All test modes allow the user to individually program a unique set of default
test parameters. User-programmed parameters override GSI-developed de-
fault parameters.
The TympStar Version 1 measures compliance using a 226 Hz probe tone.
The following probe tone frequencies are available:
• 226 Hz - All Tests
• 678 Hz - Tymp Diagnostic, Reflex Threshold, Reflex Decay, ETF
• 1000 Hz - Tymp Diagnostic, Reflex Threshold, ETF
• 250 Hz - 2000 Hz Sweep - Multiple Frequency Tympanometry
The TympStar Version 1 measures compliance, and shows the tracing on the
graphic display as a solid line.
The TympStar Version 2 measures admittance (Y), and its components:
Susceptance (B) and Conductance (G). Admittance (Y) and Susceptance (B)
tracings are solid lines, while tracings of conductance (G) values are dotted
lines.
