Closing the Open Fitting: An Effective Method to Optimize Speech Understanding
Matthias Fröhlich, Veronika Littmann
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.
