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 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

The special Masking AssistantTMfeature 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.

TM

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

1 Introduction to MADSEN Xeta

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

The indicators are located on either side of the display. They light up when the selected test signal is presented
in the corresponding ear.

• Discreet mode
In the Auto Threshold and Auto Screening tests you can change the setting of the signal indicators to Dis-

creet mode, which means that they do not light up when the test signal is presented. If MADSEN Xeta is in

view of the patient, this will prevent the patient from knowing when a signal is presented.

This mode also prevents the patient from simulating hearing, because the stimulus level is hidden during
the automatic test.

3.2.6 Extended Range

Enables presentation of stimuli above the safety limit (approx. 100dB). The safety limit is set to 20dB
below the maximum dBHL for a given transducer and frequency.

If you select a different function when you have selected a user-defined test, the Settingbutton will flash to indicate the
change.

• To return to your original setting, press the Setting button briefly.

• To add this new function to your setup, press and hold the Setting button until you hear a beep.

Using a user-defined test

1. Press Setting1 (or Setting2) .

2. You can now perform a test based on the settings selected in Setting1 (or Setting2) .

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. Set-
tings 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.

3.2.10 Change Ear (L <--> R)

• Press this button to switch between testing the left and right ear.

3.2.11 Store/toggle threshold status

Stores a threshold in the internal memory. Thresholds are stored indefinitely (even if the power is switched
off), unless you delete them by pressing Clear.

If a previously stored threshold is present, it will be replaced by the new threshold when you press Store.

Toggle threshold status and symbol

• If you press and hold Store, it toggles the threshold status and symbol shown on the display between “threshold
value”, “No response” or no symbol. Release the button when it shows the wanted status.

Change frequency after Store

• You can set up the Store button to automatically change the stimulus to the next test frequency.

See AC store: Change freq. ► 59.

When you select a frequency and intensity at which a threshold value has previously been found, this value is shown in the
display by means of an "*" symbol beside the frequency indication, and the applicable audiogram symbol beside the level
indication, depending on the selection of ear, masking and transducer type.
