From our twentieth year, some hair cells in the inner ear, responsible for the perception of high tones that die.
This high tone hearing loss leads initially difficult to distinguish the consonants, which in turn leads to less well understood and wrong interpretation of certain statements or sayings.
'Hearing' is simply the perception of sound. Even with a significant hearing loss, we can still perceive sounds or hear.
A listening device lets you certainly hear better in the sense that you hear sounds a lot more help than without. A classic instrument will indeed be back for sure that everything is audible.
Mean
By "understand" it is not only to observe but also to distinguish different words and sounds (eg the distinction between 'container' or 'roof').
As consonants (b, d, k) are located in the treble region. As vowels a, o, oe earlier in the bass region. With age we lose little by little the ability to perceive the treble and as such the perception of consonants.
Furthermore, there situations with background noise especially in low tones. That bass create a disturbing (masking) effect on the high-frequency consonants. Hence the first characteristics of a hearing to identify himself in communication with background noise conditions.
You hear what is said but everything is properly understood as there is no more.
In a first phase we can describe as an impairment loss of selectivity which means less well understood.
In subsequent phases will total audience (including middle and low tones) step by step backwards so there is actually louder voice you want something clearly understood.

Intelligibility problems caused by the first high-frequency hearing decrease will mainly be observed in the presence of background noise. Later, the person in question is also difficult conversations remotely, and even in a quiet area to follow. There is thus an important difference between 'hear' and 'understand'.
