why as they help us in hearing
nooo your eardrum helps u to hear... not pinna .
oh yeah im sorrry i hadnt checked it up soo sorry
The pinna is the only visible part of the ear (the auricle) with its special helical shape. It is the first part of the ear that reacts with sound. The function of the pinna is to act as a kind of funnel which assists in directing the sound further into the ear.
yup...
yehh
The ear has external, middle, and inner portions. The outer ear is called the pinna and is made of ridged cartilage covered by skin. Sound funnels through the pinna into the external auditory canal, a short tube that ends at the eardrum (tympanic membrane).
External ear may be vestigial but it has many functions which are protective and increases the efficiency of hearing
The ‘hills’ and valleys’ of the pinna interfere with sound and modify the spectrum. One may also describe the pinna as a form of audio filter.
The funnel-like shape gives away another important function, the amplification of sound.
