Maintaining Narrow Directionality While Improving Soundscape Processing

Since its introduction with the binax platform in 2014, Signia’s Narrow Directionality has been the industry leader in optimizing speech understanding in background noise. The purpose of the current research was to ensure that the Narrow Directionality feature of the Xperience was equal to that of the Nx model—previous research has shown that the speech-in-noise processing of the Nx is superior to that of premier models from competitive manufacturers. Indeed, the results of this research revealed that there was no difference in the speech recognition findings for the two different instruments. This allows us to reasonably assume that Xperience also is superior to the competition for these important listening conditions. For those who were questioning if it is possible to obtain excellent soundscape processing for speech, while still maintaining a high level of narrow directionality, the answer is yes.

Closing the Open Fitting: An Effective Method to Optimize Speech Understanding

The findings of this research clearly show that the coupling system chosen by the HCP can have a substantial effect on subsequent speech understanding in background noise for the patient. The mean additional signal-to-noise ratio (SNR) benefit for a closed fitting was 3 dB, which corresponds to an impressive improvement in speech understanding of approximately 50%. This constitutes a significant advantage for the patient’s daily life in terms of social interaction. This benefit should not easily be foregone, especially in light of the clinically proven high acceptance of closed fittings based on the patient’s improved perception of his or her own voice as a result of Signia Own Voice Processing.

Moving Beyond the Audiogram Towards a Patient-Centered, Interactive First Fit

It has long been known that pure tone audiogram (PTA) measurements cannot fully account for the variation in speech intelligibility scores measured from hearing impaired listeners. With regard to hearing aid fittings, it is clear that there is no simple solution that would allow us to perform a consistently perfect customized fitting by even adding one additional variable to audiogram data. A transition from the “average” patient fitting towards a more individual fitting requires several stages. In this paper, these stages are described and explained, based on data obtained from several clinical studies.

Objective Measurement of Listening Effort

Listening Effort is the mental exertion listeners experience trying to solve an auditory task such as understanding speech (or detecting a target among interferers). Because listening effort is influenced by the clarity of the signal, it is therefore affected by hearing loss, as well as signal degradation caused by background noise or bad sound quality.

Reducing Listening Effort via primax Hearing Technology

The primary goal of amplification is improving speech understanding. When listening situations become noisier or more challenging, this is even more important. However, beyond improving speech intelligibility, another indicator of the effectiveness of hearing aid fittings that has sometimes been overlooked is the cognitive demands, or listening effort required for speech understanding to take place. This is why it is important to not only improve speech understanding, but also make speech understanding easy. This is the underlying goal of the new Signia primax™ platform ― to improve speech intelligibility and reduce listening effort for the wearer.
