Abstract

A method and apparatus for operation of a hearing aid 205 with signal processing functions performed with an array processor 220. In one embodiment, a reconfiguration module 250 allows reconfiguration of the processors 220 in the field. Another embodiment provides wireless communication by use of earpieces 105, 110 provided with antennas 235 in communication with a user module 260. The method includes steps of converting analog data into digital data 915 filtering out noise 920 and processing the digital data in parallel 925 compensating for the user'"'"'s hearing deficiencies and convert the digital data back into analog. Another embodiment adds the additional step of reconfiguring the processor in the field 1145. Yet another embodiment adds wireless communication 1040-1065.
