Fine adjusting the speech intelligibility

The speech intelligibility can be enhanced individually on the trans-
mitter (see page 17). There are the following settings:

Compression (settings 1 and 3)

Deterioration of the ability to hear quiet sounds as well as loud ones is
a typical symptom of old age. Compression compensates for these
volume differences by boosting the volume of quiet sounds and
reducing the volume of loud sounds if necessary. 

Compression seems to put the speech in the foreground, making it
easier to understand. 

Compression is self-regulating; once it has been activated, it is not
necessary to make any other settings.

Treble boost (settings 2 and 3)

Another typical age-related phenomenon is the deterioration of the
hearing with regard to high frequencies. However, high frequencies are
important for the intelligibility of speech. 

The treble boost makes the speech clearer and easier to understand.

With the treble boost (settings 2 and 3), additional fine adjustment is
possible using the treble boost control 

E

 at the rear of the transmitter.
