WIDEX CLEAR440

The platform: C-ISP

CLEAR440 is a unique hearing aid – powerful on its own but strongest when coupled. The C-ISP communication platform in CLEAR440, with a total of three individually designed chips, makes this new power possible.

C-ISP combines and manages a series of sound analysis and processing functions for clearer hearing.

Moreover, C-ISP has the capacity for continual adjustment of discrete hearing aid functions both within hearing aids and between them – what we call InterEar (IE). The result is an unequalled balance of performance that replicates the natural hearing experience even more closely.

WidexLink
Our revolutionary WidexLink™ is the first wireless connection designed especially to allow both InterEar data transmission, synchronisation and digital wireless transmission of audio to and between hearing aids.

And uniquely, proprietary WidexLink can deliver artifact-free audio transmission in real time.

Sound perception and sound quality:

• IE TruSound Compression: IE TruSound Compression amplifies soft, normal speech and loud inputs and coordinates gain changes between right and left hearing aid. Thereby the natural interaural level difference (ILD) between the ears can be preserved, resulting in better localisation of sound direction for the user
  
  
• IE Speech Enhancer exploits the binaural percentile information to enhance speech above the threshold and attenuate background noise below it. In this way, coupled WIDEX CLEAR™440 hearing aids attempt to single out a dominant speaker in background noise.
  
  Digital Pinna: An electronic pinna characteristic that recreates the natural shadowing effect of approximately 4 dB to achieve a more natural front focus.
  
  It means the Digital Pinna helps the user in determining which direction sound is coming from.

  Sounds from behind are attenuated by 3-4 dB relative to soundscoming from the front.
  

• The groundbreaking TruSound Softener is designed to handle sudden impulse sounds – such as the chinking of porcelain or the slamming of doors - with comfort and clarity. Once detected, any disturbing or irrelevant transient is handled by the TruSound Softener in CLEAR440 TruSound Compression via a swift forewarning algorithm.
  
  

Freedom of choice

The WIDEX CLEAR™440 series gives the user freedom to choose from a vast variety of features:

• IE Feedback Cancelling: a multidirectional adaptive feedback cancelling system that minimises whistling. In CLEAR440 the new InterEar (IE) data exchange is incorporated, coordinating information on feedback occurrence between both ears. The potential in InterEar data exchange is to make the IE Feedback Cancelling more agile in handling acoustic feedback in situations where the acoustic property of the feedback signal resembles that of musical instruments.
  
  
• Enhanced bandwidth: CLEAR440 supports the widest bandwidth currently available in a hearing aid, including an enhanced low frequency bandwidth (down to 70Hz) for the full enjoyment of music.
  
  
• FreeFocus in CLEAR440 allows users to hear in selected directions – without them needing to turn their heads
  
  
• Definable volume control: CLEAR440 offers a choice between 1, 1.5 and 2 dB steps
  
  
• IE Zen – natural relaxation: Our popular Zen dedicated relaxation and tone program has been enhanced. Sound generation is distributed between the hearing aids (InterEar) – some instruments in one ear, different instruments in the other
