The relationship of continuous (C) and interrupted (I) tones at threshold and most comfortable loudness (MCL) in hearing-impaired ears.

Differences in the Bekesy tracking levels of continuous (C) and interrupted (I) tones at both threshold and most comfortable loudness (MCL) were determined in a large clinical sample of persons with hearing loss. Results indicate small but significant C-I differences not only at the two levels separately but also in the tracking of C and I tones at threshold relative to MCL, regardless of frequency or hearing loss severity. Such results may have implications for both diagnostic and rehabilitative audiology.
