102 Hearing Aid Measurements WinCHAP User’s Manual
7.4.3 Sending a target to your analyzer
Instead of manually generating a target on your analyzer, you can send the tar-
get to your analyzer from WinCHAP.
See Section 5.5.1 for instructions on generating an insertion gain target from
WinCHAP and sending it to the analyzer. See Section 5.5.2 for instructions on
sending an audiogram to the analyzer.
7.4.4 Sending curves to your analyzer
You can send any curve displayed in the Real-Ear window to your analyzer
using the Send Curves button.
1. Choose the curves you want to send to your analyzer by having them dis
-
played on the window. You can send up to four curves. If you have more
than four curves displayed, only the first four will be sent.
2. Click Send Curves
. This will open a new window.
3. Select Probe
.
4. Select the desired ear.
5. Click
Go to send the curves. A window will open, confirming that the
curves have been sent.
6. Click
Back to close the Send Curves window.
7.4.5 Adding Curves & Deleting Curves
The Real-Ear window has many similarities to the Response Curves window.
Like the Response Curves window, you can add saved curves to the graph, you
can delete curves from the graph, and you can create custom labels for the dis
-
played curves.
To do these things, see the explanations in Section 7.3.5, Section 7.3.6, and
Section 7.3.7, respectively.
7.5 Automated Test Sequences
There are six different automated test sequences that you can store in WinCHAP
after you’ve run them on your analyzer. Figure 7.5 shows an example of the
ANSI 87 automated test sequence screen.
• The ANSI 87 sequence runs a complete test of the hearing aid in accor
-
dance with the ANSI S3.22-1987 requirements.
• The ANSI 92 is an automated test sequence the uses a noise signal to give
you a family of curves and is according to ANSI S3.42-1992.
• The ANSI 96 sequence is a revision of the ANSI 87 sequence and is
designed to more thoroughly test AGC aids. Telecoil testing has also been
extensively changed.
