An improved hearing aid programming system with a host computer for providing
at least one hearing aid program and having at least one personal computer memory
card international association (PCMCIA) defined port in combination with a PCMCIA
card inserted in the port and arranged for interacting with the host computer for
controlling programming of a hearing aid. The host computer provides power and
ground to the PCMCIA card and provides for downloading the hearing aid programming
software to the PCMCIA card upon initialization. A microprocessor on the PCMCIA
card executes the programming software. A hearing aid interface for adjusting voltage
levels and impedance levels is adapted for coupling signals to the hearing aid
being programmed. A portable programming arrangement utilizes a portable multiprogram
unit to store one or more hearing aid programs, and having an electrical interconnection
to a portable multiprogram unit interface, whereby one or more programs selected
at the host computer can be downloaded and stored in the portable multiprogram
unit. The portable multiprogram unit includes a wireless interconnection for transmitting
selected ones of the programs to hearing aids to be programmed.
