Simulating reflex induced changes in the acoustic impedance of the ear.
A simple procedure for measuring changes in the acoustic impedance of the ear is described. The technique has several applications, including simulation using a standard coupler of changes in real ear impedance produced by the acoustic reflex. The technique has also been used for calibrating the response time of an otoadmittance meter used in measuring the temporal characteristic of reflex activity.
