A loud environment with background noise has always been a nuisance to hearing instrument users.
As much as the conversation, hearing instruments amplify environmental noise as well.
Siemens has worked for years to attenuate background noise as much as possible for hearing instrument
users and to positively influence the intelligibility of speech in such noisy environments.
Effective noise reduction systems are required for different situations like:
Sounds created by a ventilation system
Sounds inside a moving automobile
Sounds on a busy street.
Siemens engineers have continually developed speech in noise managements systems in hearing instruments.
With the CENTRA™ family, Siemens offers a new component in speech and noise management, SoundSmoothing™.
Together with Noise reduction and speech enhancement, all three components
consistently active and
operate parallel to each other for the best customer satisfaction.
The animation below demonstrates how two components work together to alleviate speech understanding in noisy situations.
The component "Noise reduction" takes care of stationary noise. The component "Speech enhancement" is employed when speech
and noise are present at the same time. Together both components ensure best speech intelligibility in noise. Noise
reduction and speech enhancement are available in most Siemens hearing instrument families (CENTRA, ACURIS, ACURIS Life,
ARTIS & ARTIS e2e, CIELO and TRIANO)
