Description:  

The SIR Test uses subjective estimations of the proportion of words understood to quantify the intelligibility of continuous speech. The user is encouraged to consult Cox and McDaniel (1989) and McDaniel and Cox (1992) about the development and administration of the test and reliability and sensitivity of data from normal-hearing and hearing-impaired listeners. Briefly, in this test, listeners rate the intelligibility of test passages on an equal-appearing interval scale from 0 to 100. A rating of 0 should reflect a situation in which none of the words is understood and a score of 100 would represent a situation in which all of the words are understood. A copy of a suitable rating scale is included with this compact disc.
