This study concems subjective intelligibility rated with method of magnitude estimation . Rating tests were conducted for speech sound and monosyllable sound in steady broad ・ band noise at various levels . Relation of subjective intelligibility ratings between speech sound and monosyllable sound was i【1vestigated in relation to SIN ratios . Correlation of subjective intelligibility ratings to SfN ratios and standard errors of estimate were also calculated , As the results , subjective intel ・

Subjective intelligibility of speech sound could be estimated at 3. 3dB ( PSE ) lower than subjective intelligibi1 − ity of monosyllable sound which cQuld be predicted by articulation index. 1. は し が き
