The two ears work as a system, providing stereo-

phonic sound everywhere we go. Our brains use

the subtle differences in the timing and intensity

of the sounds reaching each ear to localize

sounds in space and interpret our surroundings.

Modern hearing instruments perform hundreds

of complex operations moment by moment

to adapt to the listening environment. With this

degree of sophistication it is essential that the

hearing instruments work together to provide

an accurate picture of the auditory scene. Fortu-

nately, advanced wireless communication

between hearing instruments allows the ears

to work together in a natural way once again.

Veras – the binaural advantage

Veras allows true binaural hearing with instant

wireless communication between the instru-

ments. This means the user receives an accurate

representation of the spatial dynamics of the

sound scene, in the same way a normal hearing

person would. To achieve this, Veras combines

several fast-acting advanced technologies

that are perfectly coordinated to mimic the

natural hearing process.

performance

With ChannelFree

TM

as a basis, Veras constantly

analyzes the sound environment, amplifying

every detail at the phonemic level. In combina-

tion with automatic technologies, this results

in a very accurate amplication.

•

Binaural environment coordination

The multienvironment functionality in Veras

incorporates rapid binaural detection and

coordination of the amplication parameters in

each ear. Interaural time and level differences

between the ears are preserved to improve the

user’s ability to localize sounds in the constantly

changing auditory scene. Coordinated shifts

in the instrument parameters provide a smooth

hearing response at all times.

•

Binaural wideband processing

There is much evidence that an extended

bandwidth provides high-frequency cues

that are vital to localization and to speech

information. Veras amplies up to 10 kHz,

allowing full broadband benets.

•

Binaural feedback cancellation

The binaural communication in Veras allows

feedback detection to be coordinated between

the instruments. This means that if a feedback-

like signal is detected in both instruments at

the same time, it will not be judged as feedback,

avoiding unnecessary limiting of the signal.
