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.

Remembers adjustments you make with FlexControl and FlexVolume and applies them automatically for a hearing aid more in tune with your preferences.

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.

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. 

When microphones are placed outside the pinna, natural front/back and vertical localization cues can be lost. Real Ear Sound, simulates the performance characteristics of the pinna to restore localization and the ability to experience natural sound perception.

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.

The next generation of SoundRecover further improves speech audibility and utilizes an adaptive frequency lowering algorithm. Sound quality of mid and low frequencies are maintained while high frequency sounds are made audible. This creates an optimal listening experience for more users than ever before.

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.
