===Ear canal===
{{Main|Ear canal}}
From the pinna, the [[Sound#Waves|sound wave]]s move into the [[ear canal]] (also known as the ''external acoustic meatus'') a simple tube running through to 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 2&nbsp;[[Kilohertz|kHz]] to 5&nbsp;kHz.<ref>{{Cite web |title=Acoustics Chapter One: The ear |url=https://cmtext.indiana.edu/acoustics/chapter1_ear.php#:~:text=The%20auditory%20canal%20behaves%20as,hammer,%20anvil%20and%20stirrup). |access-date=2024-10-21 |website=cmtext.indiana.edu}}</ref>
