ABSTRACT:
The present invention relates generally to devices that monitor the condition within an ear, and more specifically to devices that are external to the ear and monitor the condition within the ear using a probe placed within the ear canal. The device comprises a signal generator for forming an electrical signal based on a condition within an ear, and an output for making the electrical signal accessible to an audio transducer. For example, in DPOAE testing, the signal generator is a microphone that forms an electrical signal from any otoacoustic emissions within the ear, any test signal within the ear, and any noise within the ear; and the output is an earphone jack for making the electrical signal accessible to an earphone worn by the operator. Thus, the operator can monitor any extraneous noise within the ear canal and monitor the progress of the test while the test is being performed.
