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.
