A fast response impedance meter for acoustic reflex measurements.
The response time of the instrument is a crucial parameter for the measurement of accurate morphology and latency of the acoustic reflex. An improved impedance meter accounting for this particular problem was designed for the measurement of the contralateral acoustic reflex. The temporal characteristic of the measurement apparatus will be shown, as well as an example of an application in a normal hearing individual. The module can be incorporated into already existing instruments with some modifications.
