The AudiSee system takes advantage of the factthat combined audio and visual cues provide at least 30% more informationto students than audio cues alone.This guide is written for users. It explains how to operate AudiSee’s differentmodules. Some sections have been written specifically for audiologists.The system is simple. The teacher wears a headset equipped with a cameraand microphone. The image is displayed via wireless transmission on asmall monitor on the student’s desk, on a larger monitor in front of the class,or on a computer screen. Sound is transmitted directly to the student’s FMsystem.The AudiSee system benefits both student and teacher.AudiSoft TM Technologies’ system can also be used in conferences, again providing many benefits for both speaker and participant.The following table presents the different components required for yourpreferred configuration.
