1). We verified that the modified ear still received specific elevation-dependent spectral features by training a two-layer feedforward neural network to map the pinna filter functions of the ...

The ear can detect a time difference as slight as 30 microseconds ... Time delays of reflections from the ridges of the pinna. The first chart (left) shows the delays (in microseconds) caused by ...

Ear (aural) hematomas occur when blood vessels in the pinna rupture secondary to trauma or excessive head shaking. Blood fills the space between the skin and the cartilage, causing pain and ...
