C-ISP

Our new and powerful C-ISP platform puts us in a leading position in terms of connectivity, the retention of important psychoacoustic cues, and sound quality features, including enhanced bandwidth and impulse sound handling.

With a 60% higher signal processing capacity, the new C-ISP technology takes our acclaimed ISP platform a step further. In the new C-ISP unit, the well-known technology of ISP is placed in a new, permeable structure with smooth exchange of information.
 

Even better results coupled with a partner

The C-ISP unit is designed to perform well on its own, but it produces even better results coupled with a partner in a binaural fitting.

Synchronisation of important audiological features, user remote control of selected features, and high-definition audio streaming from external sources are all made possible by the exchange of data between the two hearing aids.


C-ISP enables CLEAR440 to coordinate features, calibrate decision-making and communicate to the user.

The signal analysis part of the C-ISP platform contains information about speech and noise ratio and level, acoustic feedback and signal origin.

It also contains the Steep Gradient Detector (the detection mechanism of TruSound Softener), which will catch sudden impulse sounds in the broadband signal and determine if they are noise or speech.

All sound processing takes place in the signal processing unit. The new C-ISP signal processing unit is able to incorporate data collected by the opposite hearing aid in the processing. We call this capacity for continual adjustment of discrete hearing aid functions both within hearing aids and between them InterEar. 

InterEar
InterEar makes it possible to retain a number of important psychoacoustic cues. These cues are provided by the signal processing features below.

• InterEar TruSound Compression preserves the Interaural Level Difference (ILD), which is an important psychoacoustic cue for the localisation of sound coming from the sides
  
  
• InterEar Speech Enhancer aims at improving speech perception in noise by singling out the dominant speaker in situations where several speakers are talking at once
  
  
• Digital Pinna recreates the natural pinna shadow effect, which is an important cue for the listener to know if a sound is coming from in front or behind
  
  
• InterEar feedback Cancelling minimises the risk of continuous steady sounds (also known as auto-correlated sounds) being attenuated by the feedback system because they are mistaken for feedback
  
  

SmartSpeak and SmartTone were introduced with the dual ISP platform. These are carried over to the C-ISP platform with new SmartSpeak messages.

The ability to exchange information via the WidexLink technology also makes it possible to create a stereo-like experience when the hearing aid user is listening to the Zen styles in a pair of coordinated CLEAR440 hearing aids. This may create a richer experience for the user when listening to the Zen styles.

The My Profile system is a new unit introduced with the C-ISP platform. The audiological profile of the user, his personal preferences, and fitting setup are stored in this unit.

The selection of listening programs and compound programs is also done via this unit. And direct audio input from FM or Tele is received here before being moved elsewhere for further processing in the C-ISP. 
 

The platform for WidexLink

C-ISP is the platform for our new, proprietary WidexLink technology, which has been developed specifically for data exchange and audio streaming in a hearing aid system.

The exchange of information between the C-ISP platforms in a binaurally fitted pair of CLEAR440 hearing aids happens via WidexLink. Data from the C-ISP unit in the other hearing aid are transmitted as an InterEar percentile data exchange.
