健康的听力取决于灵敏的耳朵和足够的大脑处理。听力和认知的基本方面都随着年龄的增长而下降，但很大程度上不知道一个是如何影响另一个的。目前听力的标准测量，纯音听力图不是很认知要求，并不能很好地预测最重要但最具挑战性的听力使用，在嘈杂的环境中听演讲。我们分析了英国生物银行的数据，这些数据询问了40-69奥尔兹的听力，并评估了他们在噪音中言语听力和认知测试中的能力。大约50万志愿者是通过NHS登记册招募的。受访者在英国各地专门设计的社区测试中心完成了“全身”测试。客观的听力（语音数字识别噪声）和认知（推理，记忆，处理速度）数据进行了分析，使用逻辑和多元回归方法。噪声中的言语听力随着年龄的增长而呈指数下降，从50岁左右开始，这与之前的听力图数据不同，该数据显示男性从<40岁开始线性下降，女性的听力损失一直较少。噪音中的言语听力下降在认知得分较低的人中尤为明显。在研究人群中，认知能力下降和年龄增加都与噪声中听语音的能力下降（分别为0.70和0.89 dB）独立相关。男性主观上报告的听力困难率比女性高出60%。工作场所噪声史与噪声中主观听力和客观言语听力的困难相关。休闲噪音的历史与主观的，但不与客观的听力困难。老年人的认知处理能力下降，这与在噪音中听到语音的能力下降有关，这是通过识别记录的语音数字来衡量的。听力困难的主观报告通常显示出比客观措施更高的患病率，这表明目前的客观方法可以进一步扩展。
Healthy hearing depends on sensitive ears and adequate brain processing. Essential aspects of both hearing and cognition decline with advancing age, but it is largely unknown how one influences the other. The current standard measure of hearing, the pure-tone audiogram is not very cognitively demanding and does not predict well the most important yet challenging use of hearing, listening to speech in noisy environments. We analysed data from UK Biobank that asked 40–69 year olds about their hearing, and assessed their ability on tests of speech-in-noise hearing and cognition. About half a million volunteers were recruited through NHS registers. Respondents completed ‘whole-body’ testing in purpose-designed, community-based test centres across the UK. Objective hearing (spoken digit recognition in noise) and cognitive (reasoning, memory, processing speed) data were analysed using logistic and multiple regression methods. Speech hearing in noise declined exponentially with age for both sexes from about 50 years, differing from previous audiogram data that showed a more linear decline from <40 years for men, and consistently less hearing loss for women. The decline in speech-in-noise hearing was especially dramatic among those with lower cognitive scores. Decreasing cognitive ability and increasing age were both independently associated with decreasing ability to hear speech-in-noise (0.70 and 0.89 dB, respectively) among the population studied. Men subjectively reported up to 60% higher rates of difficulty hearing than women. Workplace noise history associated with difficulty in both subjective hearing and objective speech hearing in noise. Leisure noise history was associated with subjective, but not with objective difficulty hearing. Older people have declining cognitive processing ability associated with reduced ability to hear speech in noise, measured by recognition of recorded spoken digits. Subjective reports of hearing difficulty generally show a higher prevalence than objective measures, suggesting that current objective methods could be extended further.
