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.

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.
No
Yes
Echo ReductionEcho ReductionThis feature improves speech audibility by reducing the “blurring” of speech sounds that can occur in the presence of echoes.

EchoShieldEchoShieldDedicated program for reverberant environments.
Extended bandwidthExtended bandwidthHearing aid provides amplification at frequencies (pitches) higher than the typical hearing aid.
No
12kHz
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.
No
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.

Processing ChannelsProcessing ChannelsThese are all the frequency-divided sections the hearing aid is able to examine at a single time. The hearing aid uses this information to determine whether the contents of each section are noise, speech, or something else and amplify the sound in each section accordingly.

Direct Streaming: 5/5Direct StreamingSignia Nx hearing aids can be connected directly to Apple devices for phone calls and audio streaming – without additional accessories. With the StreamLine Mic accessory, direct streaming is possible also from Android devices. With the StreamLine TV accessory, high-quality stereo sound can be streamed directly to Nx hearing aids.
Tinnitus ReliefTinnitus ReliefTinnitus, or ringing in the ears, can be addressed by hearing aids in several different ways, such as introducing a soft therapeutic signal or targeted notched noise.

Sound Clarity: 5/5Sound ClaritySound Clarity provides lifelike sound which covers the full spectrum of wearing situations. Exceptional clarity is achieved with features such as: HD Spatial, extended dynamic range, extended bandwidth, EchoShield, HD Music, eWindScreen™, speech and noise management and feedback cancellation.
Wind Noise ReductionWind Noise ReductionAs wind blows against the microphones of hearing aids, unpleasant noise may be generated. Some hearing aids have the ability to recognize this wind noise and reduce its level. Such reductions may also affect the audibility of desired sounds, like speech.
