Automated Test Sequences
There are several automated coupler test sequences available for the 7000 hear-
ing aid analyzer. The test sequences present on your analyzer are dependent
upon the features purchased when you ordered your unit. If you would like
access to a test sequence not present on your unit, you can always order an
upgrade. Call the factory or your local distributor for more information.
The following test sequences are available:
• ANSI S3.22-2003 (ANSI 03)
• ANSI S3.22-1996 (ANSI 96)
• ANSI S3.22-1987 (ANSI 87)
• ANSI S3.42-1992 (ANSI 92)
• IEC
• JIS
5.1 ANSI S3.22
The ANSI S3.22 automated test sequences allow you to test hearing aids accord-
ing to the ANSI S3.22 standards. You can use the ANSI tests to control the qual-
ity of the hearing aids that you dispense. Compare the manufacturer’s specifi-
cations with your own ANSI measurements of an aid. If they do not conform
within expected tolerances, you can contact the manufacturer.
There are three different versions of the ANSI S3.22 standard: ANSI 03, ANSI
96, and ANSI 87. This is because the standard periodically gets upgraded by the
ANSI standards committee. After the ANSI S3.22 standard has been updated,
the FDA reviews it and eventually approves it to be used for labeling the specifi-
cations of all hearing aids manufactured in the United States.
The ANSI 96 standard was officially approved by the FDA on March 17, 2000.
This means that any hearing aid designed after this date must be labeled to the
ANSI 96 standard. However, if a manufacturer designed a hearing aid before
this date, they can continue labeling newly manufacturered aids of the same
design to the older ANSI 87 standard.
ANSI 03, which was approved by the FDA in November of 2005, is the newest
version of the ANSI S3.22 standard.
