An estimated aided threshold curve is calculated by shifting the unaided threshold
curve upward by the REIG. This estimate assumes
a) the
unaided threshold is a
sound-field threshold
and b) a
linear aid
(i.e. REIG doesn’t depend on level).
The REUR curve uses the right-hand SPL scale and is shown for reference only.
