PURPOSE: to investigate the equivalence among of sentence lists of the test: Lists of Sentences, in Portuguese, proposed by Costa in 1998. METHODS: the information was taken from a database of a research project. 240 individuals with at least complete high-school, 18 to 30-year old and having normal audibility thresholds, were studied. The Sentence Recognition Thresholds under Silence and under Noise were separately searched in each ear through earphones. In The Sentence Recognition Thresholds under the Noise, speech and noise were presented at the same ear. RESULTS: comparing the results among the lists, we find average difference of 0.03 dB NA to 0.86 dB NA under silence and 0.04 dB NA to 1.06 dB NA under noise. The minimum and maximum values in the six lists were very close. CONCLUSION: it was observed that in the application of the test Lists of Sentences in Portuguese, through earphones, both under silence as well as under noise, similar results were obtained in the lists 1B, 2B, 3B, 4B, 5B and 6B, showing equivalence among the lists.
