The abilities of 59 adult hearing-aid users to hear phonetic details were assessed by measuring their abilities to identify syllable constituents in quiet and in differing levels of noise (12-talker babble) while wearing their aids. The set of sounds consisted of 109 frequently occurring syllable constituents (45 onsets, 28 nuclei, and 36 codas) spoken in varied phonetic contexts by eight talkers. In nominal quiet, a speech-to-noise ratio (SNR) of 40 dB, scores of individual listeners ranged from about 23% to 85% correct. Averaged over the range of SNRs commonly encountered in noisy situations, scores of individual listeners ranged from about 10% to 71% correct. The scores in quiet and in noise were very strongly correlated, R = 0.96. This high correlation implies that common factors play primary roles in the perception of phonetic details in quiet and in noise. Otherwise said, hearing-aid users' problems perceiving phonetic details in noise appear to be tied to their problems perceiving phonetic details in quiet and vice versa.
通过测量59名成年助听器使用者在佩戴助听器时，在安静环境以及不同噪声水平（12人交谈的嘈杂声）下识别音节成分的能力，来评估他们感知语音细节的能力。这组声音由109个经常出现的音节成分组成（45个起首音、28个核音和36个结尾音），由八位说话者在不同的语音环境中说出。在名义安静环境中，即语音与噪声比（SNR）为40分贝时，个体听众的得分正确率约为23%至85%。在嘈杂环境中常见的SNR范围内进行平均后，个体听众的得分正确率约为10%至71%。安静环境和嘈杂环境中的得分高度相关，R = 0.96。这种高度相关性意味着，共同因素在安静环境和嘈杂环境中语音细节的感知中起主要作用。换句话说，助听器使用者在嘈杂环境嘈杂时感知语音细节的问题，似乎与他们在安静环境中感知语音细节的问题相关，反之亦然。
