28 wrz 2024 · Tragus: The tragus is a small, pointed flap of cartilage that projects outward from the front of the auricle, covering part of the external auditory canal. It is positioned anterior to the concha and plays a role in sound wave entry.
Due to its anatomy, the pinna largely eliminates a small segment of the frequency spectrum; this band is called the pinna notch. The pinna works differently for low and high frequency sounds. For low frequencies, it behaves similarly to a reflector dish, directing sounds toward the ear canal.
The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin. There are three different parts to the outer ear; the tragus, helix and the lobule.
24 lis 2022 · There is a cartilaginous portion, known as the pinna or auricle and a bony, tubular segment called the external acoustic meatus. The former portion of the auditory system is the first point at which sound wave modification begins.
3 lis 2023 · This concha is covered with a triangular cartilaginous process called the tragus. The base of the tragus is attached to facial skin, whereas its apex partially covers the entrance to the external acoustic meatus. Opposite to the tragus, there is also a cartilaginous elevation above the lobule called antitragus. External acoustic meatus
28 wrz 2024 · The external ear refers to the outermost part of the ear, which is responsible for collecting sound and directing it into the auditory system. It is made up of two primary components: the auricle (or pinna) and the external auditory canal (also known as the ear canal).
