end of the receiver/electrode array, which may be pre-formed in a spiral to match the basal turn of the cochlea, and which is inserted in the cochlea, four ball electrodes are spaced apart along an inner radius of the spiral. Each electrode is electrically connected to a respective receiving coil. Each receiving coil is also electrically connected to a reference electrode typically located near the receiver-coil end of the array.
