116 FONIX 7000 Hearing Aid Analyzer
• OSPL90 Sweep Meas Delay—The delay between frequencies in the
OSPL90 sweep.
• Res Crv Sweep Start Delay—The delay after the first tone is presented in
the response curve (at 50 or 60 dB SPL) sweep and before the first mea
-
surement is taken.
• Res Crv Sweep Meas Delay –The delay between frequencies in the
response curve (at 50 or 60 dB SPL) sweep.
• Misc Start Delay—The delay after the first tone is presented and before
the first measurement is taken in the HFA/SPA, reference test gain, equiv
-
alent input noise, and harmonic distortion measurements.
• Misc Meas Delay—The delay between frequencies in the measurements
mentioned above.
Note: ANSI 87 combines the “OSPL90” and “Res Crv” delays into the “Sweep
Start” delay settings.
AGC Settings
The purpose of the following settings is identical for each I/O frequency.
• AGC frequency—Status of the I/O test at the selected frequency. Turn the
test ON or OFF.
• I/O Start—The delay after the first tone is presented in the I/O sweep and
before the first measurement is taken.
• I/O Meas—The delay between frequencies in the I/O sweep.
• Attack Window—The amount of time the analyzer measures the attack
time of the hearing aid. Select a time that is at least twice as long as the
attack time specified by the manufacturer.
• Release Window—The amount of time the analyzer measures the release
time of the hearing aid. Select a time that is at least twice as long as the
release time specified by the manufacturer.
Note: ANSI 87 only measured I/O at 2000 Hz, and the Attack and Release win
-
dow settings are not available.
Misc Settings
• Print Label—Status of the printing label. Choose ON or OFF.
• Printer—Printer used for printouts. Choose INTERNAL or EXTERNAL.
