OM001-16 Otowave 102 Operating Manual Page 33
Ear volume measurement range
and accuracy
0.2ml to 5ml +/- 0.1ml or +/-5%
(whichever is larger) over entire range
Typically 200-300daPa/sec; dependent
on ear/cavity volume
Pressure limits (safety cutout)
Reflex tone levels and accuracy
(referenced to 2ml calibration
volume - compensates for
measured ear volume)
102-1: 1kHz (+/-2%)
102-4: 500Hz,1kHz,2kHz,4kHz (+/-2%)
Configurable over range 70dB
to100dBHL +/-3dB (4kHz restricted to
95dBHL)
Number of reflex levels (see
Section 3.3)
Four: 100dB with 5dB or 10 dB steps;
95dB, 90dB or 85dB with 5 dB steps
Reflex pass/fail at each level tested;
maximum amplitude of each reflex;
nominal pressure used for the reflex
test (computer display only)
Pressure used for reflex
measurement
Pressure at tympanogram peak, or at
0daPa (if no peak found)
Stimulus presented at all levels, or
stimulus ceases when a reflex is found
Reflex detection threshold and
accuracy
0.01ml to 0.5ml +/-0.01ml (configurable
in 0.01ml steps)
Number of records stored in
Patient Database
Any recording can be stored once the
tympanogram is viewed. Patient Initials
(A-Z, 0-9, ā-ā) must be entered before
storage.
Patient Initials, Tympanogram and
Reflex graphs and analysis for Left Ear
and/or Right Ear, Time and Date of
recording, which ears were tested,
