The Benefits of Digital hearing instruments
GN ReSounds digital hearing instruments offer the following benefits. Each benefit is the result of a distinct software program contained within the instrument, running in parallel with other programs.
Exceptional sound quality
The GN ReSound microprocessor drives 14 individual compression bands, grouped into six adjustable regions to facilitate the fitting process. This large number of adjustable bands allows GN ReSound digital instruments very selective compression characteristics - in essence, more colors on the palette with which to recreate the natural sound picture and meet individual comfort needs.GN ReSound's unprecedented use of the Fast Fourier Transform (FFT) algorithm, a staple of audio and recording industries, ensures overlap between compression bands to eliminate distortion.
GN ReSound instruments also offer the largest dynamic range of any hearing instrument - 90 dB, versus the typical 70 dB range - to capture the full range of sound.
GN ReSound's digital sound processing closely mimics
the function of the human ear by dividing the hearing spectrum into 14 independent frequency bands,
each providing the processing necessary to automatically adjust the loudness and compensate for hearing
impairment.
Elimination of feedback.
GN ReSound digital hearing instruments offer something entirely new: active, "search and destroy" feedback elimination. The instruments continually monitor incoming signals for the presence of feedback (whistling) and crush it before it becomes audible - with no reduction in hearing instrument performance. Thus they solve one of the oldest problems associated with hearing instrument use.

eliminates annoying whistling caused by feedback
Focused listening in noisy surroundings
GN ReSound digital instruments offer dual-microphone digital directional amplification. This provides them the ability to focus on sounds directly in front of the user - a proven method of improving speech understanding amid noise.
GN ReSound digital directional amplification helps
focus amplification for better understanding in difficult listening environments, such as restaurants.
Noise reduction for improved listening comfort
A GN ReSound digital instrument can actually differentiate between sounds commonly regarded as noise - engines, fans, the babble of many voices - and the sound of a single voice. The instrument will dampen the noise, but not the individual voice. This noise reduction works across 14 frequency bands, for precision performance.
GN ReSound's multi-band noise reduction enhances
clarity of speech and the overall sound quality in both quiet and noisy environments by automatically
suppressing background noise such as machinery, air conditioning and traffic.
In addition to the features listed above, GN ReSound’s Canta digital hearing instruments offer:
- 3D Digital technology for all-round wider, clearer sound
- New Digital Dynamic Directionality system that combines Adaptive Directionality with Active Microphone Matching to ensure optimum speech clarity in background over the instrument’s entire lifetime
- New, exclusive “LASER” system for superior sound quality, speech clarity, sharpness and listening comfort using 64-band Spectral Enhancement with 14-band syllabic noise reduction
