![]() ![]() The user can define which frequencies to include in reflex testing, and the unit offers the ability to save up to 3 test parameters This feature performs tympanometry and a reflex testing sequentially, eliminating the need to perform tympanometry and reflexes separately. The SETUP icon may be used to select/deselect test frequencies, set start and stop intensity levels (50-100 dB HL range), and increment levels (5 or 10 dB HL). during testing, the START button turns to a yellow STOP button the system automatically performs acoustic reflex testing for selected frequencies using established parameters.FAST option generates pressure variation rate constantly at the max speech throughout the entire test.Ħ: Start button: pressing this button starts the tympanometry procedure When performing tympanometry, this option distracts child by showing animations on the display during testing.Ģ: Single vs Three Sequence button: Single option (designated with 1) performs one tympanogram three sequence option (designated by 3) performs three tympanograms in sequence with ability for provider to select the one to be saved in database.ģ:Pressure Range button: default setting =200/-400 daPa other option is +100/-200 daPa.Ĥ: Probe Tone button: default 226 Hz other option is 1000 Hz.ĥ: Pressure Variation Rate button: AUTO introduces pressure at max speed and then reduces when approaching peak compliance (to improve definition). The display screen also features several touch buttons for changing various parameters as follows:ġ: Mode button (adult or children): icon above indicates "Children function". The right portion of the blue header will show "L" for "Left Ear". The display will now show a tympanogram graph with a BLUE highlighted box and a BLUE horizontal header. To change ears, touch the general area of the red highlighted box. Above the box is a RED horizontal header with the letter "R" in the far left hand side, indicating "Right Ear". The left portion of the screen shows an RED highlighted box. The tympanometry display screen is shows below. How do I change testing parameters for tympanometry? ![]() when testing is complete, the yellow STOP button turns back to a green START button.during testing, the START button turns to a yellow STOP button.The system defaults to the right ear in the adult test mode with a constant pressure speed throughout the test using a 226 Hz probe tone. ![]()
