【 摘 要 】

INTRODUCTION: Tests of sentences recognition in quiet still are neither very used in the clinical audiological routine and nor in researches. That's why, many times, when this evaluation is accomplished, the clinicians doesn't possess parameters to interpret or classify the results.AIM: Thus, the aim of this study was to investigate the correlation between the sentences recognition threshold in quiet (SRTs) and the average of the tonal thresholds in the frequencies of 0,5, 1 and 2 kHz.METHODS: 200 ears of normal-hearing individuals, 50 men and 50 women (average 34,61 years) were examined. First, an anamnesis, meatuscopy, pure tone audiometry, speech recognition threshold and speech recognition percent index were done. After that, by using the Portuguese Sentences Lists Test, the research of sentences recognition threshold in quiet (SRTs) took place.RESULTS: The medium SRTs obtained in the 200 examined ears was 6,15 dBHL and the average of the tonal thresholds for the frequencies 0,5, 1 and 2 kHz was 8,55 dBHL. The statistical analysis revealed significant correlation between the variables studied.CONCLUSIONS: The average of the tonal thresholds in the frequencies of 0,5, 1 and 2 kHz can be used as reference for the analysis of the results obtained in the research of SRTs. Besides, it can be expected that the values of SRTs are better than the values obtained with the average of the tonal thresholds, because the sentences supply acoustic and linguistic tracks with meaning.
