With the inclusion criteria applied, the resulting sample was of 1,642 test results, which were divided into eight groups according to age and two groups regarding sex, in order to perform the necessary analysis.
Results: It was found a worsening in speech recognition in quiet with advancing age. In the comparison between the sexes, the analysis of the speech recognition index for monosyllabic words revealed statistically superior average performance for women in the left ear. Moreover, in both the testing of monosyllabic and dissyllabic words, women had results that showed better performance in the left ear compared to right ear, which is a significant result from the statistical standpoint compared to men.
Conclusion: Age and sex showed up as factors that influence performance in speech recognition. The more advanced the age, the worse is the performance of the individual in the test. Women presented results that have revealed better performance than men.
