How about a "sound mirror"? Bats and dolphin in a way "view" sounds with their echolocation..

A sound mirror is just a wall.

To be fair, a visual mirror is just a special type of wall.

It has to be a very very flat and even wall, otherwise the echo image will be distorted or "blurry". Such do not really appear in nature. Just like the only natural equivalent to a visual mirror is a very still pond, viewed under an angle.

For echolocation to work, you'd basically need some sort of mold of the animal itself that moved in real-time to match it.
