Speech in quiet

The optimization for this environment slightly

increases the amplication for speech signals

when speech is detected in a quiet environment.

This ensures that speech is emphasized and

makes listening easier.

Comfort in noise

Most people don’t like to listen to background

noise. When this environment is chosen for

optimization, the overall gain is slightly reduced

to provide extra comfort in addition to the noise

reduction system when noise is the only signal

detected.

Comfort in quiet

Many people feel they don’t need their instru-

ments in a quiet environment and may switch

them off. The optimization for comfort in quiet

slightly reduces the gain when quiet environ-

ments are detected, for extra listening comfort.

With the Environment Optimizer, Veras can

be further customized to your client’s listening

needs.

The multienvironment program in Veras matches

incoming signals with one of four listening

environment classications. Although these four

listening environments handle most everyday

listening situations quite well, there are times

when the client might benet from enhancement

of a particular environment.

The Environment Optimizer allows you to

select one of the four listening environments and

apply a special setting to this environment. The

optimization is automatically activated whenever

the chosen environment is detected.

Speech in noise

If this environment is chosen, Veras automatically

fades to the optimized settings whenever speech

is detected in the presence of loud background

noise. Research shows that hearing-impaired

people lose their ability to extract information

from the temporal ne structure of speech

(Moore, 2008). This means they rely heavily on

the envelope of the speech signal. In the

optimization mode, more envelope information

is made more available to the listener.
