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.

Extended Dynamic RangeExtended Dynamic RangeExtended dynamic range typically makes louder sound clearer. This may help with the reproduction of loud music or loud speech in a very noisy environment.
Clear DynamicsClear DynamicsClear Dynamics expands the input dynamic range, processing input sounds up to 113 dB SPL, to provide better sound quality without distortion and artifact at loud input levels, while still keeping the sound quality of soft input levels intact. Clear Dynamics has an operating range from 5 to 113 dB SPL. With speech cues preserved at high input levels, users enjoy a better listening experience without distortion even in loud environments. Clear Dynamics is especially valuable for users when listening to music or in conversations in busy, dynamic environments, where peaks can often be louder than the available input dynamic range.
Yes
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 ShieldFeedback ShieldEmploys an ultra-fast and effective feedback management system that prevents feedback without compromising sound quality or audibility.MoreSound Optimizer™MoreSound Optimizer™MoreSound Optimizer (MSO) and Feedback shield work together to counteract acoustic feedback from the receiver to the microphone to prevent audible feedback and gain reductions.
