Adaptive feature example 2: Demonstrating
Noise Reduction.
Red Curve: Unaided and Aided with
Noise Reduction feature OFF.
Blue Curve: Unaided and Aided with
Noise Reduction feature set to MAX.
Dynamic range.
The dynamic range is the range
between the softest sound the ear can
detect and the loudest sound the ear
can tolerate (thresholds and UCLs).
Use the Speech Mapping graph to
explain the consequences and
limitations of narrowed dynamic ranges.
Demonstrate the difference between a
normal dynamic range (normal hearing
to UCL) and a narrowed dynamic range
(hearing loss to UCL).
