Introduction to MADSEN Xeta MADSEN Xeta is an audiometer for testing a person's hearing. MADSEN Xeta offers air and bone audiometry as well as masking. Besides manual testing, MADSEN Xeta employs fast automatic screening and threshold audiometry algorithms. MADSEN Xeta incorporates multi-patient data storage and patient testing according to a preloaded patient list. •
MADSEN Xeta can be used in connection with the OTOsuite Audiometry Module software for online monitoring of test results, data export and storage, printing, and NOAH compatibility. Test intensities and frequencies as well as the current test settings and other information are shown on the PC monitor. A patient list can be edited in the software and downloaded to MADSEN Xeta.
Operation The front panel buttons have indicator lights, which clearly show the device's current settings. Sound level, frequency and other information are shown clearly on the device display. You can download new firmware to MADSEN Xeta, and if this involves no change to the transducers, MADSEN Xeta does not need to be recalibrated.
1.1
The OTOsuite Audiometry Module The OTOsuite Audiometry Module software provides a comprehensive overview of the current stimulus and masking choices both numerically and graphically in the displayed audiogram(s) while testing with a connected Otometrics audiometer. As the module is part of OTOsuite, audiograms can be used directly in other OTOsuite modules such as AURICAL Counseling and Simulations for an optimized workflow independent of NOAH. The OTOsuite Audiometry Module lets you work with NOAH or save and view results via XML files. The current version supports • basic tone audiometry and •
speech testing
•
special tests, depending on the audiometer being used.
Masking Assistant TM The special Masking AssistantTM feature will notify you of thresholds that you might consider checking again with masking applied. You may use this feature not only during testing but also to pinpoint possible masking issues with previously recorded audiograms. The applied masking rules match the general recommendations in the audiometry literature.
Over the rim testing Testing with the audiometer connected to a PC allows you to use the audiometer primarily as a handy control panel while you follow the actual stimulus settings and test progress on your standard PC display. The large stimulus and patient response graphics at the top of the display gives you a clear overview while keeping your focus on the patient.

1 Introduction to MADSEN Xeta
Patient test planning The OTOsuite Audiometry Module supports planning of patients for safe offline testing in the field. You can create a list of patients which can then be downloaded to the audiometer. Each planned patient can now be safely identified, selected and tested with the audiometer based on name and personal identification. The results can be bulk uploaded to the PC later on. For specific information regarding audiometric test procedures and settings, please see the documentation for the specific audiometer.

Automatic reload of the last used settings MADSEN Xeta is optimized for testing patient after patient in the same consistent manner. To support this, MADSEN Xeta remembers the settings you used for testing the previous patient, i.e. the settings selected when the first threshold was stored. If Setting 1 or Setting 2 was used, that setting will automatically be reloaded and used for the next patient. Settings are reloaded whenever you select New Patient, change patient using the right or left arrows, and when you switch the power off and back on. MADSEN Xeta has a third configurable setting. If neither Setting 1 or Setting 2 is selected (you can de-select Setting 1 or Setting 2 by pressing the active Setting button twice) the audiometer uses the third setting. The third setting is defined as the settings present when storing the first threshold for a patient while neither Setting 1 or Setting 2 were selected. The third setting is also remembered and reloaded from patient to patient.
