prediction of rectal temperature from ear canal temperature

摘要

personal heat strain monitoring provides the best means for maximizing worker safety and productivity in hot jobs. The present study compared methods for reducing the environmental effect on aural canal temperature in an attempt to reduce the predictive error of a personal heat stress monitor (QST) and a simple ear thermistor (EAR). Subjects underwent three exposures in impermeable protective clothing (PC) in an environment of 30.1 deg.C wet bulb globe temperature (WBGT) wearing either ear plugs (LPG), ear moulds (MLD) or ear moulds and earmuffs (MFS).
