1 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 pre-
loaded 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 mon-
itor.
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 cur-
rent stimulus and masking choices both numerically and graphically in the displayed audi-
ogram(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 Coun-
seling 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 Assistant
TM
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 recor-
ded 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.
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
