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 AssistantTM
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 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
Otometrics - MADSEN Xeta 7

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.
1.2 Intended use
MADSEN Xeta and the Audiometry module
Users: audiologists, ENTs and other health care professionals in testing the hearing of their patients.
Use: screening and diagnostic audiometric testing.
1.3 About this manual
Installation
See Unpacking and installing ►83 and Overview of MADSEN Xeta ►15 for a full description of unpacking instructions,
controls and socket connections.
Safety
This manual contains information and warnings which must be followed to ensure the safe performance of MADSEN Xeta.
Warning •Local government rules and regulations, if applicable, should be followed at all times.
•Standards and safety ►91
gives you an overview of device labelling and standards.
•Warning notes ►92
contains relevant warning notes.
Training
It is recommended that you read this manual and the OTOsuiteUser Guide, and make yourself familiar with MADSEN Xeta
before you begin testing a patient.
Note •If you are using the OTOsuite Audiometry Module with NOAH, we recommend that you are familiar with the
screens and functions provided in NOAH.
Terminology
The correct term for the person being tested/evaluated/serviced may depend on the setting in which the system is being
used. For this manual the term “Patient” was chosen, but you may configure OTOsuite to use another term.

2 Getting started
1. If you are using OTOsuite, install OTOsuite from the OTOsuite installation disk. See the OTOsuiteInstallation Manual.
2. Install MADSEN Xeta as described in Unpacking and installing ►83.
3. Connect the accessories, Installation ►83:
Socket connections - rear panel ►24 shows the location of the sockets for the various accessories required.
4. Customize your test setup and prepare the test equipment:
–User-defined tests ►14
–Preparing for testing ►45
5. Switch on MADSEN Xeta. MADSEN Xeta is ready for testing as soon as it is switched on.
6. Launch the OTOsuite Audiometry Module, if required.
7. MADSEN Xeta automatically starts in manual test mode. A new patient record is automatically available and is shown
briefly on the display.
Patients scheduled in the OTOsuite Audiometry Module and not yet tested are indicated by an empty set of par-
entheses: ().
See Patient data ►11 for patient handling.
8. You are ready to start testing.
–Manual air conduction testing
To perform manual air conduction testing, see Air Conduction threshold test (manual) ►67.
–Bone conduction testing
To perform bone conduction testing, see Bone Conduction threshold test (manual) ►70.
–Special tests
To select other tests such as
SISI, see SISI (Short Increment Sensitivity Index) ►74,
Stenger, see The Stenger test ►77,
Fowler (ABLB), see ABLB (Alternate Binaural Loudness Balance) ►76.
Press the function key below the test you wish to perform.
These tests are optional. To add any of these tests to your configuration, contact your local supplier.
9. To perform automatic testing, press:
–Auto Threshold for Automatic Threshold testing (Automatic Air Conduction testing ►12).
