  • Page 9: Introduction To Madsen Zodiac

    MADSEN Zodiac is a compact device for immittance testing. MADSEN Zodiac is available both as a Quick Check device and as a diagnostic testing device. Both types can be operated either directly from the device (Stand-alone), and/or from the OTOsuite Immittance module software (PC-based).

  • Page 10: The Otosuite Immittance Module

    Printing test results Some versions of MADSEN Zodiac have a built-in thermal printer for printing test results. When MADSEN Zodiac is used in connection with the OTOsuite Immittance software module, test results can be transferred to OTOsuite for printing as OTOsuite reports.

  • Page 11: Intended Use

    Intended use MADSEN Zodiac is an auditory impedance tester that is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear.

    App. 5    MADSEN Zodiac Immittance Méthodologie et caractéristiques En raison de la physiologie des jonctions de neurones considérés, il est possible de provoquer un réflexe acoustique grâce à une stimulation soit de l'oreille ipsilatérale (oreille testée), soit de l'oreille contralatérale. Ceci implique donc que le réflexe acoustique est un phénomène binaural.
