This hand-drawn illustration shows concentric black arcs representing sound waves moving toward a detailed side-view of the human outer ear (pinna). The ear is rendered in soft peach tones with bold black outlines, emphasizing anatomical structure while maintaining a clear, educational visual style. The image conveys the concept of acoustic signal reception before neural processing begins.
