PATIENT'S DETAILS
Before starting the test, press
will be displayed; enter their identification data (ID number, clinical history number, etc.), name and surname. If the ELI diagnosis
is selected, the patient's age and gender also need to be entered.
Optionally, the automatic Identifier mode can also be activated. The audiometer will automatically assign a sequential number to
the new patient (preceded by the # symbol in the identifier), so the patient´s name and surname will not need to be entered.
When this mode is activated, pressing
and the patient's data editing screen does not come up.
A previously-saved patient can also be selected from the database by pressing
At any time during the test, patient data can be accessed by pressing the patient's identifier box (b) on the top bar of the screen.
Note: When creating a new patient, if there is an ongoing test with unsaved values, a warning message displays, so that these can
be saved before starting a new test.
SETTING A HEARING THRESHOLD
To set the hearing threshold at a certain frequency, follow these steps:
•
Select the frequency that you want to examine by turning the Frequency Setting (C). Normally, this starts at the 1000 Hz
frequency.
•
Select the signal level you want to apply by turning the Intensity Setting (B). You can start with a level which is clearly audible
for healthy people, for example, 40 dB.
•
Apply a continuous tone for 1 or 2 seconds, pressing the Signal Application button (D).
•
When the patient presses their Response Button, the main screen background will turn green.
•
If the patient responds before the signal is applied, or more than 2 seconds after it is applied, the screen background will turn
red, indicating that the patient's response is not coherent. Apply the tone again until you obtain a coherent response, or give
the patient instructions again.
•
If the patient gives a correct response, reduce the intensity by 10 dB and reapply the tone.
•
Continue decreasing intensity in 10 dB steps and applying tones until there is no response from the patient.
•
If the patient does not respond, increase intensity in 5 dB steps, until they respond.
•
Every time the patient produces a response, decrease the intensity by 10 dB, and every time there is no response, increase
it by 5 dB.
•
The time interval between tones must be varied randomly, so that the patient does not predict when the tone is going to be
applied. The interval between two tones must always be longer than their duration.
