The accuracy of this method is attributed to the tympanic membrane's close anato~nic proximity to the hypothalamic thermore-gulatory centre and common blood supply from the carotid artery. Since temperature is displayed within one second, the ear thermometer (which is marketed in the shape of an otoscope) offers a les stressful and faster method of temperature measurement, Therefore, it is especially useful in children. Neither cerumen nor otitis media significantly affect the readings. So, infrared tympanic thermometry offers a relatively noninvasive, comfortable and faster option compared to conventional thermometry.
