AX Technology

Signia AX has two sound processors – one to focus on speech which will sound crisper and clearer, whilst environmental and background noises are kept in the background.

Advanced sensor technology recognises if you are moving, and detects which hearing situation you are in automatically, to ensure that you always experience the best possible sound as you move through your day.

Hearing aid wearers who have already experienced this revolutionary technology confirm its benefits: a full 100% of participants in a recent study reported excellent speech understanding in their home environment.²

They also enjoyed more than 25% better speech understanding in noise than with their previous hearing aids.²

The AX platform is even proven to perform better than normal hearing in a tested party scenario.³
