Resumo: |
Introduction: The auditory temporal resolution ability is responsible for the identification of silence gaps in function of time, allowing the perception of the occurrence of one or two stimuli. This auditory ability disorders are frequently associated with difficulties in phonological processing and in auditory discrimination of temporal cues in speech. Studies report that elderly subjects need a bigger gap to identify the presence of two tones and this would explain some of the complaints about the speech comprehension of this population. Objective: To measure the temporal resolution threshold in elderly people through the Random Gap Detection Test Expanded (RGDT-E), developed by Keith (2002), and to verify the correlation between the RGDT results for the variables gender, age, audiometric threshold and punctuation in the Self-Assessment of Communication questionnaire (SAC). Methodology: We evaluated 63 subjects of both genders with normal peripheral hearing or symmetric mild sensorineural hearing loss. Results: A better performance was observed, in milliseconds (ms), of the male gender group in all evaluated frequencies, where the RGDT results average is between 500 and 4000 Hz frequencies, for the female gender of 104,81 ms (DP+- 48,8 ms), and for the male gender of 22,08 ms (DP+- 20,15). Regarding the SAC results, most part of the evaluated people (62:63) didn't present significant complaints of communication difficulty (SAC of level 1 or 2), where in the male gender group any subject (0:10) presented significant complaints of communication difficulty, and in the female gender group, only 1:53 presented complaints (SAC of level 3). The results for the SAC in percentage were also similar in both groups, with an average of 9,95% (DP+- 12,28%) for the women group and of 7,78% (DP+- 7,12) for the men group. When the SAC questionnaire was compared with the RGDT, it was observed that between the male gender subjects only one subject, among 10 evaluated, presented temporal resolution threshold bigger than 20ms and also presented SAC of level 1. On the other hand, in the female gender group, 50 women, among 53 evaluated, presented medium results for the RDGT bigger than 20ms; however, only one presented significant complaint of communication difficulty (SAC of level 3). In the statistic analysis of the variable gender over the variables RGDT and SAC, it was observed that both genders are statistically different only on the RGDT results. On the other hand, it wasn't observed significant statistically differences between the genders for the SAC. Concerning the age and the audiometric configuration, significant statistically differences weren't observed for the RGDT variables or for the SAC. Conclusion: Comparing the RGDT results with the reference values for young population, the age presented to be a complicate factor of the temporal resolution thresholds, mainly for the female gender; however, even with increased thresholds, this population doesn't mention communication difficulties |
