Opening through which sounds collected by the pinna reach the tympanic cavity.
tragus ![click to hear](/images/speaker.jpg)
Flat triangular protuberance located in front of the acoustic meatus, protecting especially the concha.

Deep depression separating the helix from the tragus.
crus of helix ![click to hear](/images/speaker.jpg)
Front portion of the helix beginning at the base of the concha.

Small triangular protuberance at the terminal end of the antihelix.
intertragic notch ![click to hear](/images/speaker.jpg)
Deep depression at the base of the acoustic meatus between the antitragus and the tragus.
concha ![click to hear](/images/speaker.jpg)
