Audiology technology leader Signia is redefining the art of hearing through binaural beamforming as enabled by wireless full-audio transmission between a bilateral pair of hearing aids. Signia Narrow Directionality is even clinically proven to outperform natural hearing in demanding situations*. Far from limiting the wearer, directionality is an absolute necessity in maintaining speech understanding in challenging listening environments. Our smart devices filter out the background noise so that life sounds brilliant.

Narrow Directionality remains the only solution in the industry that is proven to offer better than normal hearing performance in such situations.* Just how much of a difference the industry’s most advanced directional technology delivers compared to conventional solutions is illustrated in these short tongue-in-cheek videos:

Hear better. Live safer.

Signia boosts natural hearing

The leading edge primax hearing aid technology supports the way we hear naturally in all listening environments, from quiet surroundings to very noisy situations. The sophisticated solution applies directionality automatically and only when the wearer needs it, in the same way that healthy ears hone in on a specific sound source in a noisy environment. In this way, primax supports the natural behavior of listeners by offering the ability to focus on what’s important.



In quiet surroundings, wearers want to enjoy all natural soft sounds to the fullest, such as birdsong or a gentle breeze rustling through the trees.

primax supports this by providing the right amount of amplification. TruEar simulates the directivity of the outer ear to provide a natural listening experience. The wearer is able to hear from all around while the localization of sounds is maximized.


Speech in quiet surroundings

These are typically situations where the wearer is talking with one or two other people at home, in a park or in another quiet environment.

primax supports this with the right amplification and the simulation of the natural directivity of the outer ear via TruEar. Since the wearer is able to hear from all around, it is easy to localize where different sounds are coming from.


Speech in noisy environments

These are situations where the wearer communicates with someone in a louder environment. Louder environments include ambient sounds like music, noises or other people talking. In such an environment, we usually face our conversation partner directly and may even move closer to them in order to understand them better.

primax supports this natural behavior by applying directionality. The strength of the directionality depends on the overall noisiness and complexity of the situation. In these situations, we naturally make sure that we are facing our conversation partner. Directionality supports this by attenuating sounds from the sides and behind. In addition, because the speaker of interest is within our field of vision in such situations, localization becomes less important as priority is increasingly placed on speech intelligibility.



Speech in very loud situations

Imagine trying to talk to a friend in a crowded bar or at a busy railway station. You can still hear and understand, but you need to concentrate. In these situations, listening requires a lot of effort because the background noise is as loud as, or louder than what we are trying to listen to. In a crowded place, we talk very closely to our conversation partner and we raise our voice to be heard.

primax Narrow Directionality is engaged only in these situations to help the wearer hear and understand the speaker directly in front while sounds from all other directions are attenuated. Speech intelligibility is the primary listening goal. Localization becomes virtually irrelevant since in such situations, even if a speaker comes up from behind, the speaker would naturally try to get the attention of the listener first by a tap on the shoulder or getting into the listener’s field of vision. In these very difficult listening situations, primax outperforms all other hearing aids and has even been clinically proven to outperform normal hearing.*

FAQs - Directional hearing

* En undersøgelse foretaget på University of Northern Colorado i 2015 undersøgte effektiviteten af de nye primax-funktioner ved at samle og analysere løbende EEG-data, mens testpersoner udførte taleprøver. For begge primax funktionerne, SPEECH og EchoShield, viste objektive målinger af hjernefunktionen et signifikant fald i anstrengelsen ved at lytte, når funktionen blev aktiveret.
