When the wavelength of a sound equals the head width of an animal, the sound is
A) artificially increased in pitch, making the sound easier to localize.
B) degraded by bone and soft tissue, making the sound more difficult to localize.
C) difficult to localize, because the phase of the sound wave is the same in each ear.
D) easy to localize, because the phase of the sound wave is the same in each ear.

When the wavelength of a sound equals the head width of an animal, it becomes difficult to localize the sound because the phase of the sound wave is the same in each ear. This means that the sound arrives at both ears at the same time, making it challenging for the animal to discern the direction from which the sound is coming.
