Abstract

A method and apparatus for performing various auditory tests utilizing a hand-held, portable, wireless testing device is provided. Within the device is a diagnostic subsystem used to implement and analyze selected tests. Attached to the device, either directly or via a flexible cable, are one or more probes. A processor, storage means, input means and display means are included, thus allowing the device to process and store instructions as well as process, store and display data. A wireless networking subsystem is included, enabling the device to communicate with other, similarly enabled, systems and devices within the device'"'"'s communication range. Due to the inclusion of the wireless networking subsystem, the device can be configured to allow the user to transmit and/or print data, connect to a network, obtain device configuration updates, and send and receive patient and office updates.
