Abstract

A hearing aid programming system with a host computer system including a program for programming a hearing aid. The host computer system includes a first communication interface for sending and receiving control and data signals. A hearing aid programming interface device is connected to the communication interface of the host computer system and includes a second communication interface for sending and receiving control and data signals. The hearing aid programming interface device also includes circuitry for electrically isolating the hearing aid to be programmed from the host computer. The first communication interface may be PCMCIA, USB, RS-232, SCSI or IEEE 1394 interfaces, which are arranged to send and receive serial data and control signals to the hearing aid programming interface device. The first communication interface may also be a wireless communications interface which wirelessly sends and receives control and data signals with the hearing aid programming interface device.
