Objective: This study provides descriptive statistics of the Danish reading span (RS) test for hearing-impaired adults. The combined effectof hearing loss, RS score, and age on speech-in-noise performance in different spatial settings was evaluated in a subset of participants.Design: Data from published and unpublished studies were re-analysed. Data regarding speech-in-noise performance with co-located orspatially separated sound sources were available for a subset of participants. Study sample: RS scores from 283 hearing-impairedparticipants were extracted from past studies, and 239 of these participants had completed a speech-in-noise test. Results: RS scores(mean¼41.91%, standard deviation¼11.29%) were related to age (p50.01), but not pure-tone average (PTA) (p¼0.29). Speech-in-noiseperformance for co-located sound sources was related to PTA and RS score (both p50.01, adjusted R-squared¼0.226). Performance forspatially separated sounds was related to PTA (p50.01, adjusted R-squared¼0.10) but not RS score (p¼0.484). We found no differencesbetween the standardized coefficients of the two regression models. Conclusions: The distribution of RS scores indicated a high testdifficulty. We found that age should be controlled when RS scores are compared across populations. The experimental setup of the speechin-noise test may influence the relationship between performance and RS score.
