Except for people with certain conditions of total deafness, no human being has ever experienced silence. Lying still in the middle of the desert on a totally still night, or, more conveniently, in a sound proof room , may provide a situation where there is no sound in the air to be transmitted to the eardrum (tympanum). But the flow of blood through the micro-veins of the ear parts themselves constantly keep the eardrum vibrating, and transmitting sound messages to the brain. In this sense, from birth to death, we never experience silence. See also Hearing Yourself Sing.
