What determines the pitch of a sound?

• The color of the sound waves

• The number of waves passing a certain point

• The sound's amplitude

• The ear's shape

What part of the ear catches sound waves?

• The pinna

• The eardrum

• The auditory nerve

• The cochlea

What are the three tiny bones in the middle ear known as?

• Malleus, incus, and stapes

• Radius, ulna, and humerus

• Femur, tibia, and fibula

• Carpals, metacarpals, and phalanges

What does the inner ear's cochlea do?
