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.
