    The function of the organ of Corti is to convert sounds into electrical signals that can be transmitted to the brainstem through the auditory nerve. [2] It is the auricle and middle ear that act as mechanical transformers and amplifiers so that the sound waves end up with amplitudes 22 times greater than when they entered the ear.

  7. Earlobe - Wikipedia

    The human earlobe (lobulus auriculae), the lower portion of the outer ear, is composed of tough areolar and adipose connective tissues, lacking the firmness and elasticity of the rest of the auricle (the external structure of the ear). In some cases the lower lobe is connected to the side of the face.
