SELF-ESTIMATED AND MEASURED INTELLIGIBILI TY OF AUDIOMETRIC SPEECH MATERIAL

Self-estimated and measured intelligibility were compared using differ ent instructions in speech audiometric tests. The results of 69 tested persons reveal that there exist speech levels in both test procedures where the intelligibility reaches 0% or 100%, respectively. In genera l, self-estimated intelligibility was significantly higher than real i dentification. Therefore, the self-estimation of intelligibility does not appear as an appropriate procedure to automated speech audiometry. The results are a speech audiometric equivalent of the subject's to h ave correctly understood speech in daily life in which in fact was mis understood. Connections to central speech processing seem to be possib le. Audiologists might be influenced by the effect of overestimation o f speech intelligibility as well. However, preliminary investigations concerning pseudohypacusis show different results.
