2.5 Display & Data
This section describes the Curve Characteristics Box that is common to every
measurement screen, and the data display that shows the numerical data of the
response curves in the Coupler screen and the real-ear measurement screens.
2.5.1 Viewing the Curve Characteristics Box
Each measurement screen has a Curve Characteristics Box that tells you different
information about each measured curve. It has several different columns of
data: Curve Name, Curve Title (real-ear only), Source Type, Source Transducer,
Source Amplitude, RMS Out, Correction Factors (COR, coupler only) and NR
(Noise Reduction). Figure 2.5.1 shows an example.
Figure 2.5.1—Curve Characteristics Box
Curve Name: This identifies the name of each curve. The first letter is derived
from its measurement type—coupler (C) or probe (P). The second letter is
derived from its ear—left (L) or right (R). (Coupler curves can also be labeled
A and B.) The third letter is the number of the curve. CR1 is the first coupler
curve for the right ear. PL2 is the second probe curve for the left ear.
Curve Title: This identifies the title of the real-ear curve. It is only available in
the real-ear measurement screens. Here are the possible titles: REUR (real-ear
unaided response), REAR (real-ear aided response), REIG (real-ear insertion
gain), TARG (real-ear target), HTL (hearing threshold level), UCL (uncomfortable
level).
Source Type: This identifies the type of source used to make the curve. Each
curve is identified by three letters.
First letter:
C = Composite
P = Pure-tone
D = Digital Speech
