USING THE OTOSURE
5.1.
EQUIPMENT PREPARATION
Connect the headset and the patient response switch to the Otosure and then make the connection from the
Otosure to the PC. No specific warm-up time is required although the device registration to the PC might
take a short time to complete.
5.2.
STARTING THE SOFTWARE
Start the Audibase application, and with reference to the user manual either establish a new a patient, or
access and display details of an existing patient.
Use the left mouse button to click on the Launch Test icon in the Audibase toolbar.
Alternatively use the “Test > Launch Test” drop-down menu selection at the top of the Audibase window.
A new window will open for the Otosure software. If the patient has more than one set of audiometric results
stored in Audibase the most recent audiogram is transferred and displayed in the Otosure window.
The serial number and calibration date of the connected Otosure audiometer is shown at the bottom right of
the Otosure window along with the test type currently selected.
The test type last used is remembered; if this was a manual test the procedures may be followed; if this was
an automatic test the following dialogue box will be displayed:
To run the same automatic test using the same options (as last used)
simply click the “Start test” button and the test will commence.
If a manual test is required, or if the test options are to be modified,
click the “Modify” button which will close the dialogue box.

AVAILABLE TEST MODES
5.3.1.
MANUAL TESTING
This allows the operator to use the Otosure to record hearing level thresholds using the
computer’s keyboard
and mouse. The resulting audiometric data may then be transferred to the Audibase application.
5.3.2.
COMPUTER TESTING
This is a method of automatic audiometry based on the Hughson and Westlake method and undertaken
automatically by the instrument. The level is increased in 5dB steps until a response is obtained from the
patient and decreased in 10 dB steps until no response occurs. The process is repeated until, depending
upon the criteria selected for recording a threshold, the instrument will record a threshold at that particular
frequency. The Otosure then continues to the next test frequency and so on to complete the test on both
ears.
