ABSTRACT:
A hand held ear test probe is disclosed for use in clinical evaluations of hearing problems. There are a number of important tests for evaluating hearing system losses which are based upon measurements taken in patients' external ear canals using a test probe. A probe is described for such tests which is inserted in the patient's ear and which is hand held by the clinician without the use of head bands or other probe supports. The hand held probe has a shaped outer casing which supports the probe and the related ear sealing and pressurizing means as well as the transducers for the transmitted and received audio test signals.
