Introduction
Version 2 Admittance (Y), and its components, Susceptance (B) and Conductance (G), may
be measured with probe tone frequencies of 226, 678, and 1000 Hz. The extensive
battery of test mode choices include the following:
• Diagnostic Tympanometry
• Acoustic Reflex Threshold and Decay Measurements
• Eustachian-Tube Function Testing (both intact and perforated eardrums)
• Screening Tympanometry/Reflex (automatic only)
• Acoustic Reflex Latency Testing
• Acoustic Reflex Sensitization
• Multiple Frequency Tympanometry (250 Hz to 2000 Hz)
The tympanometric measurement results are automatically scaled and presented
in equivalent ml of compliance at “Y”, 226 Hz. All “B” and “G” measure-
ments and measurements performed at probe tone frequencies of 678 Hz and
1000 Hz are expressed in mmhos. Sensitivity scales for the display of reflex
measurement results can be selected manually. Reflex test stimuli can be in-
put from an external source and presented via external control. A cursor is
available in all test modes for calling out numeric positions on the X and Y
axes.
Version 2 equipment TympStar options that can be connected to the rear panel include an external
connections and stimulus source, an external Present control, RS232 serial communication, a
options keyboard for entering patient information and a VGA monitor for displaying
test results. Other options offered for the TympStar for managing and archiving
data, include the following:
• Internal memory for storing up to 26 test results
• Data export to an external PC via RS232 serial interface
