DirectionalityDirectionalityDepending on the types and number of microphones a hearing aid has, the hearing aid may be able to boost sounds from specific directions (by reducing sounds from other directions). This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.
Front FocusFront FocusA high resolution binaural beamformer directional microphone program.Synchronized SoftSwitching™Synchronized SoftSwitching™SoftSwitching (synchronized between ears) uses sound level and speech detection algorithms to decide when directionality is likely to be advantageous in a certain listening environment. It also offers the same four selections of MultiScope beamwidth settings: the default AutoScope, Narrow, Medium and Wide. The SoftSwitching mode differs from MultiScope Adaptive Directionality in that it uses slower transitions between directional settings and the omnidirectional setting, which is sometimes more comfortable and preferable among certain hearing aid users.
Binaural OneMic directionalityBinaural OneMic directionalityEach CIC receives the sound and information not only from its own microphone but also from the microphone of the other hearing aid. This creates a virtual four-microphone network, allowing the pair of hearing aids to create a directional beam. In addition, the natural pinnae effect of the outer ear supports this directionality and makes the listening experience even more natural.

NoiseTracker™ II: 5 settingsNoiseTracker™ IINoiseTracker II uses a technology called spectral subtraction. Spectral subtraction works by subtracting the short-term noise spectrum from the signal, leaving only the speech portion behind ...

Wind Noise ReductionWind Noise ReductionAs wind blows against the microphones of hearing aids, unpleasant noise may be generated. Some hearing aids have the ability to recognize this wind noise and reduce its level. Such reductions may also affect the audibility of desired sounds, like speech.
Wind Guard: 3 settingsWind GuardWhen no wind noise is found, the hearing aid constantly updates and stores the sound input levels in each Warp band. Then, when wind is present, WindGuard calculates the amount of gain reduction needed to return to the stored level of the specific bands affected by wind noise.
