Operating Instructions
DPOAEs in the range of 1.5 kHz to 12 kHz
TEOAEs in the range of 0.7 kHz to 4 kHz.
Tymp•OAE Probe™
The Tymp•OAE Probe allows for measurements of:
DPOAEs in the range of 1.5 kHz to 12 kHz
TEOAEs in the range of 0.7 kHz to 4 kHz
Tympanometry with a 226 Hz or 1000 Hz probe tone
Acoustic reflexes with 226 Hz probe tone (stimulus options: 0.5, 1, 2, & 4 kHz; broadband noise,
low pass noise & high pass noise) or 1000 Hz probe tone (stimulus options: broadband
noise)
The status indicator bar on the Tymp•OAE Probe will indicate the pressure sweep of the pump by
showing a sweeping sequence of lights.
Note: When idle (not testing) the probe status LED should be solid green. If the LED is yellow when idle
then the probe has not been detected by the instrument. Power off the instrument, check the probe
connection, and turn the instrument on again to detect the probe. The status LED should now be solid
green.
The external probes are preferred by most users when conducting OAE measurements for infants,
young children, and other difficult to test populations such as individuals with multiple handicaps. The
external probe allows the user to insert the probe tip into the ear and then wait until the patient is quiet
before starting the test. The internal probe may be preferred by some users for fast OAE testing of
cooperative patients.
Installing the External Probe
The external probe keypads consist of a left (indicated by
L
) and right (indicated by
test protocol or series. Below the left and right buttons
are blue (for left) and amber (for right) LEDs which
illuminate during testing to indicate the ear under test.
Each probe provides a status indictor in the form of LED(s)
located on the keypad. In the case of the OAE•Probe the
indicator is between the left and right buttons. On the
Tymp•OAE Probe the indicator is a row of LED's above
the left and right buttons.
The LED located between the left and right buttons
indicates status of the probe:
