(A) Profile of the dominance region expressed as d^′_e as a function of harmonic number. d^′_e represents the difference between Primarylike and Chopper groups (see text for details). (B) Black-filled bars show the distribution of harmonics, which resulted in a d^′_e⩾1 from the functions in (A). Gray-filled bars and striped bars show the distributions obtained from a similar analysis for chinchillas (data from Shofner and Yost, 1997) and normal hearing human listeners [data from Leek and Summers (2001)], respectively.
