Tone Decay
The Tone Decay test evaluates auditory fatigue. The general procedure is to
measure the ability to perceive and maintain a pure tone presented continuously
(usually for 1 minute).
The top section of the display has the common elements found on the previously
described screens. The center section displays the timer. The timer is started
when the patient presses the response button or may be started manually from the
Correct/Start button on front panel. When the patient response button is released
it pauses the timer and when pressed again resumes. The Navigation Menu has
an option for the dB Step and an option to set the time in minutes (1-4). The time
setting in the Navigation Menu will stop the timer after the defined number of
minutes is reached on the timer. The results are not transferred to GSI Suite via
the data transfer and therefore should be entered as a comment.
