Effekten av frekvenskomprimerande hörapparater på taluppfattningen hos patienter med grava diskantnedsättningar – En experimentell studie
The effect of frequency compressing hearing aids on the speech perception of patients with severe to profound hearing losses in the high frequency regions – An experimental study
A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p≤0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated. All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study.
