Measurement
Click to select the condition you wish to apply to the audiogram.
SDT • The data will be stored as a S peech D etection T hreshold. This is the lowest level at
which the patient responds to speech at least 50% of the time (also known as SAT - Speech
Awareness Threshold).
SRT • The data will be stored as a S peech R eception T hreshold. This is the lowest level at
which the patient repeats at least 50% of spondaic words correctly.
MCL • The data will be stored as a M ost C omfortable L oudness level. This is the level at which
the patient reports it is most comfortable to listen to the speech stimulus.
UCL • The data will be stored as an U n C omfortable L oudness level. This is the level at which
the patient reports that the speech stimulus is uncomfortably loud.
WRS/SRS • The data will be stored as a W ord R ecognition S core or S entence R ecognition S core.
This test requires monosyllabic words to be presented at the patient's MCL level or above.
The patient is instructed to repeat the words he or she hears.
SNR/dB step
•
S
ignal to
N
oise
R
atio in dB step.
If you check SNR , you can report a S ignal to N oise R atio in the speech result descrip-
tion box. This also stores the speech data as a "speech in noise" test and is accordingly dif-
ferentiated from a regular speech measurement.
IPSI routing
IPSI
• Click to select the IPSI routing. IPSI routes the non-stimulus channel to the same ear as the
speech stimulus. That way, a speech in noise test can readily be administered.
Masking/Stimulus 2
On
• Click
Masking/Stimulus 2 On
to enable non-stimulus channel presentation.
This selection depends on the Input selection for the non-stimulus channel.
