TwinPhoneTwinPhoneTwinPhone is the optimal solution for these wearers. It is automatically activated by a magnetic signal, so the wearer hears the caller in both ears for better understanding.
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.

Feedback SuppressionFeedback SuppressionIf any sound amplified by the hearing aid escapes the ear canal, it may reach the hearing aid’s own microphone and cause a harsh whistling noise. Some hearing aids are able to recognize when this feedback occurs and reduce or eliminate it.

Feedback cancellationFeedback cancellationHigh-speed monitoring and control of feedback risk in individual processing channels.
Frequency LoweringFrequency LoweringUnderstanding certain speech sounds is dependent on the high frequency parts of these sounds. For individuals with high frequency hearing loss, this feature can take high frequency speech information and move it to lower frequencies where it will be audible.
SoundRecover2SoundRecover2The new SoundRecover2 algorithm aims to restore the audibility of relevant high frequency sounds while leaving intact the low frequency structures important for good sound quality. The new frequency lowering scheme retains the essence of the original SoundRecover, utilizes an adaptive algorithm and an additional cut-off frequency in order to successfully extend these benefits to those with more extreme severe-to-profound hearing loss.

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.

Spatial Noise CancellationSpatial Noise CancellationThis feature recognizes where sounds are coming from and can reduce noise coming from behind or to the side of the listener. This helps the listener focus on the speaker, usually in front of them.
SNR-BoostSNR-BoostThe SNR boost is what we call a "spatial noise canceller." This means that when the hearing instruments are in the UltraZoom mode, they will analyze the signal to noise ratio in both the front and back planes. Then, the system will look for where there is a poor signal-to-noise ratio and it will apply another level of noise canceling on top of the standard noise canceling that is only active when the aids are in the directional mode. This goes beyond what we are already doing with multichannel adaptive directionality in terms of improving signal to noise ratio. Essentially, this minimizes noise for the client when they're in a very noisy environment. UltraZoom is part of the universal automatic program, SoundFlow. - Source: http://www.audiologyonline.com/interviews/interview-with-nathan-schau-au-1334
