Micro Audiometric Earscan ESTRAM The Earscan Acoustic Impedance Pure Tone Audiometer. This unit can be purchased with tympanometry only or with optional ipsilateral acoustic reflex, manual audiometry and automatic audiometry. Options not originally purchased can be added later as requirements change. The unit is designed to be easy to operate and to provide quick, accurate, and repeatable results. The serial port allows test data to be transmitted to an optional printer for single or multiple hard-copy reports, or to a computer for data management with commercially-available software. The impedance function can be used in either the standard 3- second sweep rate, or can be changed to the fast 1-second rate for testing infants or difficult patients.
