Ear Canal, or External Auditory Meatus
From the pinna the sound pressure waves move into the ear canal, a simple tube running through the middle ear. This tube leads inward from the bottom of the auricula and conducts the vibrations to the tympanic cavity and amplifies frequencies in the range 3 kHz to 12 kHz.

Famous quotes containing the words ear and/or external:
“There’s nothing in this world can make me joy.
Life is as tedious as a twice-told tale,
Vexing the dull ear of a drowsy man.”
—William Shakespeare (1564–1616)
“The ideal of brotherhood of man, the building of the Just City, is one that cannot be discarded without lifelong feelings of disappointment and loss. But, if we are to live in the real world, discard it we must. Its very nobility makes the results of its breakdown doubly horrifying, and it breaks down, as it always will, not by some external agency but because it cannot work.”
—Kingsley Amis (1922–1995)
