FONIX® 7000 - Frye Electronics

32 FONIX 7000 Hearing Aid Analyzer
RESET FREQ: The frequency the analyzer returns to when RESET is pressed.
AVG FREQS: The frequencies used for averaging in pure-tone measurements.
Each frequency set is represented on the screen by the highest frequency in the
set. The sets are:
HFA (High Frequency Average) 1000, 1600, 2500
SPA (Special Purpose Average) 800, 1250, 2000
SPA 1250, 2000, 3150
SPA 1600, 2500, 4000
SPA 2000, 3150, 5000
IEC–(HAIC) 500, 1000, 2000
Coupler Default Settings
BATTERY MEAS: Status of the battery current measurement. Choose ON or OFF.
BATTERY SIZE: Size of battery used with the hearing aid being tested. Used in
battery current measurements.
NOISE RED (TONE): Amount of pure-tone noise reduction used in coupler measurements.
See Section 2.3.1.1.
NOISE RED (COMP): Amount of composite noise reduction used in coupler
measurements. See Section 2.3.2.1.
RESET SOURCE: The signal type selected in the Coupler screen when the
[RESET] button is pushed.
DISPLAY: Display of the Coupler Multicurve screen. Choose between Gain and
SPL.
CURVE LABEL: Label used for the two available “ears.” Choose between LEFT/
RIGHT, and A/B.
GRAPH SCALING: Scaling used when making measurements. NORMAL scales
to the upper-most curve displayed. AUTO scales to the current selected curve.
COUPLER TYPE: The type of coupler being used in making sound chamber
measurements. Selections of CIC and MZ turn on corresponding software correction
factors (see Sections 3.6 and 3.7). A selection of NONE or 2cc does not
apply correction factors to the curve.
STATIC TONE: Status of individual frequency measurement. Choose SINGLE
to emit a static tone in between composite measurements or pure-tone sweeps.
Choose AVG to emit a three frequency average between other measurements.
Choose OFF to turn off this measurement.
DISTORTION: Type of harmonic distortion used in a pure-tone measurement.
Choose between 2nd, 3rd, and TOTAL. See Section 2.3.1.3.
