Adjustment BandsAdjustment BandsThese are frequency-divided sections that can be adjusted in a hearing aid in order to amplify sounds. Although there are rarely more than 10 frequencies measured in a hearing assessment, having more bands that can be adjusted may allow for improved speech understanding and user comfort.
No

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.
Automatic Sound FocusAutomatic Sound FocusAutomatic Sound Focus reduces surrounding noise and adjusts dual microphones toward the direction of speech.
Adaptive Directionality™Adaptive Directionality™Adaptive Directionality slowly transitions between omnidirectional and directional settings based on an analysis of the acoustic environment.Binaural Directionality™ IIIBinaural Directionality™ IIIBinaural Directionality III provides the ultimate balance for supporting natural hearing: a signal-to-noise ratio improvement similar to bilateral directional microphones and a significant benefit in ease of listening compared to other directional microphone strategies.
Environmental AdaptationEnvironmental AdaptationThe hearing aid can detect different acoustical environments, like speech in noise, and adjust the sound of the hearing aid accordingly to drive comfort or speech understanding, etc.
No
Environmental OptimizerEnvironmental OptimizerProvide automatic adjustment of hearing instrument settings.
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.
Yes
DFS Ultra IIIDFS Ultra IIIReduces feedback while preserving amplification without compromising sound quality.
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.
No
Sound ShaperSound ShaperSound Shaper is the only frequency compression technology that moves high-frequency sounds down in the spectrum while maintaining a proportional relationship between input and output frequencies. So Sound Shaper improves the audibility of speech cues that would otherwise be lost, while maintaining the best sound quality possible.
