PURPOSE: to research and compare the speech recognition of 7 to 10 years-old normal-hearing scholars from different socioeconomic-cultural levels, through a test that uses sentences as stimulus (silence and competitive noise). METHOD: 51 children, from seven to ten years and 11 months, divided into two groups according to the socioeconomic-cultural level participated of the study. Thus, the Group 1 (G1) - middle high level - was comprised of 23 children and the Group 2 (G2) - middle lower level - of 28 children. Realized procedures: anamnesis; meatoscopy; to obtain hearing thresholds, measures of acoustic impedance and Recognition Sentence in the Silence Thresholds (RSST) and in the Noise (RSNT), expressed by the signal/noise ratio (S/N). These Recognition Sentence Thresholds were obtained using the Portuguese Sentence Lists test (PSL). The data were statistically analyzed. RESULTS: there was no statistically significant difference between right and left ears for the analyzed variables in both groups. The average for the RSST for the G1 was 9.3 dB HL and for the G2, 10.7 dB HL. The S/N average in the G1 was -5.9 dB HL and in the G2, -1.7 dB HL. Statistical analysis showed significant difference between groups only for the S/N. CONCLUSIONS: when the auditory processing is more required, the middle lower level children demonstrated reduced performance, comparing to the upper middle level children.
