Core body temperature (CBT) is an important and commonly used indicator of human health and endurance performance. A rise in baseline CBT can be attributed to an onset of flu, infection or even thermoregulatory failure when it becomes excessive. Sites which have been used for measurement of CBT include the pulmonary artery, the esophagus, the rectum and the tympanic membrane. Among them, the tympanic membrane is an attractive measurement site for CBT due to its unobtrusive nature and ease of measurement facilitated, especially when continuous CBT measurements are needed for monitoring such as during military, occupational and sporting settings. However, to-date, there are still polarizing views on the suitability of tympanic membrane as a CBT site. This paper will revisit a number of key unresolved issues in the literature and also presents, for the first time, a benchmark of the middle ear temperature against temperature measurements from other sites. Results from experiments carried out on human and primate subjects will be presented to draw a fresh set of insights against the backdrop of hypotheses and controversies.
核心体温（CBT）是人体健康和耐力表现的一个重要且常用的指标。基线核心体温升高可能归因于流感、感染的发作，甚至在体温过高时出现体温调节功能衰竭。用于测量核心体温的部位包括肺动脉、食管、直肠和鼓膜。其中，鼓膜因其不显眼的特性以及便于测量，特别是在军事、职业和体育环境等需要持续监测核心体温的情况下，是一个有吸引力的核心体温测量部位。然而，迄今为止，对于鼓膜作为核心体温测量部位的适用性仍存在两极分化的观点。本文将重新审视文献中一些关键的未解决问题，并首次给出中耳温度与其他部位温度测量的基准对比。将展示在人类和灵长类动物受试者上进行的实验结果，以便在假设和争议的背景下得出一组新的见解。
