Comparing the performance of the Widex SENSO digital hearing aid with analog hearing aids.

Differences in performance were evaluated between the Widex SENSO and several analog hearing aids currently worn by 50 hearing-impaired subjects. Subjects were initially fit with the SENSO using the manufacturer's recommended procedure. After wearing the hearing aids for 1 week, the adjustable parameters were fine-tuned based on subjective comments. Differences in performance between the SENSO and the subjects' current hearing aids were assessed using the Speech Perception in Noise administered at overall levels of 50, 65, and 80 dB SPL; the Hearing in Noise Test in which the background noise was presented at 50, 65, and 80 dBA; the Abbreviated Profile of Hearing Aid Benefit; and two questionnaires relating to overall preference between the SENSO and the subjects' current hearing aids.
