How are the Results Stored and Reported?

When the OtoRead is set in its default settings, the instrument will
store the results from one patient (left and right ear) in its non-volatile
memory for subsequent printing. However, the OtoRead instrument
can store up to 250 test results. The results are displayed via the
LCD on the front of the device and are stored in the device's internal
memory. After testing is completed, results can be printed using the
printer. Test results are stored in the non-volatile memory so the
operator can delay printing until a later time if desired.
What Are DPOAEs?
Distortion Product Otoacoustic Emissions (DPOAEs) are
acoustic signals that can be detected in the ear canal of a
person with normal outer hair cell function, subsequent to
stimulation of the auditory system with a pair of pure tones at
frequencies f1 and f2. The resulting emission of interest is the
distortion product tone at the frequency 2f1-f2.
What Are TEOAEs?
Transient Evoked Otoacoustic Emissions (TEOAEs) are
acoustic signals that can be detected in the ear canal of a
person with normal outer hair cell function, subsequent to
stimulation of the auditory system with a series of wideband
clicks.
What Do Otoacoustic Emissions Results Tell Us?
Available evidence suggests that otoacoustic emissions
(OAEs) are generated by the cochlea's outer hair cells, and
that the presence of OAEs is an indication that the outer hair
cells are normal. Although OAE test data provide no indication
of inner hair cell function, or of hearing ability, current research
indicates that the majority of hearing-impaired individuals will
be identified by a simple OAE test. Patients who fail to
generate OAEs should be rescreened and/or referred for
additional audiological testing.
