FONIX 7000 Hearing Aid Analyzer
were implemented and tested on other Frye instruments. The FP40 analyzer
introduced “function buttons” that adapt to handle the specific needs of each
test screen and sequence. The FP35 analyzer added help screens and local
menus to make the analyzer more intuitive and easier to use.
The lessons learned in the FP40 and FP35 analyzers have been incorporated into the
7000 Test System. It is hoped that these improvements will make the 7000 flexible
enough to adapt to any new test procedures as they become needed with the chang-
ing testing requirements of the hearing aid industry
1.2 Basic Test Functions
The basic 7000 can perform the following coupler tests:
• Pure-tone signal measurements
• Composite and Digital Speech signal measurements
• Phase measures for binaural hearing aid pairs
• Group delay (processing delay) measurement of digital hearing aids
• Battery Current as a function of amplitude and frequency
• I/O Curves
• Attack and Release
For both composite and pure tone measurements, the following are possible:
• Special CIC hearing aid coupler measurements
• Behind the ear (BTE), In the ear (ITE), in the canal (ITC), Open ear, and
body hearing aid measurements
• Choice of either IEC 60118-7 or ANSI S3.22-2003/96/87/92 standard tests
(All tests can be installed as options)
An additional function that comes standard with the 7000 is RS232 communication
with an external personal computer. This allows remote operation of the analyzer
from the computer, and lets you save test results onto your computer’s hard drive.
Firmware upgrades to the 7000 Test System can also be performed though the com-
puter.
1.3 Options
The 7000 test system has the following software (and hardware) options avail-
able:
Real-Ear Option
The 7000 test system can be ordered with the Real-Ear Option so that tests can
be done on the hearing aid while it is in the client’s ear. These measurements
are also commonly called “probe measurements” because they are performed
