 The Speech Intelligibility Rating Test (SIR Test) |
|
 |
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 facsimile of a suitable rating
scale is included with this compact disc. |
