2.3.1.1 Pure-tone settings
There are several different settings available for pure-tone sweeps. You can
change all of them in the Setup menu (see Section 2.2). Some of these settings
are also available in local menus. Here is an explanation of the pure-tone set-
tings.
NOISE RED (TONE): The amount of noise reduction used in pure-tone mea-
surements. This is set independently for real-ear and coupler measurements.
See Section 2.3.1.2.
SWEEP START DELAY: The amount of time the 7000 test system presents the
first tone in a pure-tone sweep. See Section 2.3.1.3.
SWEEP MEAS DELAY: The amount of time each subsequent tone is presented
before the measurement is made in a pure-tone sweep. See Section 2.3.1.3.
MISC START DELAY: The amount of time the 7000 test system presents the
first tone in one of the following measurements: reference test gain measure-
ments (in automated test sequences), averaging, harmonic distortion measure-
ments, equivalent input noise, and single-frequency telecoil measurements. See
Section 2.3.1.3.
MISC MEAS DELAY: The amount of time each subsequent tone is presented
before the measurements is made in one of the measurements listed above. See
Section 2.3.1.3.
I/O START DELAY: The amount of time the first tone in an I/O sweep is pre-
sented before the measurement is made. See Section 2.3.1.3.
I/O MEAS DELAY: The amount of time each subsequent tone in an I/O sweep is
presented before the measurement is made. See Section 2.3.1.3.
DISTORTION: The type of harmonic distortion measurement made during a
pure-tone sweep. See Section 2.3.1.4.
STATIC TONE: A continuous tone (or series of tones) presented in the Coupler
screen when a pure-tone sweep, Composite, or Digital Speech signal isn’t run-
ning. This can be set to SINGLE for a pure-tone signal and AVG for a running
three frequency average.
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:
