do not have outside ears that direct sound inward to the ear drum as ours do. But they do have an ear drum of sorts, an inner ear, a brain, and most frogs have a middle ear. They hear with these structures and one more--their lungs!
The ear structures function much as ours. The eardrum of most frogs is a membrane surrounded by a cartilage ring. Sound waves vibrate the eardrum, which wiggles a rod connected to the eardrum, which sloshes fluid in the inner ear, which waves hairs in hair cells. The hair cells contact nerve fibers, which generate electrical pulses. Nerve fibers carry the signals to the brain, which interprets the nerve signals as sound. That's how the ear structures work.
The lungs are a different story. Suppose a tree falls in the night. And suppose a frog squats within hearing range of the noise. Then, just as we discussed, his eardrums vibrate in response to the noise. But there's more: his lungs do, too. Indeed, his lungs are only slightly less sensitive than his eardrums.

Frogs do have ears for audio functions just like human beings.
The difference is we are mammals and like all other mammals we have external ear or pinnae to gather the sound waves.
In animals like donkeys and cattle these are very well developed and the ear muscles/external ear can be moved in the direction of sound, this is survival instinct.
In frogs, on the other hand there are no external ears / pinnae hence you are confused.
The ear in them starts with the eardrum or the tympanum. It can be seen in a circular form exactly where you expect the ear. The diameter is less than a centimeter.
The sound waves that strike this tympanum/ tympanic membrane are transmitted to the inner ear to hear.
In birds also the external ear is absent.
In mating season the croaking sound made by the male frog is heard by the female frog and suitably responded to.
Since it is flush with the skin/ at the same level with the skin it is not easily noticeable.
Perhaps that is the reason the ceramic caster did not care to show it.

HAHA what a question......sorry dude but i can't stop laughing. Funny question. Anyway frogs have no outer ears; their prominent eardrums are exposed on the sides of the head.

I'm not sure but if they do they can't be very good otherwise they would hear the cars coming and get out the way instead of getting squished.

They have no outer ears, but do have inner ears.
Have a look at the website below.

actually frogs do not have ears they only feel what is approaching to them by vibrations from the ground so they can rely on what will happen.

They look like two little slits on each side of its head. Sometimes they look like small cloudy circles. Ha ha, you should try to google the picture.
