Scatterplots of average fusion ranges obtained using the 5AFC procedure versus various subject-specific parameters, including first principal component (PC1) and second principal component (PC2), in HI listeners. (A) Fusion range versus duration of hearing loss. (B) Fusion range versus duration of HA use. (C) Fusion range versus subject age. (D) Fusion range versus age of onset of hearing loss. (E) Fusion range versus PC1, a weighted sum mainly of factors in (A)–(D). (F) Fusion range versus PC2, weighted mainly by daily hours of HA use. (G) Fusion range versus average real-ear levels in the reference ear. (H) Fusion range versus average real-ear levels in the reference ear, adjusted for PC1. “*” indicates significant p-values (p < 0.05); p-values are only shown for adjusted, not crude, correlation analyses in (E), (F), and (H).
