Measurement on ECHOSOFT
6.3 Hydrops (Shift-OAE and DPMC)
The scale of the phase graph is within ±180, but the measured value may exceed these limits. In this case, the points
have their phase reversed (±360°), appearing on the opposite edge of the graph. In most cases, this effect can be corrected
by centering the curve (see item 7). However, in cases where the phase shift between two extreme points exceeds 180°,
it is necessary to position the curve manually. By long-clicking on the "Phase" label you can drag the curve vertically.
4.
Adjust the size of dots displayed on the graphic in order to optimize the comfort of reading.
5.
automatically delete points below a certain signal / noise ratio, so that it does not disturb the interpretation of the
curve with inoperable points.
6.
Effect of the double mouse click on a point on the curve depending on the ticked box:
Point analysis
: Opens the Advanced point analysis window. See to section
Erreur ! Source du renvoi introu-
vable.
.
Delete a point
: removes a point on the graph (the point is only deleted during the display, at the next reload of the
curve, it will still be present). This allows for example to remove unacceptable points for which the signal to noise
ratio is not high enough.
7.
Selection of the studied phase shift (Only for the Shift-OAE): The established standards are related to the distortion
product 2F1-F2. However, it is possible to analyze the phase shift at 2F2-F1, F1-F2 and on the stimulation frequen-
cies F1 and F2. For some of these analyses, it is possible to apply a "corrected" mode which removes from the
distortion product the effect of the variation undergone by the stimulation frequencies.
Hide or show the signal/noise curve
Automatically put the phase shift curve in the middle of the graph to optimize the analysis. Show the values on the
graph (in order not to overload the graph if too much data is present).

9.
Provides a way of listing and saving the changes made to the curve (deletion of point and/or addition of an offset
to the curve).
10.
Displays or not the average values for each position. The "Calculate" button allows you to reset the averages if they
have been moved manually.

Print report options. There is also an option to export data as Excel file.
