Channel 1 and Channel 2 Windows
The sound wave icon and the VU meter indicate when a stimulus is being
presented. The sound wave icon and VU meter will remain active through the
duration of the stimulus.
The intensity of the stimulus will be displayed in the color of the ear that has
been selected for each channel (red for right, blue for left and black for binaural).
At extreme intensity levels, the intensity value will be highlighted in yellow.
When the attenuator has reached its upper limit (per transducer) the level will
flash and the NR symbol will appear.
The stimulus source (Microphone, INT/EXT A or INT/EXT B), ear selected, and
transducer selected are displayed at the bottom of the channel windows. The
signal type, ear and transducer may be selected with the mouse to display a drop
down list of choices for selection.
Scoring Window
This scoring window displays the speech scores in a percentage value. The scores
are populated using the Correct/Incorrect buttons on the front panel of the
instrument. The left side indicates the number of correct responses over the total
presented. The right side converts this into a percentage. The lower part
indicates the current word being presented.
NOTE:
When using internal .Wav files, the Correct, Incorrect and Clear
buttons are inactive while the stimulus is being presented.
On Screen Data Logging
Pure Tone Average (PTA) for air and bone conduction is automatically
populated from the tone test screen if the data is available. The audiologist may
quickly compare the results of the PTA with the results of the Speech Reception
Threshold (SRT) or Speech Detection Threshold (SDT) to rule out the possibility
of pseudohypoacousis.
Speech Intelligibility Index (SII) is automatically populated from the tone test
screen if the data is available. The audiologist may quickly quantify the speech
information that is audible to the patient and compare to the word recognition
score (WRS). There is a high correlation between SII and WRS.
Speech Test Results
The Speech Test Results Table displays the speech information for the tests that
have been stored. To store a speech test result the Store button is pressed on the
instrument. The results table stores the ear, test type speech source, the word list
presented, if an aid (hearing aid or cochlear implant) was used by the patient, the
percentage correct, the HL level and the masking level. There are two tables and
each table can hold up to 6 tests.
