Computer Audiometer for Hearing Testing

In this paper, we present a prototype of a simple audiometer CAUM (Computer AUdioMeter) based on a computer equipped with a standard sound card. It is a software developed under windows in order to provide a virtual instrument of a standard audiometer on computer. It has functionality to test a patient's hearing using pure tone testing and white noise masking signal. The functions and performances of the prototype are evaluated by hearing tests and compared with classical AC50 audiometer.
