Abstract
Intelligibility functions of word lists and a sample of continuous discourse distorted by several levels of low-pass filtering demonstrate the effect of word familiarity when normal-hearing subjects are listening to distorted speech. Lists of varying degrees of familiarity compiled by Owens (1961), PB-50 lists 6 and 9, W-22 list 1-A, and a sample of continuous discourse are compared. Errors increased as distortion increased for the lists falling in the “unfamiliar” category, while intelligibility remained undisturbed in the continuous discourse and in the “familiar” lists as long as frequencies below 1560 Hz were left intact.
