Abstract
Infrared tympanic thermometers (ITT) are used to determine core body temperature in human subjects. Current models are unreliable in non-clinical and non-laboratory situations. A new ITT device is being developed to correct this problem. To ensure that this device reliably measures the core body temperature, thermal casts of the human ear were created. These casts can accurately mimic and monitor the thermal conditions of the human auditory canal by using heating wire and thermocouples. They are also anatomically accurate and represent the various shapes and sizes of adult ear canals. It is recommended that new ITT devices should be subjected to testing with these thermal models since the ability to control and monitor the temperature of the casts allow for an accurate analysis.
