The own voice issue, an unnatural sound.

As hearing care professionals, we strive to provide hearing aid users with sound quality that replicates what nature intended. Overall audibility and a natural sounding own voice are essential for first fit acceptance. Yet many hearing aid wearers do not like the sound of their own voice.

Every hearing aid wearer experiences a change in the sound of their own voice. Especially first time users and wearers with a mild or moderate hearing loss struggle with this perceived occlusion effect. Any such negative perception heavily affects acceptance and often leads to the rejection of hearing aids.

OVP Issue

In an attempt to resolve the own voice issue, hearing care professionals can reduce gain and open the venting, reducing audibility and speech understanding in noise. Whatever they do, the result is a compromise between sound quality and overall audibility.

Until today, this widely acknowledged problem has been considered unresolvable.

Signia Nx with OVP™ for the most natural own voice
and highest acceptance.


Signia Nx, the world’s most advanced hearing aid platform, provides the first genuine solution to the own voice issue. It delivers unsurpassed first fit acceptance by combining uncompromised audibility with a natural sounding own voice.

Own Voice Processing (OVP)

The world’s first Own Voice Processing (OVPTM) improves spontaneous acceptance of own voice by 80% of dissatisfied hearing aid wearers.* The revolutionary natural-sounding own voice provided by Signia Nx is based on its leading Ultra HDe2e binaural link. Its continuous full-bandwidth audio exchange enables dynamic scanning and processing of the wearer’s own voice completely independently from all other sounds, including all other voices.

This allows hearing care professionals to fine-tune the hearing aids for optimal audibility of the entire acoustic environment without having to compromise this audibility to improve the sound quality of the wearer’s own voice.

In this way, Signia Nx with OVP™ benefits all hearing aid wearers. It replicates the natural hearing experience to deliver the highest sound quality and releases the hearing aid’s full potential for best hearing performance in any situation, even in very noisy environments.

The world’s first natural own voice,
based on the leading binaural link.

The revolutionary natural experience of Signia Nx is only possible by processing the sound of the hearing aid wearer’s own voice completely independently from all other voices and sounds.

The Key to OVP™ is our upgraded continuous full-bandwidth binaural link, Ultra HD e2e. It now also powers beam-forming technology to create a precise scanning beam that identifies the individual sound path of the wearer’s voice as it travels to the hearing aids. This level of precision is only possible with the new fully integrated silicon microphone network.


Ultra HDe2e enables instantaneous and continuous dynamic own voice detection and patented dual processing of the own voice and the remaining soundscape. Signia Nx thereby provides the most natural own voice as well as the best speech understanding in noise.

Advance Soundscape Processing

The most advanced soundscape processing in the industry,
superior speech understanding in noise.

Beyond the wearer’s experience of a natural own voice, Ultra HD e2e also powers binaural beam-forming technology to provide clear speech understanding and a natural experience in all situations, even the loudest.

New algorithms enable the most precise spatial awareness. Hearing aid wearers can now get an uncompromised spatially open experience with all the benefits of our directionality.

For crystal clear sound, our extended dynamic range with an incredible 113dB maximum input delivers excellent signal quality in loud environments. And the powerful new feedback canceller provides the highest stable gain to protect signal quality – artifact-free.

The whole system is steered by Signia’s unique classifier which ensures OVP™ and soundscape processing work in perfect harmony to replicate the experience of natural hearing.


Superior hearing plus Bluetooth, a unique combination in the industry.

Today’s hearing aid wearers expect the highest hearing performance and seamless connectivity to help them hear in a modern world. Only Signia hearing aids combine the most advanced connectivity technologies to deliver a natural-sounding own voice and uncompromised audibility with direct streaming. Signia Nx offers the only wireless system combining Bluetooth and Ultra HD e2e thanks to its high energy efficiency.

Ultra HD e2e enables multiple unique audiological features. It is the continuous full-bandwidth binaural link that delivers the most natural hearing experience and sets Signia Nx apart from other manufacturers’ basic e2e wireless systems. Only Ultra HD e2e allows us to deliver our patented OVP™ and “better than normal hearing”.**

Our 2.4 GHz Bluetooth technology delivers the highest quality audio streaming from smartphones and TV. And our advanced laser edge antenna enables the smallest sized hearing aid with this special combination of wireless technologies.


Signia TeleCare, revolutionary remote hearing care.

Hearing care professionals strive to find the best fitting and fine-tuning for their patients. Finding the optimal settings in the controlled environment of a practice is one thing – but how to ensure that patients benefit from the most natural hearing experience in their daily lives?

Signia TeleCare keeps hearing aid trials on track and drives the conversion of patients with hearing loss to satisfied customers.

The new TeleCare 3.0 introduces full live remote tuning so professionals can fine-tune patients’ hearing aids in the real-life situations for which they are intended. They thus benefit from instant feedback to improve the fitting on the spot, much like a virtual home visit.

In combination with its unique guided assistance and communication via CareChat, TeleCare 3.0 saves time for hearing care professionals and their patients and raises the quality of care.

* 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.

**Two clinical studies have shown that binax provides better than normal hearing in certain demanding environments (University of Northern Colorado, 2014; Oldenburg Hörzentrum, 2013): Speech Reception Thresholds (SRT) in cocktail-party situations improved up to 2.9 dB for wearers with mild to moderate hearing loss using Carat binax or Pure binax hearing aids with narrow directionality, compared to people with normal hearing.
