REF MIC—Status of the reference microphone during real-ear measurements.
NOISE RED (TONE)—The amount of noise reduction used in pure-tone real-ear
measurements. See Section 2.5.1.3.
NOISE RED (COMP)—The amount of noise reduction used in Composite or
Digital Speech real-ear measurements. See Section 2.5.2.3 for more information.
OUTPUT LIMIT— The maximum dB SPL value that the analyzer will allow
when taking real-ear measurements. When this value is exceeded, the measure-
ment will automatically stop and the source will turn off in order to protect the
patient.
ASSESSMENT—The transducer used to take RECD/REDD and audiometric mea-
surements.
TELECOIL—Status of the real-ear telecoil measurements. OFF disables telecoil
measurements in the real-ear measurement screens. TMFS EAR enables the use
of a Telewand connected through the earphone jack. TMFS SPKR enables the
Telewand through the speaker jack (new rear panel only). There is no support
for the external telecoil board in real-ear measurements. See Section 2.5.8 for
more details.
VISIBLE SPEECH—Display used when the FP35 analyzer is in Spectrum
Analysis mode (requires Composite/Digital Speech Option). BARS displays a
set of vertical bars representing the maximum peaks of the measurements that
reach above the lower limits of the speech banana. AVERAGE displays a long
term average of the response using a peak decay method.
