The ANSI '92 Test Sequence 

for the FP40/FP40-D Hearing Aid Analyzers

Here is a new test sequence provided free of charge when the Composite Option is installed on new FONIX FP40 and FP40-D Hearing Aid Analyzers.

This test conforms to the ANSI S3.42-1992 standard. It is an appropriate test sequence for non-linear hearing aids. Although it is not required by the FDA, it provides the user with realistic information about AGC and signal processing hearing aids.

Notice the noise sound pressure measurement, the full-on noise gain measurement, the family of 5 curves (50 dB-90 dB or 40-80 dB), and the noise I/O curve. All of these measurements are done quickly and automatically.

Note to non-U.S. users:

Even if you do not normally use the ANSI test sequence, this ANSI '92 is of interest to you. As of this writing, there is no comparable standard written for the IEC and the JIS, so the best way to get this detailed information is by using the ANSI '92, and it is free of charge when the Composite Option and the 1994 CPU board are installed.

All FP40/FP40-D units can be upgraded. Contact the factory or your local Frye representative for details.

The ANSI option also includes ANSI '87 and is available for the 6500-CX.
