At ReSound, we believe that hearing should sound natural, feel natural and connect you naturally. All our hearing aids are packed with features that allow you to hear your best and provide you our best comfort.
Take a moment to review our features, including a short explanation and then view a supporting whitepaper.
Speech Intelligibility Feature
Intelligent Focus is designed for use in moderate to loud noise situations, when users need to maximize audibility for speech directly in front of them, and cut out as much noise as possible. It combines our strongest beamformer (Clear Focus) with Intelligent Noise Tracker, which reproduces a less noisy signal based on training via artificial intelligence technology. This results in more contrast between speech and unwanted noise for the listener.
End user benefit
Intelligent Focus can only be activated in a Hearing In Noise program, so that its use remains intentional based on the user’s needs.
Speech Intelligibility Feature
In particularly noisy situations, the user may want an extra boost in order to listen only to a talker directly in front of them.
Clear Focus creates our strongest beamformer yet by activating directionality across more channels for maximum enhancement of sounds from the front.
End user benefit
Located in the app and with a very easy-to-access interface, users can control their sound experience to focus on what they want to listen to in high noise environments.
Noise Reduction Feature
Intelligent Noise Tracker reduces unwanted background noise without degrading the quality of speech. Artificial intelligence technology was used to train the feature to estimate a “clean” signal without noise based on exposure to 13.5 million speech sentences and 3.9 million tuned sound parameters*.
End user benefit
This increases listening comfort in all types of listening environments, even in situations where beamforming is active but noise is still present in front of the listener.

Directionality feature
Our binaural hearing strategy uses real time information about the user’s environment and stronger directional patterns to ensure smooth adjustments of directional settings.
May use M&RIE (Microphone & Receiver-In-Ear) or Spatial Sense for spatial cue preservation. Simply hear everything all around you, with the industry best at providing access to surrounding sound.1
This is the default program in many of our hearing aids and allows for automatic changing of directionality settings during use to one of the following three listening modes.
All frequencies get preserved by the different listening modes, allowing for a natural sound and brilliant listening experience – all without the patient lifting a finger.
End user benefit
Better hearing with less effort in all daily life situations.

Directionality feature
Forms an even stronger powerful directional pattern using the sound from both hearing aids so your patient can focus on the person in front of them.
With our 4-microphone bilateral beamformer, we allow for the true power of directionality to support the user in hearing what they want, while still keeping the auditory awareness of surrounding sounds. The binaural beamformer in Front Focus has a higher resolution than the legacy Ultra Focus, giving an astounding 150% improvement in speech recognition in noise.1
Our binaural beamformer uses a multiband approach to preserve spatial hearing cues. So, give your patients a great auditory experience while improving their speech understanding in noise, and read more about the inner works in our whitepaper.
End user benefit
Helps end users hear through the noise to enjoy the best one-to-one hearing experience.

Directionality feature
Your patients’ ears are like no others, and so is their listening experience. That is why we offer our unique M&RIE solution, allowing you, the hearing care professional, to give an easy fitting, with great benefits for the patient.
The M&RIE design has a third microphone that sits in the ear to collect sounds in the most natural way. It offers the most natural sound quality in a RIE (Receiver In Ear) hearing aid.
It is proven to reduce listening effort and eliminate wind disturbance. This results in 99% of users who trial the M&RIE receiver keep it after trial1.
End user benefit
M&RIE uses the unique shape of the ear to collect sound the way nature intended. Patients get the natural sound of custom products, combined with the advanced features and ease of use of a RIE model, for an immersive and individualised hearing experience with greater depth and direction.

Directionality feature
Forms a powerful directional pattern using the sound from both hearing aids so your patient can focus on the person in front of them.
Uses a powerful combined directional pattern from both hearing aids to focus on the person in front of your patients when they need extra help in very noisy environments.
It prioritizes sound from the side with the least noise to make the speech as clear as possible. While speech is made clearer, it can still help patients maintain spatial cues around them, by using the speech frequencies for the targeted directionality in front and the high and low frequencies to monitor the environment.
End user benefit
Great one-to-one hearing experience in the toughest environments. When the sound environment is most demanding, Ultra Focus lets patients hear and understand speech, to stay connected to others. The outcome is a renewed confidence in situations, which they might otherwise have avoided.
Directionality feature
Uses real time information about the user’s environment to automatically adjust the directional microphone patterns according to a binaural hearing strategy. May use M&RIE or Spatial Sense for spatial cue preservation.
The binaural beamformer maximizes SNR (Signal to Noise Ratio) and preserves spatial cues, and automatically adjusts directional microphone patterns to put patients in the best and most natural position to hear what is important and still monitor the sounds around them.
End user benefit
Puts patients in the best position to hear sounds naturally, for greater hearing in any environment. By allowing them to access more sounds than other hearing aids, it lets their brains classify what is important, not their hearing aids.
Signal Processing Feature
Our signal processing philosophy based on the natural cochlear frequency analysis. We were the first manufacturer to implement this analysis in our amplification strategy1, and it allows for natural sound and excellent fittings.
Maps the pitches into 17 smoothly overlapping frequency bands corresponding to the auditory Bark scale. The Bark scale incorporates the human auditory system’s critical bandwidth as the scale unit.
This allows for a smooth and fast-acting frequency response that enhances sound quality, minimizes distortion and creates a natural and clear sound picture for the hearing aid user.
End user benefit
Near-zero distortion and remarkable purity of sound.

Directionality feature
Spatial awareness and ability to localize sounds are important aspects of ensuring an organic listening experience with natural sound. The unaided ear is able to use the spatial cues to do this, but when using a hearing aid behind the ear and using wide dynamic range compression, these cues can be obstructed.
Two of the main spatial cues are Interaural Level Difference (ILD) and the pinna effect.
We use a combination of two algorithms to support these cues.
The first is a pinna restoration algorithm. It reproduces the monaural spectral cues of the open ear that are disrupted by positioning the hearing aid microphone outside of the pinna. The second algorithm preserves the ILD, which is the natural difference in the levels of sound reaching each ear that are caused by the head shadow. This is an important binaural localization cue that can be disrupted by Wide Dynamic Range Compression.
This provides more natural sound processing by restoring the auditory cues of the external ear and maintaining interaural level differences between the two ears. A vivid hearing experience your patient is in control of with a natural awareness of surroundings, speech, and sounds.
End user benefit
Vivid spatial awareness with exceptional sound quality.
Directionality feature
Automatically adjust beamwidth depending on the strength of the speech signal in front of the user. Users hear clear, focused sound from the front automatically optimized for the listening environment they are in.
End user benefit
Improves speech understanding in dynamic, noisy situations.
Directionality feature
Allows for adjustment of the frequency that blends between omnidirectional and directional processing. Personalize and enhance the experience of hearing speech and surroundings with a rich sound quality.
Prepares low and high pitches to be treated differently.
Directionality can be applied to high pitches, while low pitches always remain in omni.
End user benefit
Improved sound quality compared to full band directionality and preserved low frequency interaural timing differences (ITD), for improved localisation.
Feedback management feature
Reduces unwanted feedback in nearly any situation without compromising gain via phase cancellation with static and dynamic filters. Whistling noises, known as feedback, will not disturb listening experiences or alter the volume.
When feedback is detected, a phase-inverted signal is applied, which cancels out the whistling. It applies two individual control systems that work together to provide maximum comfort with feedback-free hearing.
The system analyzes the calibration signal during fitting and neutralizes feedback with a static control signal. This accounts for the unchanging contributors to feedback such as venting, ear geometry, and hearing aid components.
The dynamic control system includes two parts. One is a dynamic filter that changes to eliminate feedback via phase cancellation when wearing the hearing aids. As part of the dynamic control system, Whistle Control is used only in extreme cases, when DFS Ultra III alone cannot cancel feedback completely. In such cases, it lowers the gain to the prescribed level of frequencies affected by feedback until feedback is eliminated.
End user benefit
User is not bothered by feedback or by sudden reduction of volume, which some other hearing aids do to prevent feedback.
Noise Management feature
Reduces noise by spectral subtraction. It analyses the incoming sound and recognizes when speech is present within the individual bands. A spectral analysis is continuously carried out whenever speech is not present. This allows the noise spectrum to effectively be “subtracted” from the total signal without affecting speech.
The amount of noise subtracted is dependent on the setting and is weighted according to a speech importance function.
End user benefit
Improves listening comfort without compromising speech understanding.
Noise management feature
Detects and reduces wind noise without reducing gain for other sounds. Gives comfort in the great outdoors, so wind does not disturb the hearing experience.
This algorithm varies with the environment and the level of the wind noise, making the reduction personalized to the situation without sacrificing audibility for other sounds.
End user benefit
A natural sounding experience, with soft wind awareness in the background and minimal impact on audibility of other sounds in the environment.
Noise management feature
Quickly detects and reduces amplification for sudden, brief loud noises. Cushions the discomfort of sudden, loud sounds without affecting sounds of interest/focus sounds. Improves listening comfort and sound quality for impulse sounds like clanking silverware or jangling keys.
Impulse noise reduction works in parallel with the WDRC bands compression system to ensure that transient sounds are not over amplified. Soft transient speech sounds are preserved.
End user benefit
Improves listening comfort and sound quality for impulse sounds like clanking silverware or jangling keys.
Noise Management feature
The Environmental Optimizer II connects the Environmental Classifier to real life. This gives you, the hearing care professional, an easy tool to address users’ feedback and experiences, and the Environmental Classifier automatically recognizes the environments and changes the volume based on the settings in Environmental Optimizer II.
It also makes the process of fine tuning a breeze as with Environmental Optimizer II, the applied level of our NoiseTracker II noise reduction is also adjusted automatically.
You simply adjust sliders to fine tune how overall volume and Noise Tracker II should be applied in seven different environments. This expands your possibilities to help the hearing aid user hear speech, increase listening comfort, and enhance or suppress other types of sounds.
For Environmental Optimizer II, click on ‘Per Environment’ under ‘Noise Tracker II’ in the ‘Comfort’ tab and you are ready to help create a comfortable listening experience.
End user benefit
Users enjoy optimal audibility and listening comfort even when moving through rapidly changing sound environments, and without needing to make frequent manual adjustments.
Fitting & convenience feature
Help patients hear the higher tones of speech that would otherwise be missed due to the configuration of their hearing loss. Improves audibility of high-frequency sounds by compressing them to a lower frequency zone where they can be heard. The output is compressed within the compressed zone, so that the max output is within the audible level.
The different sound shifter settings regulate the knee point frequency (where the compression begins) and the compression ratio, with a stronger setting increasing these values.
End user benefit
Improves audibility of speech cues that would otherwise be lost while maintaining best possible sound quality.
Fitting & convenience feature
Optimizes loudness for users with severe and profound hearing losses. Boosts the listening experience with a louder, fuller sound quality when needed.
End-users with severe and profound hearing losses often prefer more low frequency gain than typically prescribed. This helps meet sound quality preferences without increasing risk of feedback.
Low Frequency Boost gives the fitter a quick and easy way to adjust the low frequency gains with three settings.
End user benefit
The hearing instrument provides the preferred sound quality.
Fitting & convenience feature
Switches automatically to a telephone program upon detection of a handset.
End user benefit
User can conveniently use the phone without needing to consider hearing aid programs.
Fitting & convenience feature
Provides fitting flexibility for experienced end-users with severe and profound hearing losses, many of whom have developed a preference for the sound to which they are already accustomed.
End user benefit
User can conveniently use the phone without needing to consider hearing aid programs.
Directionality feature
Automatic directionality that determines the best microphone configurations across two hearing aids based on the level and location of speech and noise around the user. Easily focus on the sound that interests you, while still being aware of any background noises.1
End user benefit
Better hearing with less effort.

Directionality feature
Automatic directionality that determines the best microphone configurations across two hearing aids based on the level and location of speech and noise around the user.
Caters to the way sound is processed in the brain. It also includes Spatial Sense for more natural sound processing. Listen effortlessly and clearly in all situations, wherever speech or sounds are coming from.
Relies on Ear-to-Ear data exchange to select the optimal microphone mode on each ear so the strongest voice signal is clear without losing the ability to perceive the surroundings and other speakers.
End user benefit
Better hearing with less effort.
Directionality feature
Provides a non-varying hypercardioid pattern to reduce noise coming from behind and the sides of the user. Ideal for moments of concentration on a sound or a person in front.
Fixed Directionality is the simplest directional option. In this setting, signals coming from behind and the sides are reduced to enable the user to better concentrate on signal from the front. The directional characteristics are constant and static. If selected, this type of directionality is always ‘on’.
End user benefit
Improves speech understanding in dynamic, noisy situations.
