Measurement on ECHOSOFT
6.1 Evoked potential modul (ABR, ECochG et VEMP)
6.1.4
Script mode
This measurement mode enables to fully define a protocol. You can pre-set measurements by adjusting the order of
the ears tested, the powers, or the type of stimulation. Protocols thus defined are saved and can be re-loaded at any time.
You can create as many protocols as you want. This mode is useful if you want to make "burst" threshold at different
stimulation frequencies.

Summary description of the selected protocol
8.
Starting and stopping the measurement sequence.
The "Next" button allows to move to the next line
of protocol during a measurement without having
reached the pre-set number of stimulations
When you want to create or edit a protocol, the following window appears. It allows you to set all the parameters
related to the stimulation.
•
Textbox to define the name of the protocol.
•
Zone 1
contains the general parameters of the measurement to add: the ear, the power of stimulation, the number of
stimuli and the stimulation rate (number of stimuli per second).
•
Two stimulation type are available
-The Clicks (
zone 2
) are brief sounds, covering a spectral domain ranging from 1
kHz
to 4
kHz
.
They are characterized only by their duration
Th.
-The Bursts (
zone 3
) are pure tones containing a specified number of alternations at a fre-
quency. To prevent the attack power of the stimulator to be too fast and to generate a clicking
sound type, it is necessary to cut the Burst into 3 parts. We therefore define a number of as-
cending alternations
Tm,
a number of plateau alternations
Th
and a number of descending al-
ternations
Td.
Zone 4
indicates the total duration of the Burst in ms:
Tt
.
•
Zone 5
contains buttons to add or delete a line in the script.
•
Zone 6
is a table in which each row represents an acquisition of the script.
