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

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

Signia boosts natural hearing.

Leading edge primax™ hearing aid technology supports the way we hear naturally in all listening environments, from quiet surroundings to very noisy situations. Our 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 sounds coming from all around them while the localization of sounds is maximized.


Speech in quiet surroundings.

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

primax supports these conversations with the right amplification and 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 in which the wearer communicates with someone in a louder environment, such as those with ambient sounds (like music), noises, or other people talking. In such an environment we usually face our conversation partner directly, or might even move closer to them in order to understand better.

primax supports this natural behavior by applying directionality, the strength of which depends on the overall noisiness and complexity of the situation. Directionality attenuates sounds from the sides and behind. In addition, because the speaker of interest is within our field of vision, localization becomes less important and priority is increasingly devoted to 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 raise our voice to be heard.

primax Narrow Directionality only engages in these situations to help the wearer hear and understand the speaker directly in front of them, while sounds from all other directions are attenuated. Speech intelligibility is the primary listening goal. Localization becomes virtually irrelevant in these situations, because even if a speaker comes up from behind, they would naturally try to get the listener’s attention by first tapping them on the shoulder or moving into their 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.

* Study conducted at the University of Northern Colorado, 2015, examined the effectiveness of the new features of primax by collecting and analyzing ongoing EEG data while subjects performed speech testing. For both primax features SPEECH and EchoShield, the objective brain behavior measures revealed a significant reduction in listening effort when the feature was activated.
