Adapts and reduces noise from behind in real time and applies and optimizes the signal-to-noise ratio (SNR) in noisy environments.

Provides optimal gain for speech understanding and listening comfort when engaging in one-on-one conversations in quiet.

Actively reduces noise for increased comfort when no speech is present.

Environmental balance is a volume modification capability in Phonak hearing aids that allows clients to adjust the volume of the streamed signal versus the surrounding environmental sounds by the press of the volume control. 

Directional microphone technology is a proven method of effectively improving speech intelligibility in background noise. UltraZoom is the adaptive multi-channel beamforming technology, automatically available in AutoSense OS or in a manual program.

WhistleBlock differentiates between naturally occurring feedback-like sounds and true feedback. This means increased audibility and sound quality that is free from annoying feedback.

The key feature DuoPhone streams the signal in real time to the other ear so the caller's voice is heard in both ears with an average benefit of 3.1 dB SNR.

A proprietary, multidimensional-weighted algorithm sets an ideal target "acoustic mass" for each vent. The sophisticated 3D modeling software generates an individualized vent. This unique Acoustically Optimized Venting (AOV) value is coded into each instrument and used to optimize the fitting calculation. Occlusion can now be reduced to the lowest level possible. This exclusive Phonak innovation is available in the full range of custom products and styles. It is also available for BTE wearers with a SlimTip, SlimTip Soft, cShell, or xShell.

One-touch controls two. The instantaneous broadband transfer of data between two instruments ensures that volume and program settings are always balanced and synchronized. One touch on the program selection button or volume control results in instant identical change in the other instrument.
