Chapter 5. The use of ECHOSOFT software
5.4 Configuration
5.4.2
Medical software
This section allows you to configure third party patient
management software to import audiometry curves.
A first drop-down menu allows you to select the soft-
ware used. Then you must define the location where the
ECH
O
SOFT
software must come and get the infor-
mation from the patient. Finally, you must define the
location where the
ECH
O
SOFT
software must come to
deposit the results once the measure is complete, so that
the third party software can retrieve the curves.
5.4.3
Audiometry
This section allows the selection of active frequencies for pure-tone audiometry and automatic mode settings
1.
Selection of
active frequencies for pure-tone audiometry
.

The automatic threshold measure mode searches for a patient's hearing threshold over the frequency
range selected in
1
. The frequencies are scanned from 1000Hz to the highest frequency, then from 1000Hz to the
lowest frequency. Repeating the test at 1000Hz depends on the selection of the
"double validation at 1000Hz"
box. For each frequency, the test starts at the selected
"starting power".
The automatic algorithm performs the
power changes according to the rising threshold method, respecting the "
maximum power"
and
"minimum
power"
settings. The
"Response Timeout" is
the time limit after stimulus presentation during which the patient's
response is considered valid. The intervals between two stimuli are randomly modified according to
the maximum
and minimum interval
settings.
3.
The changes must be validated by pressing the
"Save"
button.
The maximum frequency for
AUDIOSCHOOL
devices is limited to 8000Hz
