Bats hear with their ears and echolocation; it picks up vibrations and then waits for them to come back to the ear. See the related question below.

The bat. It can "hear" sound waves produced by it's own voice. The shape of the waves change when they bounce off obstacles, so the bat literally navigates by it's ears.

Not unless you're a bat
A bat would hear a weaker and more stretched out echo if an object is moving away from it, as the sound waves would take longer to return. This could indicate to the bat that the object is further away.
A bat would hear a Doppler-shifted echo from an object moving away from it. This means the frequency of the echo would be lower than the frequency of the sound wave emitted by the bat. The bat's brain is able to interpret this change in frequency to understand the direction and speed of the object.

super well better then us by a long shot
echo location The bat emits a squeak, which when it reflects (echo) off an object (prey) the bat can hear that and fly to it.
