    A virtual audiometer was developed using the virtual instrumentation platform Labview7.1. VirtualEar is a system that permits the evaluation of the audible capacity of a person, through an audiometric prove by air, with masking, to detect the crossed audition. The audiometry is done producing pure tones in the audible frequency’s range (125Hz-8000Hz) with pressure intensity that varies in a range from 0dB to 100dB. Masking consists on sending a white noise signal to the opposite ear of the one that is being tested. Both signals are emitted through two separate channels, and in that way, the threshold of minimum audible pressure is detected. VirtualEar also permits to generate and save the information in tables, graphics and reports. Furthermore, it’s possible to control each patient’s files and print the results.
