Product Features:
Phonak has pioneered tremendous advances in signal processing that allow Certéna to provide freedom from feedback, clear speech understanding and comfortable listening in changing environments.
WhistleBlock Technology – freedom from feedback
A whistling sound called feedback is one of the most common annoyances of hearing instruments. Thanks to
WhistleBlock Technology, Certéna functions reliably without the annoyance of feedback.
No more whistling
Instantly and accurately differentiates feedback from other tonal sounds like those in music
Self-determines when it is needed and automatically activates and adjusts
Sound quality remains excellent and speech is clear
Permits more volume without feedback than any competitive system
Digital AudioZoom – clarity in noise
Imagine yourself in a restaurant, at a party or a family gathering. In these situations there is usually a lot of
background noise that might make it difficult for you to understand conversations. Certéna uses the only
proven method of enhancing speech understanding in noise – directional microphone technology.
Zooms in on the speech you want to hear while reducing the noise
Automatically activates when needed
NoiseBlock Processing – comfortable listening
Environmental noises like motors, fans and engines can be quite uncomfortable. NoiseBlock Processing
effectively diminishes these bothersome sounds
Continuously analyzes the environment
Recognizes the differences between speech and other sounds and automatically reduces only the noise
