Comparison of BC-ABR threshold category to AC behavioural threshold data for 2000 Hz (a) and 500 Hz (b). Filled circles indicate ears with “certain” hearing status, whereas open circles indicate ears with “presumed SNHL.” Filled triangles represent ears where BC behavioural results were used (i.e., when AC behavioural results did not reflect cochlear status). Behavioural categories are indicated by horizontal lines/shading. See text for details.
