REOR measures the effect on the natural external ear effects resulting from inserting an
ear mold or a hearing instrument, before it is turned on, into the ear canal. The REOR I
also referred to as Insertion Loss REOR is also useful for validating the effectiveness of
venting or canal length changes to the mold.
The Real Ear Occluded Gain (REOG) is the difference in decibels, as a function of
frequency, between SPL in the ear canal and SPL at the reference microphone at the
entrance of the ear canal with the hearing aid in the ear and turned off. For each REOR
measurement curve, the corresponding REOG curve is calculated and automatically
plotted to the REOG screen. The REOG function is useful in determining the acoustic seal
of a hearing aid, relative to a sound field outside the ear.
Some clients report they seem like they are “speaking in a barrel” or “feel blocked up”.
These are signs of a build up of low frequency energy in the ear canal. This excessive
occlusion can be measured objectively in the Occlusion Effect task.
The Real Ear to Coupler Difference (RECD) is used to simulate real ear measurements by
coupler measurements and is useful when fitting children or
“difficult” to fit patients. See
the section on RECD later in this manual for more detail.
Sample REM Screens
The Avant REM Speech system supports all current ANSI and IEC Real Ear Measurements.
The screenshots below were made using the software defaults. These defaults set the test
parameters for each test according to these standards, however the test environment is fully
configurable to meet individual professional’s needs.
