摘要
目的分析调制掩蔽（BMM）对青年、成年和老年正常听力者听力的益处。方法对60名年龄在18-75岁之间的正常听力者进行行为评估（在稳定噪声和调制噪声下的句子识别测试）和电生理评估（皮层听觉诱发电位），以研究BMM。采用配对 t 检验和重复测量方差分析对结果进行比较分析，然后进行 Bonferroni 事后检验（p 值为 0.05）。与稳定噪声相比，调制噪声能产生更好的听觉阈值反应（电生理学和行为学）。结论可以得出结论，调制噪声对所有参与者的神经反应幅度（较小的延迟）和神经处理时间（较大的振幅）产生的干扰较小。老年组的听觉阈值（电生理学和行为学）较高，BMM幅度较低，即使在噪声调制的情况下也是如此，这表明老年人群的时间听觉能力较低，可能与衰老过程有关，表明他们的时间分辨能力存在缺陷。
Benefit of Modulated Masking in hearing according to age
Objective
To analyze the Benefit of Modulated Masking (BMM) on hearing in young, adult and elderly normal-hearing individuals.
Methods
The sample included 60 normal-hearing individuals aged 18–75 years who underwent behavioral assessment (sentence recognition test in the presence of steady and modulated noise) and electrophysiological assessment (cortical Auditory Evoked Potential) to investigate BMM. The results were analyzed comparatively using the paired t-test and ANOVA for repeated measures, followed by the Bonferroni post-hoc test (p-value < 0.05).
Results
A decrease in latencies and an increase in amplitudes of cortical components (P1-N1-P2) was observed due to noise modulation in all age groups. Modulated noise generated better auditory threshold responses (electrophysiological and behavioral), compared to steady noise. The elderly presented a higher threshold in both hearing domains, compared to the other participants, as well as a lower BMM magnitude.
Conclusion
It was possible to conclude that the modulated noise generated less interference in the magnitude of the neural response (smaller latencies) and in the neural processing time (larger amplitudes) for the speech stimulus in all participants. The higher auditory thresholds (electrophysiological and behavioral) and the lower BMM magnitude observed in the elderly group, even in the face of noise modulation, suggest a lower temporal auditory performance in this population, and may indicate a deficit in the temporal resolution capacity, associated with the process of aging.
期刊介绍：
Brazilian Journal of Otorhinolaryngology publishes original contributions in otolaryngology and the associated areas (cranio-maxillo-facial surgery and phoniatrics). The aim of this journal is the national and international divulgation of the scientific production interesting to the otolaryngology, as well as the discussion, in editorials, of subjects of scientific, academic and professional relevance.
The Brazilian Journal of Otorhinolaryngology is born from the Revista Brasileira de Otorrinolaringologia, of which it is the English version, created and indexed by MEDLINE in 2005. It is the official scientific publication of the Brazilian Association of Otolaryngology and Cervicofacial Surgery. Its abbreviated title is Braz J Otorhinolaryngol., which should be used in bibliographies, footnotes and bibliographical references and strips.
