Abstract: Speech understanding in noisy environments has been the most desiredhearing-aid (HA) benefit sought by HA users. This paper examines thepossibility of developing a speech-related HA benefit index from the speech-related questions in the self-reported questionnaire data. One question fromHealth-Related Quality of Life (HRQoL) instrument 15D and nine questionsfrom the Speech, Spatial and Qualities of Hearing Scale (SSQ) having adirect implication to speech were selected for the analysis. After applyingweights relevant to 15D, a delta of base-line (prior to HA fitting) and follow-up (two months after the initial fitting) responses to the selected questionswere determined. A principal component analysis (PCA) was performedon the scaled and centered delta values. The resultant principal componentscores were used to derive the composite index indicative of speech-relatedHA benefit.
