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.

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.Ultra FocusUltra FocusThe user-controlled Ultra Focus uses a powerful combined directional pattern from both hearing aids to focus on the person in front of you.
Ear SimulationEar SimulationThe outer ear, or pinna, can have a significant effect on the frequency shape of sound arriving at your inner ear. Some hearing aids mimic the "pinna effect" when producing sound, to deliver more natural sound to the listener.

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 ... ReSound’s NoiseTracker II is able to use spectral subtraction successfully because the Environmental Classifier has identified speech and noise so precisely.
Occlusion ReductionOcclusion ReductionWhen ears are plugged, or occluded, by hearing aids the low frequencies from one’s own voice are amplified and may be uncomfortable. This effect is typically reduced in hearing aids through venting or open-fit models. In some cases the perception of occlusion may also be reduced through software by adjusting the acoustic output of the hearing aid.

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.
