1. Place the probe tip in the test ear.
2. Test 1000, 2000, and 4000 Hz
3. Present stimulus at 80 dB HL (100 dB HL = max limits of immittance bridge)
4. Use method similar to Hughson-Westlake
-If reflex is present, decrease by 10 dB HL
-If the reflex is absent, increase by 5 dB HL
5. Once you determine the threshold record results on the immittance form.
