Digit recognition was measured in quiet and in two noise conditions by English-native (EN) and Chinese-native (CN) listeners. EN listeners were tested using English digits and CN listeners were tested using both English and Chinese digits. In quiet, forward digit span recall worsened for both groups as the number of digits was increased. Significant effects of language experience were observed with five or more digits. Language experience had a significant effect on digit recognition in babble but not in steady noise. These results suggest that understanding of a nonnative language can be influenced by both cognitive load and listening environment.
以英语为母语（EN）和以中文为母语（CN）的听众在安静环境以及两种噪声条件下进行了数字识别测试。使用英语数字对EN听众进行测试，使用英语和中文数字对CN听众进行测试。在安静环境中，随着数字数量的增加，两组的顺向数字广度回忆都变差。在有五个或更多数字时观察到了语言经验的显著影响。语言经验在嘈杂环境中对数字识别有显著影响，但在稳定噪声环境中则没有。这些结果表明，对非母语的理解可能会受到认知负荷和听力环境的影响。
