Purpose of the present study is to evaluate the effects of aging on temporal resolution and speech understanding in noise.
Twenty-seven young and 33 older normal hearing adults participated in this study. Temporal resolution was investigated using the Gaps in Noise (GIN) test. Understanding sentences in noise was investigated using a Dutch sentences (LIST) test.
Results demonstrated that older adults have significantly worse temporal resolution scores and significantly greater difficulty understanding sentences in noise than younger adults. In the group of older adults, the ability to understand sentences in noise correlated with hearing and age. A stepwise regression analysis showed that age was the best predictor for the speech in noise results. However, temporal resolution correlated with hearing, not with age. Results from the GIN test did not correlate with the results from the LIST test.
The present study shows that with advancing age, both temporal resolution and speech understanding in noise significantly diminish. Temporal resolution correlates with hearing, not age, while speech understanding correlates more with age than hearing. These results could have implications for the outcome of auditory prostheses in older adults, as both diminished temporal resolution and speech understanding have to be taken into account.
本研究旨在评估衰老对时间分辨率以及噪声环境下言语理解能力的影响。
27名年轻和33名年长的听力正常成年人参与了本研究。使用噪声间隙（GIN）测试来研究时间分辨率。使用荷兰语句子（LIST）测试来研究噪声环境下的句子理解能力。
结果表明，与年轻成年人相比，年长成年人的时间分辨率得分显著更差，并且在噪声环境下理解句子的难度显著更大。在年长成年人组中，噪声环境下理解句子的能力与听力和年龄相关。逐步回归分析表明，年龄是噪声环境下言语结果的最佳预测因素。然而，时间分辨率与听力相关，而非与年龄相关。GIN测试的结果与LIST测试的结果不相关。
本研究表明，随着年龄的增长，时间分辨率和噪声环境下的言语理解能力均显著下降。时间分辨率与听力相关，而非与年龄相关，而言语理解与年龄的相关性比与听力的相关性更强。这些结果可能对老年成年人听觉假体的效果产生影响，因为必须同时考虑时间分辨率和言语理解能力的下降。
