Software Features

B3 Powered by Bose
Silk X
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
20
Adjustment SynchronizationAdjustment SynchronizationThis feature allows for a more pleasant listening experience by ensuring that both hearing aids process sound the same way. If one hearing aid changes its processing in response to noise or speech, it will send a wireless signal to the other hearing aid so both process sound in the same way.
No
Ultra HD e2eUltra HD e2eUltra HD e2e providers a continuous full-bandwidth audio exchange. This powers OVP, beam-forming directionality, hearing aid adjustment syncing, and more.
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.
Yes
Echo ReductionEcho ReductionThis feature improves speech audibility by reducing the “blurring” of speech sounds that can occur in the presence of echoes.
No
EchoShieldEchoShieldDedicated program for reverberant environments.
Extended bandwidthExtended bandwidthHearing aid provides amplification at frequencies (pitches) higher than the typical hearing aid.

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.
No
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.
Yes
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.
No
Frequency CompressionFrequency CompressionImproves the detection of speech sounds for wearers with reduced high frequency hearing thresholds. Frequency compression is selectively activated based on audiological criteria.
