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. Any such negative perception heavily affects acceptance and often leads to the rejection of hearing aids. 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.
The world’s first natural own voice
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. The world’s first Own Voice Processing (OVPTM) improves spontaneous acceptance of own voice by 75% of dissatisfied hearing aid wearers.*
The key to OVP is our 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 (soundscape processing). 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.
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 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.
Ultra HD e2e plus Bluetooth – a unique combination in the industry
In addition to the world’s first natural own voice, Signia Nx offers the only wireless system combining Ultra HD e2e and Bluetooth for uncompromised audiology and direct streaming in one device. Only Ultra HD e2e can deliver our patented OVP and “better than normal hearing”** while 2.4 GHz Bluetooth technology delivers the highest quality direct audio streaming from iPhone and TV.
Signia TeleCare – revolutionary remote hearing care
A further big advantage of Signia Nx is TeleCare – now with full live remote tuning after the personal first fitting so hearing care professionals can fine-tune patients’ hearing aids in the real-life situations for which they are intended. Much like a virtual home visit, this enables hearing care professionals to deliver revolutionary customer care by solving issues remotely to keep the trial on track.
