Is there any advantage of having large ears ?

Is there any priority in the way the brain processes sensory inputs eg. visual over auditory ?

Please advise.

It helps you stay cooler, since you're able to dissipate heat more efficiently when the blood vessels are so close to the surface. When you get wet, larger ears also help use the water to remove excess heat from the body.

Most of the times what appears as large ears are prominent ears.

Otherwise there is a myth that says that when you have large extremities you have large extremities under the belt also. I don't know if it works for the ears though.

So it's not the size that matters, but how you make them wiggle.

You can - or could at one time - buy a pair of large ear extensions in a headset, like Mickey Mouse ears only cupping your real ones, for listening to classical music - apparently they worked much better than they looked.

 

As anyone can demonstrate by cupping their ears with their hands, changing the shape and size of your ears alters their performance. http://www.independent.co.uk/news/shape-of-ears-affects-power-of-hearing-1175189.html Pointed ears, for example, with a little practice allow better localization on the vertical axis (by changing the frequency profile with respect to incident vertical angle).

 

Most mammals hear better than they do anything else - the mammalian ear is top quality, very sophisticated. Even humans, with their visually specialized setup, hear better in many respects than they see (much faster and in higher resolution, for starters - a flip book or movie can fool your eye at 25 frames per second, as if a fairly slow drum roll were to be heard as a single continuous tone).
