Boosting real-world listening performance with Signia AX: A first glimpse at data from an international survey

To test the wearers’ experience of Signia AX in real-world listening situations, an international survey was done in which respondents were fitted with Signia AX devices and then assessed the devices in their everyday life and compared the performance to that provided by their own hearing aids. In this white paper, we present preliminary data from the US part of the survey. The data indicate high levels of satisfaction with AX in a variety of listening situations and a clear preference for AX over the respondents’ own hearing aids.

Performance of Signia AX in at-home listening situations

Due to the restrictions dictated by the COVID-19 pandemic, a fully remote study of Signia AX was done in collaboration with Hörzentrum Oldenburg in Germany, involving both fitting and assessment of Signia AX being done in the participants’ own homes. The results showed high levels of immediate satisfaction with AX just after the fitting, and in an at-home speech-in-noise test, the new Augmented Focus processing allowed the participants to perform significantly better with AX than with their own hearing aids.

Improving speech understanding with Signia AX and Augmented Focus™

In a study at the University of Northern Colorado, the performance of Signia AX was tested in challenging communication situations simulated in the lab. The results showed that activation of the new Augmented Focus processing significantly improved the participants’ ability to understand speech in a restaurant scenario. Furthermore, the speech-understanding performance exceeded that offered by two main competitors and was on par with the performance of a normal-hearing reference group. In a simulated party scenario, the performance with AX was even better than normal-hearing performance when binaural beamforming was activated.
