The Severity counselling overlay shows the degrees of hearing loss as it is
set up in the protocol that is currently in use.
The Max. testable values shows the area beyond the maximum intensity
the system allows. This is a reflection of the transducer calibration and
depends on the extended range being activated.
Selecting HL, MCL, UCL or Tinnitus sets the symbol types that are
currently in use by the audiogram. HL stands for hearing level, MCL stands
for most comfortable level and UCL stands for uncomfortable level. Note
that these buttons show the unmasked right and left symbols of the
currently selected symbol set.
Each type of measurement is saved as a separate curve.
In the Comments section you can type comments related to any
audiometric test. The used space by the comments area can be set by
dragging the double line with your mouse. Pressing the Report editor (1)
button opens a separate window for adding notes to the current session.
The report editor and comment box contain the same text. In case the
formatting of the text is important, this can only be set within the report
editor.
After saving the session, changes can only be made within the same day
until the date changes (at midnight). Note: these timeframes are limited by
HIMSA and the Noah software, and not by Interacoustics.
