Answer:
A)The external ear, which consists of the pinna, concha, and auditory meatus, gathers sound energy and focuses it on the eardrum, or tympanic membrane (Figure 13.3). One consequence of the configuration of the external ear is that it selectively boosts the sound pressure 30- to 100-fold for frequencies around 3 kHz.
B)What causes this hole? A preauricular pit is a small hole in front of the ear, toward the face, that some people are born with. This hole is connected to an unusual sinus tract under the skin. This tract is a narrow passageway under the skin that can cause infection.
C)The ear canal functions as an entryway for sound waves, which get propelled toward the tympanic membrane, known as the eardrum. When sounds enter the middle ear, they are transmitted to tiny bones called the ossicles, which consist of the stapes, the incus, and the malleus.
